Plastic bottles are made of polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials. After adding corresponding organic solvents, they are heated at high temperature, and then are blown, squeezed, or injection molded through plastic molds. plastic containers. Plastic bottles have the characteristics of being unbreakable, low cost, high transparency, and food-grade raw materials. When using plastic products, pay special attention to avoid contact with vinegar, detergents, etc., avoid direct sunlight, high temperature, etc., to avoid chemical reactions. In addition, when you buy plastic tableware, you should choose plastic products with PE (polyethylene) or PP (polypropylene) labels, few decorative patterns, colorless and odorless, and smooth surface.
