The raw material of non-woven fabric is polypropylene, and the raw material of plastic bags is polyethylene. The chemical molecular structure of polyethylene is quite Strong stability and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; and the chemical structure of polypropylene is not strong, and the molecular chain can be easily broken, which can be effectively degraded and is in a non-toxic form Entering the next environmental cycle, a non-woven bag can be completely decomposed within 90 days.　　Quanzhou Nonwovens Co., Ltd. is a professional manufacturer of environmentally friendly nonwovens with a complete and scientific quality management system. Mainly produce composite non-woven fabrics, polyester non-woven fabrics, pet non-woven fabrics and various non-woven fabric products. It is becoming more and more popular in the market.
