[0002] Plastic packaging refers to packaging with plastics. Plastics are a class of materials mainly made of synthetic or natural high molecular resins. After adding various additives, they have ductility at a certain temperature and pressure and can fix their shapes after cooling. Winding film is a kind of plastic packaging, and a tension adjusting device is required during the processing of winding film.

It is difficult to pull the widths of winding films with different thicknesses at the same time, which affects the processing efficiency of the winding film. For this reason, we propose a winding film tension adjusting device to solve the above problems. Summary of the Utility Model
