Plastic bottle is a plastic container that uses polyester (PET), polyethylene (PE) and polypropylene (PP) as raw materials, adds corresponding organic solvents, and is blown, extruded, or injection molded through a plastic mold after high-temperature heating. Plastic bottle has the characteristics of not easy to break, low cost, high transparency, food grade raw materials and so on. When using plastic products, pay special attention not to contact vinegar, detergent, etc., and avoid direct sunlight, high temperature, etc., so as to avoid chemical reaction. In addition, when purchasing plastic tableware, you should choose plastic products with PE (polyethylene) or PP (polypropylene) labels, few decorative patterns, colorless and tasteless, and smooth surface.
The plastic bottle is easy to carry, not afraid of falling, has acid and alkali resistance, is easy to produce, and is also conducive to recycling. There are many ways to make polyethylene. The most common one is to polymerize ethylene at a high temperature of 200 ~ 300 ℃ and a pressure of 1000 ~ 2000 atmospheres. In polyethylene, no other substances are doped. The polyethylene prepared in this way has low density, soft texture and high stability to sunlight, air, moisture and chemical reagents, so there is no need to add stabilizers and plasticizers, while most of the stabilizers and plasticizers are toxic or highly toxic.
