The full name of POF heat shrink film is multi-layer co-extruded polyolefin heat shrink film. POF shrink film uses linear low density polyethylene as the middle layer (LLDPE) and copolypropylene (pp) as the inner and outer layers. Extruded, and then processed by special processes such as die forming and film bubble inflation.
Heat shrink film is used for the sale and transportation of a variety of products, the main function is to stabilize, cover and protect the product. The shrinkfilm must have high puncture resistance, good shrinkage and certain shrinkage stress. During shrinkage, the film does not create holes. Since the shrink film is often used outdoors, UV anti-UV agents need to be added.
What is POF shrink film
POF shrink film is a strong, highly transparent, two-way shrinkable heat shrink film. The shrinkage rate is stable and balanced during the packaging process.
