The difference in bottle shape will affect the adjustment of gob shape, the speed of machine bottle production, the adjustment of the initial mold and the molding nozzle, and the blowing air pressure, etc. The bottle shape If the gap is too large, the bottom and finish of the produced glass bottles will also change, reducing the genuine rate.

3. The bottle mouth of glass bottle containers must be the same. The wide-mouth essential oil glass bottle and the wide-mouth bottle are matched, and the small-mouth bottle and the small-mouth bottle are together, which is conducive to the adjustment of the shape of the glass gob, otherwise it will affect the speed of the gob falling into the initial mold. Consume man-hours.

4. The quantity of several types of counterweight glass bottles should be the same, and the production should be changed at the same time and offline at the same time.

5.When these glass bottles are produced in combination, the production speed of the glass bottle production line process will be slightly reduced, and the output will not be the same as the normal production process, but many glass bottle factories will take these costs into account to meet these differences. Customer demand.

HOW TO PROTECT GLASS BOTTLE PACKAGING FROM LIGHT?(2022年11月28日)

sizepackage — 2022-11-25T11:26:16+0900

http://www.sizepackage.com/products/30ml-green-glass-bottle-with-18-415-bamboo-te-crc-dropper-cap.html

From food, medicine, cosmetics to pesticides, glass bottle packaging is involved in almost every field. Glass bottle packaging has a long history and is safer, more practical and reassuring than other packaging. However, there are also some defects in the packaging of essential oil bottles and green glass dropper bottles.

1. Packaging of glass bottles for different purposes

The glass bottle is transparent, which is a major advantage of its packaging. Compared with metal material packaging, it can display the packaged products at a glance and stimulate our desire to buy.

However, since glass bottles are used for the packaging of food and medicine, some products need to be protected from light, such as juices and medicines. The exposure of these products to light will affect the shelf life of the products, which requires the improvement of the light-shielding properties of glass bottles.

2. Two ways to avoid light in glass bottle packaging

One is to use colored essential oil bottles or glass bottles. For example, essential oils are packaged in dark glass bottles to avoid light.

Another way is to improve the material of the transparent essential oil bottle and glass bottle itself, and reduce the harm of light to the product through the absorption of light by the medium of the glass bottle.

EIGHT FACTORS THAT AFFECT THE SMOOTHNESS OF GLASS BOTTLE CONTAINERS(2022年11月27日)

sizepackage — 2022-11-25T11:25:34+0900

http://www.sizepackage.com/products/plastic-jar/

After the glass bottle container is produced and formed, sometimes a lot of spots of wrinkles, bubbles, scratches, etc. appear on the bottle body, caused mainly by the following reasons:

1. When the glass bottle blank falls into the preliminary mold, it cannot accurately enter it, and it rubs excessively with the mold wall to form creases. After blowing, the creases spread and enlarge, and folds are formed on the glass bottle body.

2. The scissor marks of the feeder on the upper part of the glass bottle mold are too large, and the scissor scars appear on the bottle body after individual bottles are formed.

3. The material of the first mold and the finished mold of the glass bottle is poor, the density is not enough, and the oxidation is too fast after high temperature. Minor dents are formed on the surface of the mold, which causes the surface of the formed glass bottle to be dirty.

4. Poor glass bottle mold oil quality will cause insufficient mold lubrication, lower dripping speed, and rapid change of material type.

5. The design of the initial mold of the glass bottle container is unreasonable. The mold cavity is large or small, and the material droplets are blown and spread unevenly after entering the forming mold, which will cause spots on the glass bottle body.

6. The dripping speed of the glass bottle mold machine is uneven, and the improper adjustment of the air nozzle will cause the temperature of the glass bottle to be inconsistent with the mold. It is easy to create cold spots on the glass bottle body, directly affecting the finish.

7. The glass bottle material in the kiln is not clean, or the material temperature is uneven, which will also cause bubbles, small particles, and small hemp blanks to appear in the output glass jars.

8.If the speed of the glass bottle mold line machine is too fast or slow, the glass bottle body will be uneven, and the bottle wall thickness will be different, resulting in mottling.

THE LIGHTENING OF ESSENTIAL OIL BOTTLES AND GLASS BOTTLES IS NOT SEEMINGLY GOOD(2022年11月26日)

sizepackage — 2022-11-25T11:24:55+0900

http://www.sizepackage.com/products/plastic-bottle/

Plastic bottle are being lightweight, and glass bottles are also being lightweight.

Ⅰ. Lightweight advantages of essential oil bottles and glass bottles

On the one hand, the lightweight of glass bottles saves a lot of raw materials, which means cost reduction for a manufacturer of essential oil bottles and glass bottles.

On the other hand, as the weight of the glass bottle is reduced, the logistics cost during transportation will also be greatly saved. The many advantages of lightweight glass bottles make the entire industry have high expectations.

