Material Of Plastic Box

Plastics are mainly made of synthetic or natural polymer resins. A type of material that exhibits ductility at a certain temperature and pressure after adding various additives, and can fix its shape after cooling. The process of natural or synthetic polymer resin molecules in a molten state with uniformly distributed auxiliary molecules around them is called plasticization. If this process has been achieved, it is called plasticization. If it has not yet been achieved, it is considered that it has not been plasticized. Plastic packaging is one of the four major materials in the packaging industry: paper and cardboard account for 30%, plastic accounts for 25%, metal accounts for 25%, and glass accounts for 15%.
