Application
PVDC has a number of applications, including molding resins, extrusion resins, multilayer film, rigid barriers, containers, lacquer resin, vinylidene chloride copolymer latex and foams, resins for solvent coating, lattices for coating, and pipes for chemical processing. Polyvinylidene chloride resin is widely used in food packaging. The main reason is that it has high barrier properties. Using it to package food can effectively solve the problem of product deterioration, thereby greatly extending the shelf life of the product.
