Degradable Plastic Shopping Bags - These shopping bags are made from fully degradable plastics and have complete degradation properties. The product can be completely degraded into small molecular microorganisms in the wild without any environmental pollution. Currently, such plastic shopping bags are promoted abroad. According to the specific composition of fully degradable plastics, they can be divided into the following three categories:
(1) PLA, PHA biodegradable plastics synthesized by bio-fermentation using natural starch as raw materials consume a large amount of food, so the development space is limited.
(2) Aliphatic polycarbonate (APC)-based degradable plastics synthesized from carbon dioxide, which utilizes the carbon dioxide, an industrial by-product that is currently being screamed by everyone, without consuming food and reducing carbide emissions. To eliminate the "El Niño" phenomenon caused by the greenhouse gas effect, and to achieve two goals, the market prospect is broad.
(3) The complete degradation product of non-starch degrading agent added to ordinary plastics is currently in the stage of industrialization, such as reliable degradation performance and promising future.
