POF cross-linked heat shrink film is made through an irradiation cross-linking process and belongs to the category of high-end polyolefin shrink films. It features high transparency and gloss, excellent puncture resistance and heat-sealing strength, uniform shrinkage, and is less prone to loosening or tearing. It is compatible with high-speed fully automatic heat shrink equipment, resulting in a smooth and aesthetically pleasing finish. Environmentally friendly and non-toxic, it is suitable for packaging electronic products, high-end gift boxes, and food as a package, offering superior stability for packaging items with sharp edges.
