What are the common raw materials used in plastic bottles? What are the main features?
PP bottles are non-toxic, transparent, and have certain heat resistance and impact resistance. They are generally loaded with fruit juice and shampoo. They can be hot filled (very important for fruit juice drinks). They can not be sterilized by pressure cookers, and their transparency is poor.
More common are PET, PP, PE, PC and so on.PET bottles are transparent, non-toxic, shock resistant, and resistant to high temperatures. They are usually filled with mineral water, cola, peanut oil and cosmetics. They must be filled in cold, disposable (not high temperature sterilized).
PE bottles and PP bottles are similar, toughness is better than PP, but rigidity and heat resistance are poor, solvent resistance is good, plastic soy sauce bottles seem to be PE, temporary loading a small amount of wine, kerosene will do.
PC bottles are transparent, shock resistant and high temperature resistant. They are expensive. 5 gallon pure water bottles are used at most. They can be sterilized by high temperature steam.The key depends on what you want to install, there is no corrosive, appearance requirements, and so on, decided to use what materials.
