[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material. They include products made from injection molding, vacuum forming and other processes using plastic as the raw material. Plastic is a type of synthetic polymer material with plasticity. It, together with synthetic rubber and synthetic fiber, forms the three major synthetic materials that are indispensable in daily life. Specifically, plastic is a material that uses natural or synthetic resin as the main component, adds various additives, can be molded into a certain shape under certain conditions of temperature and pressure, and maintains the same shape at room temperature. Compared with metal, stone and wood, plastic products have the advantages of low cost and strong plasticity. They are widely used in the national economy.
