Shopping bags, as the name implies, are the bags used for shopping. Currently, the shopping bags available on the market mainly include: plastic shopping bags from Yingkou shopping bags, non-woven shopping bags, paper shopping bags, cotton and linen shopping bags, etc.

In today's society, the pursuit of low-carbon and low-pollution lifestyles, as the population increases, the demand for shopping bags is also increasing. In view of the large amount of pollution, eco-friendly shopping bags have been launched. The plastic shopping bag is a packaging material made of polyolefin as a main raw material and appropriately added with other substances. The polyolefins used are 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) are four major categories. In order to reduce their cost, most companies add about 30% calcium carbonate to make plastic shopping bags. These plastic shopping bags do not emit toxic gases when they are burned in the garbage dump.
