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 the natural or synthetic polymer resin molecules in the molten state, and the uniform distribution of the auxiliary molecules around the process is called plasticization. This process has been reached, which has been plasticized, 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%, plastics for 25%, metal for 25%, and glass for 15%.

       The plastic box is made of PVC/PET/PP/PS, such as transparent folding box, cylinder, heaven and earth cover box, hand bag, elevator hanging piece and other related plastic products, which can achieve UV offset printing, silk screen printing and bronzing. / Silver, frosting and other printing effects, with increased user experience, packaging durable, moisture-proof, waterproof, high toughness, strong transport safety performance, improve product grades and so on.
