[0002] The unique heat shrinkage performance of the rust-proof heat-shrinkable composite film can fit metal materials and packaged equipment. The tight packaging can replace wooden boxes, cartons, welded metal frames and other outer packaging boxes. The packaging can be customized according to the size of the product. It is easy to operate, reduces packaging costs, and is economical and efficient. The Chinese utility model authorized patent CN202122020943.9 discloses a heat-insulating composite film with anti-rust function. The composite film is a thin film material disclosed in the manufacturing technology principle;

[0003] Composite film packaging is applied to the outside of some wooden boxes, cartons, welded metal frames and other items. During transportation, the composite film will be subjected to external friction such as collision with splashing stones. Although it has certain protection, the composite film will become twisted and deformed due to bumps, vibrations and inertial displacement of the items during transportation, and may even be torn and damaged. For this reason, we propose a tensile composite film. Utility Model Content
