Plastic bottles are made of PET, PP, PE, PC, etc. The following is an introduction to the characteristics of these materials
PET：Transparent, non-toxic, impact resistant, not high temperature resistant, generally containing mineral water, cola, peanut oil, cosmetics, must be cold filling, one-time use (not high temperature disinfection).
PP：Non-toxic, transparent, with a certain degree of heat resistance and impact resistance, generally containing fruit juice drinks, shampoo, can be hot filled (very important for fruit juice drinks), can not be sterilized by pressure cooker, transparency is not good.
PE：PE bottles are similar to PP bottles, with better toughness than PP, but poor rigidity and heat resistance, and good solvent resistance. Plastic soy sauce bottles seem to be PE bottles, and a small amount of wine and kerosene can be used.
PC：Transparent, impact-resistant, high-temperature resistant, more expensive materials, 5 gallon purified water bottles are used most, and can be sterilized by high-temperature steam. The key to the choice of plastic bottle material is to decide what material you want to use, whether it is corrosive, appearance requirements, etc.