However, the lightweight of glass bottles is not as good as it seems. The lightweight technology of glass bottles is difficult to overcome. The body of the glass bottle must be able to withstand a certain amount of pressure. When the bottle wall becomes thinner, the ability of the glass bottle to withstand pressure will drop rapidly. So this kind of lightweight technology is difficult to overcome.

Ⅱ. The lightweight of essential oil bottles and glass bottles should be carefully selected

For people's consumption habits, the heavy texture of glass bottles can better reflect the grade and luxury of a product. Many high-end products are packaged in glass bottles because of this consideration. Lightweight makes the glass bottle lose this advantage. In addition, similar to the wine glass bottle, wine has certain requirements for the color of the glass bottle, not the thinner the better.

Regarding the lightweight of essential oil bottles and glass bottles, each of us should have a more sober attitude and not blindly.

http://www.sizepackage.com/products/glass-bottle/

Perfume glass bottle factory usually uses medicinal glass bottle materials to produce perfume bottles, so what are the advantages of perfume glass bottle?

Ⅰ. Good chemical stability of medicinal glass bottle

When medicinal glass bottles are used as perfume bottles and glass containers, there is almost no eluate from the container materials. Compared with other containers, medicinal glass bottles have good chemical stability and durability, which is the advantage of medicinal glass bottles over other packaging containers.

2. Good sealing performance of medicinal glass bottle

The glass perfume bottle can guarantee a good seal. Unlike some plastic bottles and paper containers, glass containers are not air-permeable, so they can prevent the influence of outside air on the smell of perfume.

3. Strong pressure resistance of medicinal glass bottle

The relationship between the strength of the glass perfume bottle and the chemical composition of the glass is negligible, but the condition of the glass bottle surface is closely related to its tensile properties. The glass surface is scratched or bruised, even the slightest damage, the strength will be greatly reduced.

4. Diversified shapes of medicinal glass bottle

According to the type of product, the presence or absence of gas, and whether it is sterilized or not, the glass perfume bottle can be designed into various shapes suitable for sale, and its capacity and sealing form can be freely selected. Perfume glass bottle factory usually designs the glass packaging bottle beautifully, making it very popular.

HOW ARE PLASTIC BOTTLES MADE?(2021年11月24日)

sizepackage — 2021-11-15T14:50:01+0900

http://www.sizepackage.com/how-are-plastic-bottles-made.html

Technical process of plastic bottle manufacturing:

The molding process of plastic bottles refers to the process of making final plastic products from polymers manufactured by synthetic resin manufacturers. Processing methods (commonly referred to as one-time processing of plastics) include compression molding (compression molding), extrusion molding (extrusion molding), injection molding (injection molding), blow molding (hollow molding), calendering, etc.

1. Compression molding

Compression molding is also called compression molding or compression molding. Compression molding is mainly used for the molding of thermosetting plastics such as phenolic resin, urea-formaldehyde resin, and unsaturated polyester resin.

2. Extrusion

Extrusion, also known as extrusion molding, is a method that uses an extruder (extruder) to continuously pass heated resin through a mold to extrude products of the desired shape. Extrusion is sometimes also used in the molding of thermoset plastics and can be used in the molding of foam plastics. The advantage of extrusion is that products of various shapes can be extruded, the production efficiency is high, and it can be automated and continuous production; the disadvantage is that thermosetting plastics cannot be processed by this method widely, and the product size is prone to deviation.

3. Injection molding

Injection molding is also called injection molding. Injection molding is a method that uses an injection molding machine (or injection machine) to inject thermoplastic melt into a mold under high pressure, and then cool and solidify to obtain a product. Injection molding can also be used for the molding of thermosetting plastics and foam plastics. The advantages of injection molding are fast production speed, high efficiency, automatic operation, and the ability to form parts with complex shapes, which is especially suitable for mass production. The disadvantage is that the cost of equipment and molds is high, and it is difficult to clean the injection molding machine.

4. Blow molding

Blow molding is also called hollow blow molding or hollow molding. Blow molding is a method in which the hot resin parison closed in the mold is blown into hollow products by the pressure of compressed air. Blow molding includes two methods: blown film and blown hollow products. Blow molding can be used to produce film products, various bottles, barrels, pots, and children's toys.

5. Calender

Calendering is to process the resin and various additives through the expected treatment (kneading, filtering, etc.) into a film or sheet through the gap of two or more calender rolls that turn in opposite directions, and then peel it off from the calender roll , A molding method that is cooled and shaped. Calendering is a molding method mainly used for polyvinyl chloride resin, which can produce films, sheets, plates, artificial leather, floor tiles and other products.
6. Foam molding

The process of adding appropriate foaming agents to foaming materials (PVC, PE, PS, etc.) to make plastics have a microporous structure. Almost all thermosetting and thermoplastic plastics can be made into foam. According to the cell structure, it is divided into open-cell foam (most of the pores are connected to each other) and closed-cell foam (most of the pores are separated from each other). This is mainly due to the manufacturing method (divided into chemical foaming, physical foam And mechanical foaming).

Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles are widely used polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials, and after adding corresponding organic solvents, after high temperature heating, they are blow molded, extruded, or injection molded through plastic molds Plastic container.

It is mainly used for liquid or solid disposable plastic packaging containers such as beverages, food, pickles, honey, dried fruits, edible oil, and agricultural and veterinary drugs. Plastic bottles are not easily broken, low cost, high transparency, and food-grade raw materials.

Plastic bottles are made of polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials. After adding corresponding organic solvents, they are heated at high temperatures and then blow molded, extruded, or injection molded through plastic molds. Plastic bottles are not easily broken, low cost, high transparency, and food-grade raw materials.

When using plastic products, pay special attention to avoid contact with vinegar, detergent, etc., and avoid direct sunlight, high temperature, etc., to avoid chemical reactions. In addition, when you buy plastic tableware, you should choose plastic products with PE (polyethylene) or PP (polypropylene) labels, less decorative patterns, colorless, odorless, and smooth surface.

The main raw material for making beverage bottles is polypropylene plastic, which is non-toxic and harmless. It is used to hold soda and cola-type beverages without harmful effects on the human body; but because plastic bottles still contain a small amount of vinyl monomer, if the fat-soluble alcohol, vinegar, etc. is stored for a long time, chemical reaction will happen. Long-term consumption of food contaminated with ethylene can cause dizziness, headache, nausea, loss of appetite, and memory loss. In severe cases, it may also lead to anemia. In addition, if you use a beverage bottle to hold wine, vinegar, etc., the bottle will age due to the effects of oxygen, ultraviolet rays, etc., releasing more vinyl monomers, which will deteriorate the wine, vinegar, etc. stored in the bottle for a long time. For beverage bottles that are not allowed to contain other liquids and cause accidental injuries, it is recommended that beverage companies indicate warnings on the bottle packaging.

INTRODUCTION OF PLASTIC JARS(2021年11月22日)

sizepackage — 2021-11-15T14:48:51+0900

http://www.sizepackage.com/introduction-of-plastic-jars.html

Plastic jars refer to small packaging containers made of plastic or plastic-based raw materials, generally with a sealable can lid.

Among plastic jars, there are few pure plastic jars. Most of them are made of plastic, paper, aluminum foil and other composite materials, while the bottom and lid are made of plastic or metal. This kind of plastic jar is also called composite tank.

Types of plastic jars:

The difference between plastic jars mainly lies in the jar body, which can be divided into two types according to its composition structure:

① Laminated composite material tank. It is made from several materials, such as plastic film, aluminum foil, cardboard, etc., into composite materials, and then extruded to form a jar body. The jar body is mostly square with rounded corners. The bottom cover is mostly plastic and is connected to the jar body by high-frequency fusion sealing.

② Multilayer material winding jar. It uses a variety of materials to be shaped into a cylinder, then cut into a jar body as required, and then connect the jar bottom and the jar lid respectively.

Performance of plastic jars:

Plastic jars have not appeared for a long time, but they have developed very rapidly. They have replaced metal jars and glass bottles on many occasions, mainly because they have many advantages:

① Light weight. The density of materials used to make plastic jars is relatively small. Compared with the quality of containers with the same volume, plastic jars are smaller than metal jars and glass bottles.

② The cost is lower. The material cost of the plastic jar is lower, and the manufacturing is easier, so the overall price is lower.

③ The product jar be reliably protected. The tank body is made of a variety of materials, with good chemical stability and barrier properties; the combination of the bottom, cover and the tank body adopts a reliable sealing structure, so the contents jar be reliably protected.

④ Good mechanical strength. Although the mechanical properties of plastic jars are slightly lower than that of metal jars and glass bottles, they are sufficient for packaging general products, and strength damage rarely occurs.

⑤ Good shelf effect. The surface of the plastic jar is easy to print and easy to decorate, which is very good for attracting customers and promoting sales.

Plastic jars also have some shortcomings: for example, the sealing quality of the bottom cover and the jar body is not stable; in vacuum packaging and pressure packaging, the strength of the jar body is sometimes not high enough.

As a new type of packaging container, plastic jars are widely used in the packaging field. They can package fruit juice, milk powder, carbonated beverages, coffee, cosmetics, oils, etc.

sizepackage — 2021-11-15T14:48:05+0900

http://www.sizepackage.com/notes-for-using-the-pipette-dropper.html

Divided into fat belly dropper and commonly used dropper. It consists of a rubber nipple and a pointed glass tube.

Use:

It is used to aspirate or add a small amount of reagents, and absorb the supernatant to separate the precipitate.

Precautions:

When dripping, keep the dropper perpendicular to the top of the container, avoid tilting, avoid standing upside down, and do not extend into the container or touch the container wall. Except for absorbing the solution, the tip of the tube should not touch other utensils to avoid contamination by impurities. Don't do it for two uses.

