What should I do if the PVC heat shrinkable film is aging?

During the processing, storage and use of PVC heat shrinkable film, under the action of light, heat and oxygen, aging phenomena such as fading, brittleness or cracking will occur. PVC heat shrinkable film must be added with stabilizers to delay and prevent the occurrence of aging.

Those used to prevent thermal aging are also called heat stabilizers, and those used to prevent oxidative aging are called antioxidants. The substances that prevent light aging are called light stabilizers, and they are collectively called stabilizers. Today's PVC heat shrinkable film stabilizer is methyl tin heat stabilizer (181 for short), which is very effective for calendering, extrusion, injection molding and blow molding of rigid polyethylene (PVC).

The effect of PVC heat shrinkable film is getting more and more beautiful, and the functionality is getting stronger. With the improvement of the quality of life and the diversification of packaging films, the requirements for shrink film are also getting higher and higher. For the sales and transportation of various products, its main function is to stabilize, cover and protect the product. It also has high puncture resistance, good shrinkage and corresponding shrinkage stress.
