Plastic packaging is made of plastic materials, such as packaging boxes. Plastic is a synthetic or natural polymer resin as the main material. After adding a variety of additives, at a certain temperature and pressure with ductility, cooling can be fixed its shape of a class of materials.
Natural or synthetic polymer resin molecules in the melting state, and around the uniform distribution of auxiliary molecules process called plasticizing, has reached the process called has been plasticizing, has not yet reached, is considered not plasticizing. Plastic packaging is one of the four materials in the packaging industry: paper and paperboard accounted for 30%, plastic accounted for 25%, metal accounted for 25%, glass accounted for 15%.Side Seal Bag
