Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for stretch wrap film production, specifically a dust removal device for the surface of stretch wrap film. Background Technology

[0002] Stretch wrap film is made from imported resin and advanced cast film extrusion technology. At room temperature, the film is mechanically stretched or manually to create deformation force that tightly wraps goods, facilitating transportation and storage. Stretch wrap film is widely used for bundling and packaging chemical raw materials, fertilizers, food, and light textile products.

[0003] After the stretch wrap film is injection molded, some impurities will be adsorbed on the surface of the stretch wrap film during the tensioning and winding process. If they are not removed in time, they will affect the quality of the stretch wrap film during the continued winding process. Utility Model Content
