Polyvinylidene chloride is made from ethylene and chloride,and approximately 70% of the chlorine used is derived from sodium chloride. In this sense ,it can be said that PVDC is an ideal plastic for petroleum resource conservation. As PVDC resins are high-density hydrophobic polymers,they provide an excellent barrier to oxygen,water vapor and aromas. They also have […]

“PVDC coated films” is a general term for films coated with a thin layer (1 –3 μm) of PVDC. They are used in a variety of applications as packaging materials that provide gas barrier properties in addition to the properties of their base films. Gas Barrier Properties Unaffected By Humidity PVDC coated films maintain stable

The Coating Film To Meet The Requirements Of Food Packaging Traditional composite processing can produce two or more films of both the performance of multi-functional composite film. However, the object must be a composite film processing, and PVDC, PVA and other functional materials should not be made into film (process, high costs, technical difficulties), and
