PVC zipper bags are made of PVC material. PVC materials are often used in practical use with stabilizers, lubricants, auxiliary process agents, color materials, anti-impact agents and other additives. It has non-flammability, high strength, gas resistance and good geometrical stability. PVC has strong resistance to oxidants, reducing agents, and strong acids. However, it can be corroded by concentrated acid such as concentrated sulfuric acid and concentrated nitric acid and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

The melting temperature of PVC during processing is a very important factor.
