Aluminum Shrink Film

PVC heat shrink film, also known as polyvinyl chloride heat shrink film. PVC heat shrink film is made by mixing PVC resin with more than ten auxiliary materials using ethylene method, followed by secondary inflation and cooling with a water ring. Its characteristics are good transparency, easy shrinkage, high strength, and the shrinkage rate can be freely adjusted according to user needs. Colors can be added according to customer requirements to make various colors of films. PVC shrink film is used in the sales and transportation process of various products. Its main function is to stabilize, cover, and protect the product from scratches and scattering. Heat shrink film must have high puncture resistance, good shrinkage, and a certain degree of shrinkage stress. During the shrinkage process, the film should not produce pores, and the temperature should not be too high during shrinkage, otherwise the surface temperature of the film will be too high, causing it to rupture.
