PVC material is one of the most widely used plastic source materials for transparent plastic packaging. PVC material is a non-crystalline material. In practice, PVC materials often include stabilizers, lubricants, auxiliary processing agents, colorants, impact modifiers, and other additives. PVC material has non-flammability, high strength, weatherability and excellent geometric stability. PVC is very resistant to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid, and is not suitable for applications in contact with aromatic hydrocarbons and chlorinated hydrocarbons.
