[0002] During the use of the existing high-transparency compression film, when it is segmented and packaged and shrunk, the cutting operation of the shrink film is rather cumbersome, lacking a corresponding structure for quickly cutting it, which affects the use efficiency of the high-transparency shrink film; when it is necessary to continuously use the shrink film for hot air packaging, there is a lack of a structure for continuously, quickly and stably placing the shrink film to facilitate the continuous use of the high-transparency shrink film for rapid packaging.

[0003] Chinese Patent with publication number CN208308767U discloses a high-performance shrink film, including a shrink film body. The shrink film body includes a comprehensive elastic composite layer, a high-permeability film layer and a glue-resistant high-temperature bonding layer. The high-permeability film layer is provided below the comprehensive elastic composite layer, and the glue-resistant high-temperature bonding layer is provided below the high-permeability film layer. The overall weight ratio of the high-permeability film layer is set to 35 - 55%, the weight ratio of the comprehensive elastic composite layer is set to 15 - 25%, and the weight ratio of the glue-resistant high-temperature bonding layer is set to 10 - 20%. The thickness of the comprehensive elastic composite layer is controlled within 4 - 10um, and the thickness of the glue-resistant high-temperature bonding layer is controlled within 6 - 14um. The shrink film body made by the utility model has very good low-temperature shrinkage effect, its shrinkage temperature is almost the same as that of the PVC shrink film, and at the same time, the shrinkage speed is very fast, the sealing strength is good, and the application range is relatively wide.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model
