PET plastic bottles are not only widely used to pack carbonated beverages, drinking water, fruit juice, enzymes and tea drinks, but also widely used in food, chemical, pharmaceutical packaging and many other fields. PET plastics are widely used in the packaging field, whether it is packaging film, rolls, or beer bottles, all use PET plastics. But when these materials are abandoned, they are faced with the problem of how to deal with them. China produces tens of billions of PET plastic bottles every year, and more than 500,000 tons of PET will be used in the manufacture of PET plastic bottles every year.
PET plastic bottles are more suitable for packaging and health products.
Polyethylene terephthalate is the most important kind of thermoplastic polyester. Polythylene terephthalate is abbreviated as PET or PETP (hereinafter referred to as PET), commonly known as polyester resin. It is terephthalic acid and ethylene glycol polycondensation, with PBT collectively known as thermoplastic polyester, or saturated polyester. PET is a highly crystalline white or yellowish polymer with smooth and glossy surface. It has good creep resistance, fatigue resistance, friction resistance and dimensional stability, small wear and high hardness, with the greatest toughness of thermoplastic; good electrical insulation, less affected by temperature, but poor corona resistance. Non-toxic, weather-resistant, anti-chemical stability, low water absorption, weak acid resistance and organic solvents.
