Non-woven shopping bags are non-woven fabrics made of plastic. Many people think that calling cloth is a natural material. It is actually a misunderstanding. The commonly used non-woven materials are polypropylene (PP, commonly known as polypropylene) or polyethylene terephthalate (PET for short, commonly known as polyester), and the raw material for plastic bags is polyethylene. Although the two materials have similar names, , but the chemical structure is very different. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade. Therefore, the plastic bag needs 300 years to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken and can be effectively degraded. , And in the non-toxic form into the next environmental cycle, a non-woven shopping bag can be completely decomposed within 90 days. In essence, polypropylene (PP) is a typical plastic material. After the disposal, the degree of pollution to the environment is only 10% of the plastic bag.
Non-woven bags, on December 31, 2007, the government formally promulgated the "non-woven order" non-woven bags to quickly popularize, but found many problems with the current use situation:
1. In order to reduce the cost, printing inks on non-woven fabric bags is harmful to the human body. The question is whether the printing of environmental protection bags is environmentally friendly. I once said in other topics.
2. The large number of non-woven bags is used to make some non-woven bags at home faster than plastic bags. It is not a waste of resources.
3. The non-woven fabric is not environmentally friendly because it is of the same composition as the plastic bag. Polypropylene and polyethylene are very difficult to degrade. The reason why it is promoted is that it is environmentally friendly because it is thinner than plastic. Bag height and toughness are good for repeated use and can be reused. This kind of cloth is suitable for companies that are not very strong. They also want to promote environmental protection as a substitute for plastic bags and paper bags. It is also practical to promote free distribution at exhibitions and events. Of course, The effect is proportional to the style and quality of your own production. If you are too bad, be careful to use it as a garbage bag.
