Background The PGA degradation material is a plastic material with excellent biodegradability and is widely applied to the field of environmental protection. The modified plastic can be rapidly degraded in natural environment, reduces plastic pollution and meets the requirement of sustainable development. Through special molecular design, the PGA degradation material can be decomposed by microorganism action or illumination after being used and gradually converted into water and carbon dioxide, so that the ecological problem caused by the long-term existence of the traditional plastic in the environment is avoided. The material not only maintains some basic properties of plastics, such as water resistance and durability, but also gradually degrades under certain conditions, reducing long-term negative effects on the environment. The structure of a conventional film blowing wind ring is generally composed of a plurality of components including a wind flow adjusting device, a wind ring, a cooling wind flow inlet and outlet, and the like.
