[0002] Plastic products are life, industrial and other products processed from plastic as the main raw material, including all processes such as injection molding, blister, drilling and other products made of plastic as raw material. Plastic is a kind of synthetic high polymer material with plasticity. It, together with synthetic rubber and synthetic fiber, forms the three indispensable synthetic materials in daily life. Specifically, plastic is a material that can be molded into a certain shape under certain temperature and pressure conditions by using natural or synthetic resin as the main component and adding various additives, and keeping the shape unchanged at room temperature.
