Shopping bag, as the name suggests, is an item used for shopping. Because of its convenience, it plays an important role in people's life. As the population increases, the demand for shopping bags is also increasing. Nowadays, due to the pursuit of low-carbon and low pollution lifestyle, people have begun to use eco-friendly shopping bags. There are many ways to classify shopping bags. Let's take a look at how to classify shopping bags by material.


Plastic shopping bag

Plastic shopping bag is a kind of packaging product made of polyolefin and other materials. The polyolefin used is mainly polyethylene (PE), commonly known as soft rubber. PE mainly includes 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). Ordinary plastic shopping bags are made of polyolefin and fillers, which are not degradable and will not degrade in the wild. In order to reduce the cost, most enterprises add about 30% calcium carbonate to make large plastic shopping bags, which do not emit toxic gases when they are burned in the garbage dump.

Nonwoven shopping bag

The main material of nonwoven shopping bag is non-woven cloth made of plastic. Many people think that it is natural material, which is a misunderstanding. The common non-woven materials are polypropylene (PP) and polyethylene terephthalate (PET). PP, like PE used in plastic shopping bags, belongs to five kinds of general-purpose plastics, which can not be degraded in 50 years. For example, the common non-woven shopping bags, which we all call eco bags, are made of polypropylene fibers by special processes. In essence, polypropylene (PP) is a typical variety of plastics, which belongs to plastic bags. Therefore, nonwoven shopping bag can not be completely degraded.


In terms of cost performance, the strength of nonwoven shopping bags under the same conditions is not as good as plastic bags. It is not waterproof and its price is several times higher than that of plastic bags. It should be mentioned that it is more difficult to recycle nonwoven shopping bags made of more than two kinds of materials than ordinary plastic shopping bags with logos.



Paper shopping bag

We all know that the strength and water resistance of paper are not good. It is very difficult to package many aquatic products and bear heavy metal products. First of all, wood is the main raw material for making paper. And the world's forest resources are extremely scarce. The use of paper shopping bags is the biggest waste of environmental resources. Secondly, the process of making paper will produce a lot of water pollution. Therefore, a large number of paper shopping bags with logos are the biggest waste of environmental resources and the biggest pollution to the environment.



Cotton shopping bag

The strength of cotton shopping bag is better than that of paper shopping bag. It can be recycled for many times, but its water resistance is not very good. The advantage of cotton shopping bag is recyclable.
