The plastic bottle is made of polyester (PET), polyethylene (PE) and polypropylene (PP). After adding the corresponding organic solvent, it is heated at a high temperature and then blown, blown, or injection molded through a plastic mold. Plastic container. Plastic bottles are characterized by being difficult to break, low cost, high transparency, and food grade raw materials.
Special care should be taken when using plastic products. Do not touch vinegar, detergent, etc., and avoid direct sunlight, high temperature, etc., to avoid chemical reactions. In addition, when purchasing plastic tableware, you should select plastic products with PE (polyethylene) or PP (polypropylene) labeling, less decorative patterns, colorless, odorless, and smooth surface.
There are many ways to make polyethylene, the most common of which is the polymerization of ethylene at a high temperature of 200 to 300 ° C and a pressure of 1000 to 2000 atmospheres. In polyethylene, no other substances are doped. The polyethylene thus obtained has a low density and a soft texture, and has high stability to sunlight, air, moisture and chemical agents, so that no stabilizer or plasticizer is required, and most of the stabilizers and plasticizers are Toxic or highly toxic.
The plastic bottle is easy to carry, not afraid of falling, has acid and alkali resistance, is convenient to produce, and is also convenient for recycling.