The ordinary dropper needs to be cleaned when it is used up, but the special dropper cannot be cleaned and needs to be used for special purpose. Just put it back into the original reagent bottle when it is used up.

When using, don't pinch it with your thumb and index finger, use your middle finger and ring finger.

Instructions:

1. When using the dropper, pinch the rubber nipple with your fingers to drive out the air in the dropper, then insert the dropper into the reagent bottle, release your finger, and the reagent will be sucked in.

2. After taking the liquid, the pipette dropper should keep the rubber head on top, do not lay it flat or upside down, to prevent the solution from flowing back and corroding the rubber head.

3. When dripping liquid, it should be suspended on the top of the beaker, do not touch the wall of the beaker, so as not to stain the dropper or cause reagent contamination.

4. Do not put the pipette dropper on the test bench or other places to avoid contaminating the dropper.

5. The used pipette dropper should be rinsed with clean water immediately for reuse.

ANALYSIS OF COMMON MATERIALS OF CLEAR PLASTIC BOTTLES(2021年11月17日)

sizepackage — 2021-11-15T14:47:23+0900

http://www.sizepackage.com/analysis-of-common-materials-of-clear-plastic-bottles.html

At present, the main materials of clear plastic bottles in the Chinese market are: PET, PP, and PVC. Let me share with you today:

PET is hard, good toughness, high strength, bright surface, environmentally friendly and non-toxic. The disadvantage is that high-frequency heating of PET is more difficult, and the price is slightly more expensive than PVC. This material is often replaced by users who require high-end products and environmentally friendly products. PET materials are general used to make plastic bottles for packaging food, beverage, and pharmaceutical industries.

pp material is particularly soft, good toughness, environmentally friendly, non-toxic, and high temperature resistant. It is often used as packaging for catering utensils or other high temperature resistant products; but its plasticity is poor, processing is difficult, surface gloss is poor, and the color becomes lighter during processing. So, it is used to make disposable plastic bottles.

PVC is soft, tough, and malleable. It can be made into transparent and various colors. It is commonly used in plastic bottles for transparent PVC packaging and cosmetic products.

THE ADVANTAGES OF DISPENSER BOTTLE AND ITS PRINCIPLE AND PROCESS OF INJECTION MOLDING(2021年11月16日)

sizepackage — 2021-11-15T14:46:53+0900

http://www.sizepackage.com/the-advantages-of-dispenser-bottle-and-its-principle-and-process-of-injection-molding.html

The dispenser bottle should mainly have the following advantages:

1. Production in Class D clean workshop, effectively ensuring the sterility of products;

2. Quantitative filling, single use, to ensure the accuracy of medication;

3. Production by injection molding process, and the product quality is stable;

4. The bottle cap is specially designed, and it can be pierced and sealed by pressing down firmly, which is convenient to use;

5. Automatic filling and packaging of the assembly line to save labor costs

The principle of dispenser bottle injection molding is to add powder or powdered plastic into the hopper of the injection machine. The plastic is heated and melted in the injection machine to keep it flowing. Then it is written into the closed mold under a certain pressure and cooled After shaping, the molten plastic solidifies and becomes the desired plastic part.

The advantages of dispenser bottle injection molding are that the molding cycle is relatively short, the production power is relatively high, and the automated production is simple to complete.

In the preparation before molding, the plastic needs to be preheated and boring to prevent defects in the appearance of the plastic part after molding or degradation, which affects the appearance and inner quality of the plastic part. When changing the material or changing the product, the barrel needs to be cleaned. The injection molding process of the drop bottle includes: feeding, plasticizing, film filling, pressure maintaining and shrinking, cooling after the gate is frozen, and demoulding. After the dispenser bottle injection molding technology is completed, the plastic parts are processed afterwards. Because of uneven plasticization or uneven crystallization, orientation, and heating and cooling of the plastic in the cavity, there will inevitably be some internal stress inside the plastic part, which will then cause the plastic part to deform or crack during use. Therefore, we should find a way eliminate.

INTRODUCTION OF GLASS BOTTLE CONTAINERS(2021年11月15日)

sizepackage — 2021-11-15T14:46:28+0900

http://www.sizepackage.com/introduction-of-glass-bottle-containers.html

Our country has had glass bottle containers since ancient times. In the past, academic circles believed that glassware was very rare in ancient times, so it should only be owned and used by a few ruling classes. However, recent research suggests that ancient glassware is not difficult to produce and manufacture, but it is not easy to preserve, so it is rare in later generations. Glass bottle is a traditional beverage packaging container in my country, and glass is also a kind of packaging material with a long history. With many packaging materials pouring into the market, glass bottle containers still occupy an important position in beverage packaging, which is inseparable from its packaging characteristics that other packaging materials cannot replace.

The main characteristics of the glass bottle container are: non-toxic, tasteless; transparent, beautiful, good p property, airtight, abundant and universal raw materials, low price, and can be used in multiple cycles. And it has the advantages of heat resistance, pressure resistance, and cleaning resistance. It can be sterilized at high temperature and can be stored at low temperature. It is precisely because of its many advantages that it has become the preferred packaging material for many beverages such as beer, fruit tea, and jujube juice.

