Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, staple fibers or filaments to form new fiber products with soft, breathable and planar structures through various fiber mesh forming methods and consolidation technologies. Compared with traditional plastic bags, non-woven bags have the advantages of low price, good quality, environmental protection and practicality, wide application and outstanding advertising position. It is suitable for all kinds of business activities and exhibition fairs. It is an ideal advertising promotion gift for enterprises and institutions. The raw material of non-woven bag is polypropylene, while the raw material of plastic bag is polyethylene. Although the two substances have similar names, they are far from each other in chemical structure. The chemical molecular structure of Polyethylene has strong stability and is extremely difficult to degrade, so it takes 300 for plastic bags to decompose; However, the chemical structure of polypropylene is not firm, and the molecular chain can be easily broken, thus effectively degrading, and entering the next environmental cycle in a non-toxic form, A non-woven bag can be completely decomposed within 90 days. Non-woven fabrics are products that do not require a textile process and are made into non-woven fabrics, also known as non-woven fabrics. Because it only needs to orient or randomly support the textile staple fibers or filaments to form a web structure, and then it can be made by mechanical, thermal or chemical reinforcement. Non-woven bags are mostly made of spunbonded non-woven fabrics. Simply put, non-woven fabrics are not interwoven and woven together by one yarn, but the fibers are directly bonded together by physical methods, so, when you get the sticky weight in your clothes, you will find that you can't get a thread. Non-woven fabric breaks through the traditional textile principle and has the characteristics of short technological process, fast production speed, high output, low cost, wide application and many sources of raw materials. Laminated non-woven fabric bag, the product adopts tape casting method, is firmly compounded, does not glue in the compounding process, has soft hand feeling, no plastic feeling and no skin irritation, and is suitable for disposable medical sheets, bed sheets, surgical gowns and isolation suits, production of protective clothing, shoe covers, and other sanitary protective equipment; The bag made of this kind of cloth is called a laminated non-woven bag.
