General Materials For Plastic Boxes

Plastic is a synthetic or natural polymer resin as the main material. After adding various additives, it has ductility under certain temperature and pressure, and can fix its shape after cooling. The process in which natural or synthetic polymer resin molecules are in a molten state and the molecules of auxiliary agents are evenly distributed around it is called plasticization. This process has been reached and it is called plasticized. It has not 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%, plastic 25%, metal 25%, and glass 15%.