71% of the world's beer is bottled in glass beer bottles, and China is also the country with the highest proportion of glass beer bottles in the world, accounting for 55% of the world's glass beer bottles, with more than 50 billion glass beer bottles every year. Mainstream packaging has gone through a hundred years of vicissitudes of beer packaging. It is still favored by the beer industry for its stable material structure, pollution-free, and low price. "When a company wants beautiful appearance of packaging and cool touch, the glass bottle container is the preferred packaging choice. Generally speaking, the glass bottle container is still the usual packaging used by beer companies." It has made a huge contribution to beer packaging and most people love it.

The glass bottle container production process mainly includes:

① Pre-processing of raw materials. Crush the bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.), dry the wet raw materials, and remove iron from the iron-containing raw materials to ensure the quality of the glass.

② Preparation of batch materials.

③ Melting. The glass batch material is heated at a high temperature (1550~1600 degrees) in a pool furnace or a pool furnace to form a uniform, bubble-free liquid glass that meets the molding requirements.

④ Forming. Put the liquid glass into the mold to make glass products of the required shape, such as flat plates, various utensils, etc.

⑤ Heat treatment. Through annealing, quenching and other processes, the internal stress, phase separation or crystallization of the glass is eliminated or produced, and the structural state of the glass is changed.

http://www.sizepackage.com/products/plastic-jar/

As a fragile finished product, the transportation cost of glass bottles is a permanent issue that cannot be avoided. Therefore, the localized sales of glass bottles are more significant.

Glass is the embryonic form of glass bottles and the original material for making glass bottles. At present, the number of domestic glass bottle factory is far smaller than that of plastic bottle companies, and the profitability of glass is also very low. This determines that glass bottles must rely on volume to win profits.

Glass bottles are different from plastic bottles. Although it is a fragile finished product, the glass bottle has a limited capacity without being blown and is more suitable for transportation. Glass bottle companies not only directly face glass bottle manufacturers, but also companies that have their own packaging workshops for food, beverages, medicine and so on, all need to use glass bottles.

For glass bottle companies, how to increase the profitability of a single product of glass bottles is also the key to the company's ability to be sharp in the competition while ensuring the volume. After all, the current glass bottle production threshold is relatively low, and almost every manufacturer can produce the product. However, many shopping malls' needs such as lightweight glass bottles, glass bottle data safety, and glass bottle environmental protection are in urgent need of innovation from glass bottles. As long as the preforms are improved in these aspects, it will bring good prospects for glass bottle sales. If approved, glass bottle manufacturers will also have an opportunity. For glass bottle manufacturers, they must achieve large-scale development. It is necessary to focus on large shopping malls, not just surrounding areas.

HOW TO BUY COSMETIC GLASS BOTTLES(2021年09月30日)

sizepackage — 2021-09-30T15:18:16+0900

http://www.sizepackage.com/products/plastic-container-child-proof-jar.html

"Cosmetics" actually includes skin care products, beauty salon products and perfumes. All kinds of eye cream, night cream, SOD honey and sunscreen can be classified as skin care products; shampoo, conditioner, hair dye, lipstick, eyebrow pencil, nail polish and other cosmetics can be classified as beauty salon products; and perfume can always be its own family. Cosmetic glass bottles occupies a considerable part of the value of cosmetics, and exploring cosmetic glass bottles has always been a compulsory course for many manufacturers.

1. The main functions of cosmetic glass bottles
General cosmetics are mostly liquid, cream or paste, and do not have a distinctive appearance. Only through exquisite and unique glass bottle design can it show its own characteristics. Therefore, cosmetics generally rely on glass bottles to sell well. From the perspective of consumers, it is first necessary to attract consumers' attention, and then trigger consumers' desire to buy. That is, only when the cosmetic glass bottle attracts people's attention, will the subsequent series of behaviors occur.
According to research on human eye movements, humans respond the fastest to color. The power of the glass bottle may depend on how to reconcile the color contrast to make it lively and eye-catching in the store, and soft and not dazzling after buying it home. When consumers are attracted by advertisements to stop and linger in front of cosmetic display racks. If the glass bottle makes it purchase, then the glass bottle design is a failure. Fashionable, eye-catching, energetic and interesting outer glass bottle design and new adoption are one of the means for cosmetics manufacturers to win.

2. Improving the taste for fashion
In people's daily life, cosmetics are becoming indispensable products. While cosmetics beautify their lives, they also form a consumer market that contains huge business opportunities and cannot be ignored. Various skin care concepts are emerging in an endless stream, and all kinds of cosmetic glass bottles are dazzling. Many products sell not only effects, but also fashion and culture. The fashion and culture of cosmetics are usually what we call taste.
How to reflect the taste of cosmetics, in addition to product advertising and product counter display, glass bottles are an important link. Appropriate glass bottles can not only directly stimulate the senses of consumers, but also reflect the taste of the product to the fullest. Therefore, as the "coat" of the product, the glass bottle not only has the function of holding and protecting the product, but also has the function of attracting purchase and guiding consumption.

