Background

The plastic bottle is mainly made of polyethylene or polypropylene and other materials with a plurality of organic solvents. The plastic bottle widely uses Polyester (PET), Polyethylene (PE) and polypropylene (PP) as raw materials, and is a plastic container which is added with a corresponding organic solvent, heated at high temperature, blown, extruded and blown or injection molded by a plastic mold. The plastic bottle is mainly used for liquid or solid disposable plastic packaging containers of beverages, foods, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs and the like. The plastic bottle has the characteristics of low breakage probability, low cost, high transparency, food-grade raw materials and the like.
