[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles widely use polyester, polyethylene, and polypropylene as raw materials, add corresponding organic solvents, and are heated at high temperatures. They are blow molded, extruded, or injection molded through plastic molds. They are mainly used for liquid or solid disposable plastic packaging containers such as beverages, foods, pickles, honey, dried fruits, edible oils, and agricultural and veterinary drugs. Plastic bottles have the characteristics of being not easy to break, low cost, high transparency, and food-grade raw materials.
