[0002] Degradable plastics are generally considered to be plastics that can be decomposed into low molecular substances by sunlight radiation or microorganisms in the soil. In addition to degradability, they should also have easy processing and performance to meet the use requirements. The harmful effect of sunlight on polymer materials is the combined effect of ultraviolet light and oxygen, so it is called photo-oxidative degradation. For example, photo-oxidation often causes chain scission or crosslinking of polyolefins, accompanied by the formation of some oxygen-containing functional groups such as ketones, carboxylic acids, peroxides and alcohols.

[0003] In the processing of degradable plastics, in order to improve the transportation and collection of plastics, they are usually wound into a bundle of state, thereby improving the transportation efficiency and storage effect of plastics. In the winding process of the prior art, when the personnel cut the edge of the plastic, the plastic edge is easily curled and cannot be quickly cut, thereby affecting the later use.
