Plastic is made of synthetic or natural polymer resin as the main material. Add a variety of additives, at a certain temperature and pressure with ductility, cooling can be fixed after the shape of a class of materials. Natural or synthetic polymer resin molecules in the molten state, and the surrounding uniform distribution of additives molecules called plastic process, has reached the process that has been plasticized, has not yet reached, is considered not yet plasticized. Plastic packaging is one of the four major packaging materials: paper and paperboard accounted for 30%, plastic accounted for 25%, metal accounted for 25%, glass accounted for 15%.

The plastic packaging through a variety of printing equipment, printed on the pattern of the process is plastic color packaging.
