Shopping bag, as the name implies, is the bag used for shopping. It is a bag in which a customer can place items after they have purchased them. In life, any product in sales needs to be put into the corresponding bags, which is convenient for customers to carry.
Plastic shopping bag is a kind of packaging made of polyolefin as the main raw material and other substances. At present, polyolefins 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). In order to reduce its cost, in recent years, most enterprises have added about 30% calcium carbonate to make filled plastic shopping bags, which do not emit toxic gases when burned in the waste dump.
Ordinary plastic shopping bags - polyolefin and fillers are used as raw materials. Such plastic shopping bags do not have degradation performance and will not be degraded if abandoned in the field. This kind of plastic shopping bag has excellent recyclability and can be recycled many times. The properties of recycled materials are slightly reduced to some extent, but they can be used in shopping bags or garbage bags with low production performance requirements and not strict color requirements. At present, the key issue is whether it can be recovered.
Starch-based plastic shopping bag - this kind of shopping bag takes modified starch as the main raw material and adds a small amount of other degradable materials to improve its performance. The plastic shopping bag can be naturally degraded after being discarded in the wild. Because starch is the main raw material of starch-based plastic shopping bags, and starch comes from grain, and the price of grain is shapely increasing, countries have banned the consumption of grain to carry out industrial projects, so the prospect of such products is not good.
Plastic shopping bag degrades plastic shopping bag - this kind of shopping bag is made of fully degradable plastic and has complete degradation performance. The product can be completely degraded into small molecule microorganisms in the field without any environmental pollution. At present, this kind of plastic shopping bag is popularized abroad.
