POF Cross-Linked Shrink Film for Electronics 12-19μm
This POF cross-linked shrink film is made from multi-layer co-extruded polyolefin through electron beam irradiation cross-linking, forming cross-linked molecular chains. Its temperature resistance, tear resistance, and shrinkage force are superior to standard POF film. The center-fold format suits automatic packaging machines, with stable sealing and tight fit after shrinking. It is suitable for outer packaging of mobile phone boxes, earphone boxes, charger boxes, data cable boxes, smartwatch boxes, and other electronic products, as well as bundle wrapping of daily necessities, stationery, and toys. Folded width, thickness, and roll length can be customized.
