[0002] At present, the use of touch screen electronic products is becoming more and more popular. In order to protect the touch screen from scratches and oil stains, users often choose to stick an optical protective film on the touch screen. The current substrate of the optical protective film is generally composed of a substrate layer, an adhesive layer and a peeling layer. The use of degradable materials in the substrate layer can reduce environmental pollution. The overall product is environmentally friendly and does not require subsequent recycling and treatment.

[0003] When the existing optical protective degradable film winding equipment is in use, the tension of the optical protective degradable film will change during the long-term operation of the winding equipment. Excessive or insufficient tension will affect the winding effect of the optical protective degradable film, resulting in inconsistent tightness of the rolled optical protective degradable film roll, thereby resulting in poor winding quality of the optical protective degradable film.
