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. The commonly used raw material of non-woven fabric is polypropylene (PP in English, commonly known as polypropylene) or polyethylene terephthalate (PET in English, commonly known as polyester), and the raw material of plastic bags is polyethylene, although the names of the two substances are similar , But the chemical structure is far different. The chemical molecular structure of polyethylene is very 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 easily be broken, which 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 type of plastic, and the 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 issued a "plastic ban" non-woven bags are quickly popularized, but many problems have also been found in their use:
1. In order to reduce costs, many companies print patterns on non-woven bags, which are harmful to human health.
2. The low price of non-woven bags has led to the mass distribution of non-woven bags, making the number of non-woven bags in some homes almost surpassed that of plastic bags, which is a waste of resources.
3. Non-woven fabrics are not environmentally friendly in terms of texture, because they are made of polypropylene and polyethylene, which are the same as plastic bags, which are difficult to degrade. The reason for promoting it is that it is environmentally friendly because its thickness is higher than that of plastic bags. , Strong toughness is conducive to repeated use, it can be recycled and reused. This kind of cloth bag is suitable for environmental protection as a substitute for plastic bags and paper bags. It is also very practical for free distribution at exhibitions and events. Of course, the effect is that it is in line with the style and quality of self-made In proportion, if the price of non-woven eco-friendly bags is low and the quality is too poor, be careful when others use them as garbage bags.
