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.
