poly(vinylidene chloride)

polymer

Poly(vinylidene chloride), commonly known as PVDC, is a thermoplastic polymer characterized by a linear backbone of alternating carbon and chlorine atoms, offering exceptional chemical resistance and low permeability. It is widely used in flexible packaging films—particularly for food, pharmaceuticals, and moisture-sensitive products—where its superior barrier properties against oxygen and water vapor extend shelf life and maintain product integrity. PVDC is valued in industrial applications as a coating or film layer in multi-layer structures because it outperforms standard polyethylene and polypropylene in gas-barrier performance, though it is gradually being supplemented by newer high-barrier alternatives in some markets.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
