PVDC (polyvinylidene chloride) | ||||||||
PVDC (polyvinylidene chloride) (C2H2Cl2)n is a highly effective barrier coating polymer that is produced by the polymerization 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 PVDC molecules that give the material its excellent barrier properties against grease, vapor and gases. This molecular structure results from the combination of salt (50-70%) and oil (30-50%). | ||||||||

Applicacions | ||||||||
The excellent barrier properties of PVDC make it ideal for use in food packaging, and it is particularly effective for products with a high fat content and strong flavors and aromas. It is often used in the packaging of confectionery products, dehydrated foods, dairy products, sausages, pâtés, meat, smoked fish and dry products such as herbs, spices, tea and coffee. | ||||||||
