Polyvinylidene Chloride

Polyvinylidene chloride (PVDC) resin, is usually a copolymer of vinylidene chloride with vinyl chloride or other monomers. PVDC is commonly known as Sarant. Applications and uses: Monolayer films for food wrap and medical packaging, coextruded films and sheet structures as a barrier layer in medical packaging, and packaging of foods such as fresh red meats, cheese, and sausages. Coatings are often applied to prevent specific gas transmission.

Polyvinyl chloride (PVC) is a flexible or rigid material that is chemically nonreactive. Rigid PVC is easily machined, heat formed, welded, and even solvent cemented. PVC can also be machined using standard metal working tools and finished to close tolerances and finishes without great difficulty. PVC resins are normally mixed with other additives such as impact modifiers and stabilizers, providing hundreds of PVC-based materials with a variety of engineering properties.
