Material classification of plastic shopping bags:
Plastic shopping bags are packaging materials made of polyolefin as the main raw material and appropriate addition of other substances. The polyolefin used is mainly polyethylene (PE), commonly known as soft rubber. The main products include low-density polyethylene or high-pressure polyethylene (LDPE), high-density polyethylene or low-pressure polyethylene (HDPE), linear low-density polyethylene ( LLDPE) and metallocene polyethylene (mLLDPE) four categories. In order to reduce its cost, most companies add about 30% calcium carbonate to make filled plastic shopping bags. Such plastic shopping bags do not emit toxic gases when incinerated in the garbage dump. The national plastic shopping bag standard just released divides plastic shopping bags into the following three categories:
Ordinary plastic shopping bags-using polyolefin and fillers as raw materials, this type of plastic shopping bags have no degradability, and will not degrade when thrown away in the wild. Such plastic shopping bags have excellent recyclability and can be recycled and reused many times. The performance of recycled materials is slightly reduced to varying degrees, but it can be used for shopping bags or garbage bags with low production performance and color requirements. The key question is whether it can be recovered.
Starch-based plastic shopping bags-this type of shopping bags use modified starch as the main raw material, and a small amount of other degradable materials are appropriately added to improve its performance. The plastic shopping bag can be naturally degraded after being discarded in the wild.
Degradable plastic shopping bags-This type of shopping bag is produced from completely degradable plastics and has complete degradation properties. Abandoned in the wild, the product can be completely degraded into small molecule microorganisms without any environmental pollution. Such plastic shopping bags are promoted abroad. According to the specific composition of completely degradable plastics, they can be divided into the following three categories:
(1) PLA and PHA biodegradable plastics synthesized through biological fermentation with natural starch as raw materials need to consume a large amount of food, so the development space is limited.
(2) Aliphatic polycarbonate (APC) degradable plastics synthesized with carbon dioxide as raw materials, which use industrial by-product carbon dioxide as the raw material, which not only consumes food, but also reduces the emission of carbides. Elimination of global warming caused by greenhouse gases will kill two birds with one stone, so the market prospects are broad.
(3) Completely degradable products with non-starch degradation agents added to ordinary plastics are in the industrialization stage. If the degradation performance is reliable, they have a promising future.