3. Increasing value
The psychological value of cosmetics is very important. For the same 4g lipstick, the price of Shiseido, CD, Lancome, Givenchy, etc. is as high as hundreds of yuan, while the price of some brand lipsticks is generally only tens of yuan or even lower. This includes the psychological value of factors such as the appearance of the product itself, glass bottle decoration, trademark, corporate image.

GLASS BOTTLES ARE DIVIDED INTO OXIDE GLASS AND NON-OXIDE GLASS(2021年09月30日)

sizepackage — 2021-09-30T15:17:36+0900

http://www.sizepackage.com/products/30ml-100ml.html

Glass is usually divided into oxide glass and non-oxide glass according to the main components.

There are few types and quantities of non-oxide glass in glass bottles, mainly chalcogenide glass and halide glass. The anions of chalcogenide glass are mostly sulfur, selenium, tellurium, etc. The glass bottle can cut off short-wavelength light and pass yellow, red light, and near and far infrared light. It has low resistance and has switching and memory characteristics. Glass bottle halide glass has low refractive index and low dispersion, and is mostly used as optical glass.

Oxide glass is divided into silicate glass, borate glass, phosphate glass and so on. Silicate glass refers to the glass whose basic component is SiO2, which has many varieties and wide applications.

Usually according to the different content of SiO2 in glass, alkali metal and alkaline earth metal oxide in glass bottle, it is divided into:
①Quartz glass. SiO2 content is greater than 99.5%, low thermal expansion coefficient, high temperature resistance, good chemical stability, ultraviolet and infrared light transmission, high melting temperature, high viscosity, and difficult molding. It is mostly used in semiconductors, electric light sources, glass bottle light guide communications, lasers and other technologies and optical instruments.
②High silica glass. SiO2 content is about 96%, its properties are similar to quartz glass.
③ Soda lime glass. Mainly SiO2 content, 15% Na2O and 16% CaO, its low cost, easy to shape, suitable for large-scale production of glass bottles, its output accounts for 90% of practical glass. Tinted glass bottles can be used to make glass jars, flat glass, utensils, light bulbs, etc.
④ Lead silicate glass. The main components are SiO2 and PbO, which have a unique high refractive index and high volume resistance, and have good wettability with metals. They can be used to manufacture bulbs, vacuum tube stems, crystal glassware, flint optical glass, etc. Lead glass containing a lot of PbO can block X-rays and gamma rays
⑤ Aluminosilicate glass. With SiO2 and Al2O3 as the main components, it has a high softening deformation temperature and is used to make discharge bulbs, high-temperature glass thermometers, chemical combustion tubes and glass fibers.
⑥Borosilicate glass. With SiO2 and B2O3 as the main components, it has good heat resistance and chemical stability. It is used to make cooking utensils, laboratory instruments, metal welding glass, etc. Borate glass is mainly composed of B2O3, has a low melting temperature and can resist corrosion by sodium vapor.

THE MINIMUM ORDER QUANTITY REQUIREMENT OF ESSENTIAL OIL BOTTLES AND THE REASON ANALYSIS(2021年09月30日)

sizepackage — 2021-09-30T15:16:57+0900

http://www.sizepackage.com/products/0.5oz.html

Because of market development problems, many customers in the early stage of the order volume of the essential oil bottle demand is not very large, which will bring very demanding requirements to the production of glass bottle manufacturers, especially the assembly line production process. Many factories solve this problem by matching the weight of glass bottles, which is produced according to the closeness of the bottle shape to meet customer needs.

1. The first thing is to see if the weights of several matching glass bottles are close. The weight difference of the glass bottles should not exceed 3-5 grams, preferably the same, so that it will not have a big impact on the volume of the glass bottles.
2. Check whether the bottle shapes of several bottles with the same weight are close. The difference of the bottle shape will affect the adjustment of the gob shape, the speed of the machine bottle production, the adjustment of the preliminary mold and the mold nozzle and the blowing air pressure, etc. If the difference of bottle shape is too large, the bottom and finish of the produced glass bottles will also change and reduce the rate of authenticity.
3. The mouth of the essential oil bottles must be consistent. The wide mouth glass bottle and the wide mouth bottle are matched, and the small mouth bottle and the small mouth bottle are together. This is conducive to the adjustment of the shape of essential oil bottles and droppers, otherwise it will affect the speed of the gob falling into the preliminary mold and consume man-hours.
4. The quantity of several counterweight glass bottles should be the same, and the production will be changed at the same time, and they will be offline.
5. When these glass bottles are matched and produced, the production speed of the glass bottle production line will be slightly reduced, and the output will not be the same as the normal production process, but many glass bottle factories will take these costs into consideration to meet these demands of differenct customer.

