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

The plastic box is made of PVC/PET/PP/PS and other related plastic products such as transparent folding box, cylinder, heaven and earth cover box, hand bag, hanging card hanging piece, etc. It can be used for UV offset printing, silk screen printing and hot stamping. / Silver, frosted and other printing effects, with the increase of user experience, packaging permanent and durable, moisture-proof, waterproof, high toughness, transport safety performance, improve product quality and other characteristics.
