A winding film machine is a packaging equipment used for producing stretch films with adhesive properties. It is mainly used to co extrude resin materials such as linear low-density polyethylene (LLDPE) into single-layer or double-layer adhesive winding films through co extrusion technology. The film produced by this equipment has high tensile strength, puncture resistance, and shrinkage memory characteristics, which are suitable for bulk cargo pallet packaging. It can stabilize the overall structure and prevent scattering, dust pollution, and moisture intrusion during transportation. According to functional differences, common types include:
