    PVDC (Polyvinylidene Chloride) (C2H2Cl2)n is a highly effective barrier coating polymer that is produced by the polymerisation of a vinylidene chloride monomer with other monomers such as acrylic esters and unsaturated carboxyl groups. It is the chemistry, density and symmetry of the molecules in PVDC that give the material its excellent barrier properties against fat, vapor and gases. This molecular structure results from the combination of salt (50-70%) and oil (30-50%).
