Non-woven shopping bags are
non-woven fabrics made of plastic. Many people think that cloth is a natural material, but it is actually a misunderstanding. Commonly used non-woven raw materials are polypropylene (PP, commonly known as polypropylene) or polyethylene terephthalate (PET, commonly known as polyester). The raw material of plastic bags is polyethylene. Although the names of the two substances are similar , but the chemical structures are quite different. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken, so it can be effectively degraded , and enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. In essence, polypropylene (PP) is a typical variety of plastics, and its pollution to the environment after disposal is only 10% of that of plastic bags. The price of non-woven bags also determines its quality.
The government officially promulgated the "plastic ban" non-woven bags, which were quickly popularized, but many problems were also found in the use situation:
1. In order to reduce costs, many companies print patterns on non-woven bags, which is very harmful to the human body.
2. The price of non-woven bags is low, which makes the large-scale distribution of non-woven bags, so that the number of non-woven bags in some households almost exceeds that of plastic bags. If they are not used, it is a waste of resources.
3. Non-woven fabrics are not environmentally friendly in terms of texture, because they are the same as plastic bags and are made of polypropylene and polyethylene, which are difficult to degrade. The reason why it is popularized and said to be environmentally friendly is because its thickness is higher than that of plastic bags. , Strong toughness is conducive to repeated use, and can be recycled and reused. This kind of cloth bag is suitable for environmental protection as a substitute for the former plastic bags and paper bags. It is also very practical for free distribution at exhibitions and events. Of course, the effect is consistent with the style and quality of its own production. Proportional, if the price of the non-woven bag is low and the quality is too poor, be careful that others use it as a garbage bag.
