Plastic bottles are mainly made from materials such as polyethylene or polypropylene and added to a variety of organic solvents. Beverage bottles are mostly plastic products, polyethylene, polypropylene these two materials are non-toxic and tasteless, used to fill beverages and so on is very safe for the human body. But once polyethylene is subjected to high temperature or acidic corrosion will slowly dissolve, and release organic solvents, it will cause harm to the human body. Plastic bottles can melt spinning, dissolve to make unsaturated resins, or re-grain, but if re-made transparent products, it can easily be found to have poor transparency and poor light transmission particles.
Polyethylene odorless, non-toxic, feel like wax, with excellent low temperature resistance (minimum temperature of up to -70 to -100 degrees C), good chemical stability, can withstand the erosion of most acids and alkalis (not resistant to acids with oxidation properties), at room temperature insoluble in general solvents, small water absorption, electrical insulation performance is good; Chemical and mechanical) is very sensitive, poor heat resistance and aging.
The properties of polyethylene vary from species to species, depending on molecular structure and density.
Mainly used to manufacture film, containers, pipes, monofilament, wire and cable, daily necessities, and can be used as television, radar and other high-frequency insulation materials.
