What Is Difference Between Pvc and Pvdc?
Marcus Vance••4 min read
Multi-layer blister films based on PVC are often used for pharmaceutical blister packaging, whereby the PVC serves as the thermoformable backbone of the structure. Polyvinylidene chloride (PVDC) can be coated onto a PVC film to obtain very high moisture and oxygen barrier properties depending on the coating weight.
.
People also ask, what is PVDC coating?
PVDC (coated) film is mainly used in packaging of food, drugs, cosmetics, and other perishable or delicate products to extend shelf life. In comparison with many common films, PVDC coated films have superior gas and moisture barrier properties, and excellent heat sealability.
Also Know, is PVDC toxic? PVDC and the EnvironmentIt isn't PVC, but PVdC does contain chlorine and promotes concerns about end-of-life disposal through incineration where it generates a similar quantity of dioxins as PVC 1.
Then, what does PVDC stand for?
Polyvinylidene chloride or Polyvinylidene dichloride (PVDC) is a homopolymer of vinylidene chloride.
Is PVDC biodegradable?
PVDC is a form of plastic which leads to landfills and causes pollution. “Biodegradable packaging films such as PHBV provide high mechanical performance during their lifetime as original PVDC films and are completely bio-degradable after the end-of-life.
PVDC is mainly used in packaging of food, drugs, cosmetics, and other perishable or delicate products to extend shelf life. In comparison with many common films, PVDC coated films have superior gas and moisture barrier properties, and excellent heat sealability.
The polymer is obtained from the water phase as dry powder or beads, which can be melted for extrusion into plastic film. The outstanding property of PVDC is its low permeability to water vapour and gases—making it ideal for food packaging. Copolymers of vinylidene chloride and other monomers are also marketed.
