True cross-linked film particularly irradiation cross-linked shrink film undergoes a measurable change in molecular architecture.Chemical cross-linking uses peroxide-based or silane-based systems blended into the resin before or during extrusion.
PCR Cross-Linked Shrink Film. Cross-linking technology strengthens the polymer chains within the film, making it more resistant to tearing, puncturing, and damage during handling and transportation.

Cross-linked pof shrink film (CX-POF) is a special type of polymer film that is crosslinked to increase its thermal stability and mechanical properties while retaining its excellent shrinkage properties.

Cross-Linked Heat Shrink Tube ProductionMaterial Extrusion: Base polymer (typically polyolefin) is extruded into tube formExpansion Process: Cross-linked tubes are heated and mechanically expanded
