What is a shopping bag?
Shopping bags, as the name suggests, are bags used for shopping. The shopping bags currently available on the market mainly include: plastic shopping bags, non-woven shopping bags, paper shopping bags, and cotton and linen shopping bags.
Classification of 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.
