Description

Technical Field

[0001] This utility model relates to the field of heat shrink film technology, specifically a longitudinal sealing structure for heat shrink film. Background Technology

[0002] Heat shrink film is a type of shrink film used in the sale and transportation of various products. Its main function is to stabilize, cover, and protect the products. The shrink film must have high puncture resistance, good shrinkage, and a certain shrinkage stress. During the shrinkage process, the film must not produce holes. Since the shrink film is often used outdoors, UV stabilizers need to be added. The heat shrink film needs to be longitudinally sealed during the production process, but the existing longitudinal sealing structure cannot automatically cut the heat shrink film, which causes inconvenience to users. Therefore, we propose a longitudinal sealing structure for heat shrink film. Utility Model Content