SMALL DROPPER COSMETICS BOTTLES ARE POPULAR IN THE MARKET(2021年09月30日)

sizepackage — 2021-09-30T15:15:59+0900

http://www.sizepackage.com/products/30ml-green-glass-bottle-with-18-415-bamboo-te-crc-dropper-cap.html

Q: Recently, many new beauty care products have appeared in dropper cosmetic glass bottles, and the "small dropper cosmetic bottle" has become a favorite of consumers. What do you think of this trend of "small dropper cosmetic bottle"?
A: The skin care products of the dropper cosmetic bottle will easily give people the association of a laboratory pharmacy bottle. In addition, the unit of liquid dripped from the dropper can be calculated in "drops", which is often more accurate than the push-type bottle device The "small amount" use effect of the essence, if it is a high-concentration serum, the use amount can be reduced to "drops", which is more suitable for small dropper cosmetic bottles. Of course, this will also give consumers a more "pure" feeling. The way the dropper bottle is used will minimize the amount taken each time, so it is very suitable for more concentrated liquid essence products. As for the current trend of small dropper cosmetic bottles, which are the real "power" and which are only used as marketing gimmicks, it depends on whether the essence contained in the bottle is sufficiently "concentrated".

Q: In daily maintenance, what is your personal impression of the skin care products of dropper cosmetic glass bottles?
A: A good dropper cosmetic bottle skin care product, even if you use 1 to 2 drops, it can completely extend the entire face skin. At the same time, due to its liquid texture, it will have a faster absorption effect than cream-like essence. The disadvantage of the small dropper cosmetic glass bottles is that when the essence cannot be absorbed at the end of use, there may still be 1/10 of the essence at the bottom of the bottle. At this time, it is recommended to take out the dropper and pour the essence directly through the mouth of the bottle which is out of use. However, you must use up the remaining essence of the dropper bottle as soon as possible to avoid qualitative changes.

Q: Under what conditions do you usually need to choose a "small dropper cosmetic bottle" for your skin, and how can you choose a "small dropper cosmetic bottle" that suits you?
A: It depends on the contents of the skin care products in the dropper cosmetic bottle. With the current dropper-type skin care products, the functions have been extended to moisturizing, repairing, anti-wrinkle, whitening, etc., so the first consideration is to choose according to your actual skin care needs. In addition, due to the pure texture, it is recommended not to use too much. Often a few drops (one tube) is enough. Using too much will not be better and there is a risk of waste.Because the skin care of the small dropper cosmetic bottle is liquid-like and absorbs quickly, it is suitable for all skin types. However, if it is dry skin, it is recommended to apply a lotion cream with a water-locking effect afterwards to get the small dropper cosmetic bottles exert better skin care benefits.

HOW ARE CLEAR GLASS BOTTLES MADE(2021年09月30日)

sizepackage — 2021-09-30T15:15:26+0900

http://www.sizepackage.com/products/30ml-blue-glass-bottle-with-18-415-glossy-aluminium-cap-for-cosmetic-oil.html

How are clear glass bottles glass formed? Let us take a look together.

The glass of the cosmetic clear glass bottles is made by eutectic melting of sand, sodium carbonate and calcium carbonate; it can also be made by using a mixture of sodium sulfate and carbon instead of sodium carbonate. Some other glasses, such as potassium glass, is a kind of glass that is more resistant to high temperature, harder and more chemically resistant. It can be made by using potassium carbonate or potassium sulfate to partially replace sodium salt when melting glass. It is mainly used for manufacturing experiments. Chemical containers commonly used in the laboratory.

Flint glass is a kind of high-density and high-refractive-index glass. It can be made by replacing the calcium in soda glass with lead when melting glass. It is suitable for manufacturing optical glass and engraved glass products. Extra-hard glass has a small thermal expansion coefficient, is resistant to sudden cold and heat, high temperature and chemical corrosion. It can reduce the sodium content and maintain the high content of silicon dioxide when melting the glass. To make it, it needs to add 12% to 15% boron trioxide, so it is mainly used to make higher-level chemical reaction vessels.

Adding a small amount of glass coloring agent when melting glass can produce various colored glasses. Copper (Ⅱ) or chromium oxide (Ⅲ) produces green; cobalt (Ⅱ) produces blue; manganese dioxide produces purple; tin dioxide or calcium fluoride produces milky white; uranium compounds produce yellow-green fluorescence; colloidal selenium produces ruby color; colloidal gold produces red, red-violet or blue; cuprous oxide produces red, green or blue; ferrous compounds produce green, black in large quantities; iron (Ⅲ) compounds produce yellow. When making glass, because the raw material contains impurities of ferrous iron, the glass often becomes greenish. A small amount of manganese dioxide or selenium can be added to make it colorless glass.

