Plastic packaging is a packaging box made of plastic. Plastics are based on synthetic or natural polymer resins. After adding various additives, it has ductility under certain temperature and pressure, and can fix a kind of material of its shape after cooling.
The process of natural or synthetic polymer resin molecules in a molten state and uniform distribution of auxiliary molecules around them is called plasticization. This process has been achieved, which has been plasticized, has not yet been reached, and is considered to have not been plasticized. Plastic packaging is one of the four major materials in the packaging industry: paper and cardboard account for 30%, plastics for 25%, metal for 25%, and glass for 15%.
