Plastic medicine bottles are increasingly recognized by manufacturers in pharmaceutical packaging. The design of plastic medical bottles in the diameter of the bottle mouth is usually considered to cover the volume of the drug plus the appropriate margin space. The shape of the neck of the bottle has good compatibility with the cap, and the tightness of the bottle mouth and the cap and the torque after applying the torque have strong moisture resistance. Now the plastic bottle mouth is made of aluminum foil gasket electromagnetic induction sealing, which has the functions of moisture proof, sealing and anti-theft.

Pressure Cap Bottle
The plastic medicine bottle body is a circular rotating body with a cylindrical shape. If the bottle wall is too thick, the weight of the bottle body will increase, the raw material consumption will increase, and the stress and contraction amount in the bottle will also increase, and if the bottle wall is too thin, it will be difficult to blow molding and it will have low strength and is easy to penetrate. In order to improve the barrier properties of plastic bottles and their strength, the thickness of the bottle is generally 1.2mm-1.5mm. The bottom of the plastic bottle is designed with a concave bottom or a flat bottom double rounded structure to enhance the internal pressure resistance of the bottle and ensure the stability of the bottle. Since the high-quality medicinal plastic bottles are produced in the purification workshop that meets the GHP requirements, the cleanliness level is the same as that of the pharmaceutical plant filling stage. The pharmaceutical factory does not need to carry out bottle cleaning, and the disinfection can be directly filled, which significantly reduces the production cost of the pharmaceutical factory.

Moisture-proof Bottle
In order to ensure that the drug is not affected by moisture or deterioration during the period of validity, the plastic medicine bottle should have good sealing and barrier properties and can prevent the influence of light, heat, water vapor and oxygen on the drug. The specificity of medicine packaging and medication, from a few milliliters to about 1000ml, the shape is mostly round, but also square, oval and other shapes. The inner wall of the bottle is in direct contact with the drug, and the bottle material must meet the requirements of the drug packaging to ensure the safety of the drug. Oral solid and liquid medicinal plastic bottles are a type of packaging material that can be used for pharmaceutical packaging without washing and sterilization. Therefore, there are high requirements for microbial limits, and the production environment and production process should comply with the relevant regulations.