Glass is made of a mixture of different silicates. Ordinary glass, also known as soda glass, is a mixture of sodium silicate, calcium silicate and excess silicon dioxide. It is usually made by the eutectic of sand, sodium carbonate and calcium carbonate, which can also be made by fusion of sodium carbonate and carbon instead of sodium carbonate.

IRREPLACEABLE ADVANTAGES OF GLASS PACKAGING(2021年09月30日)

sizepackage — 2021-09-30T15:14:47+0900

http://www.sizepackage.com/products/green.html

As far as the current situation is concerned, plastic bottle packaging has obvious advantages. It is light and cheap, and can be made into various sizes with transparent or opaque appearance. At the same time, the plastic packaging delivers good printing perforamnce. The manual, logo and bar code can be directly printed on the surface of the container by means of heat transfer printing, inkjet printing, printing and other methods. And in recent years, the application of PET resin in the application of cosmetic containers has developed rapidly, which has contributed to the great revolution of replacing glass bottles with plastics. Plastic products have occupied more than 80% of the cosmetics packaging market, and they have become the most important packaging containers for cosmetics.

Compared with the proportion of plastic packaging, the proportion of glass bottle packaging in cosmetic is small, which is less than 8%. However, glass packaging still has irreplaceable advantages in this field. In the short term, it is still the preferred material for high-end cosmetics. The reasons for this situation are as follows.

First, the quality of glass packaging is better than that of plastic bottles. Nobleness and elegance are the charms of glass bottles. Glass bottles can be made into frosted or transparent style. At the same time, the massiness of glass bottles can double the trust of consumers and improve the grade of cosmetics, which can not be achieved by plastic packaging. At present, most perfumes are packaged in glass bottles. For example, packaging design of the female perfume BVLGARI, made in Italy, inherits the tradition of delicacy and excellency. The fairshaped frosted glass bottles highlight its simple lines, and the mildness of its emerald bottle body, conveying pure, fresh, graceful and amicable characteristics.

Second, glass packaging is more airtight. As for cosmetics with whitening and nourishing effects, they contain a lot of nutrients just like food. As a result, they are prone to get oxidized, and require high airtight packaging insulate them from oxygen. In addition, volatile perfume also requires high barrier packaging. Glass bottles have strong barrier property and are undoubtedly more competent than plastic bottles in protecting the contents. Therefore, glass bottle packaging is still the first choice for some high-end cosmetics.

Glass products exist in our daily life. Most people are fond of glass products because it is crystal clear and makes people feel clean. Glass bottle wholesalers introduces that the maintenance and repair of glass products are also very important.

Several ways to maintain glass bottles:

1. During daily cleaning of glass products, wiping with a damp towel or newspaper. In case of stains, use a towel dipped in beer or warm vinegar to wipe it off. In addition, you can also use the glass cleaners, avoid using a strong acid and alkali solution for cleaning. The glass surface is easy to frost in winter, and it can be wiped with a cloth dipped in concentrated brine or white wine. The effect is very good. Using plastic wrap and a wet cloth sprayed with detergent can also regenerate the glass that is often stained with oil.

2. Always be careful not to force the glass surface. To prevent scratches on the glass surface, it is best to lay a table cloth. When placing things on glass furniture, handle them gently and avoid collision. To place objects stably, heavy objects should be placed on the bottom of the glass furniture to prevent the furniture's unstable center of gravity from causing tipping. Avoid moisture and stay away from the stove. It must be isolated from chemical reagents such as acids and alkalis to prevent corrosion and deterioration.

3. The manufacturer of wholesale glass bottles introduces that if the frosted glass with patterns is dirty, it can be removed with a toothbrush dipped in detergent. Remove in a circular motion along the pattern. In addition, you can also drop some kerosene on the glass or use chalk ash and gypsum powder dipped in water to dry on the glass, and then wipe it with a clean cloth or cotton, so that the glass will be clean and bright. Glass furniture is best placed in a fixed place. Don't move around randomly.

SIZE PLASTIC,a plastic jar company, is a leading supplier of glass bottle wholesale, glass jar wholesale, plastic bottle wholesale, plastic jar wholesale ,green glass dropper bottles wholesale and child proof plastic containers wholesale.

Ordinary glass bottles are made of quartz sand, soda ash and limestone. It is a mixture of unfixed silicates.

The coloring principle of colored glass bottles is to add compounds such as Co, Mn, Ni, Fe, Cu and other transition elements to the silicate during smelting. These elements exist in the glass in the ionic state. Because of their valence electrons transition between different energy levels (ground state and excited state), they cause selective absorption of visible light and coloration, such as colored glass bottles made of cobalt blue, manganese violet, nickel green and other colored glasses.

Although these added transition metal elements exist in the form of ions, these ions are not simply decomposed. These ions form a four- or six-coordinate complex with silicate oxygen in the glass, which is very stable. Heavy metal ions in colored glass bottles will not decompose.

Although the glass bottles produced by coloured glass bottle suppliers are becoming more and more gorgeous, its manufacturing technology has basically not changed since its appearance.
