Principle of non-woven bags

Nonwoven fabric is a kind of nonwoven fabric, which directly uses polymer slices, staple fibers or filaments through a variety of fiber network forming methods and cementing technology to form a new type of fiber products with soft, breathable and flat structure. Advantages of non-woven bags compared to traditional plastic bags: non-woven bags are inexpensive, environmentally friendly and practical, widely used, with prominent advertising position. Suitable for all kinds of business activities and exhibitions and trade fairs, is the ideal advertising and promotional gifts for enterprises and institutions.
The raw material of non-woven bags is polypropylene, and the raw material of plastic bags is polyethylene, two substances, although the name is similar, but in the chemical structure is very different. Polyethylene's chemical molecular structure has a strong stability, extremely difficult to degrade, so plastic bags need 300 years to decompose; and polypropylene's chemical structure is not strong, the molecular chain can be easily broken, which can be effectively degraded, and in the non-toxic form to enter the next step of the environmental cycle, a non-woven bag in 90 days can be completely decomposed.
Nonwoven is a product that does not require a textile process and is made to look like a cloth, also known as non-woven fabric. Because it is only textile staple fibers or filaments for directional or random support columns, the formation of fiber network structure, and then use mechanical, thermal bonding or chemical methods such as reinforcement can be made. Most of the nonwoven bags are made of spunbond nonwoven fabric.
Simply put: nonwoven fabrics are not interwoven and knitted together by one yarn after another, but the fibers are directly bonded together by physical methods, so when you get the sticky claim in your clothes, you will find that it is not possible to draw a single thread. Nonwoven fabric breaks through the traditional textile principle, and has a short process, fast production speed, high yield, low cost, wide range of uses, raw material sources and other characteristics.
Compound film non-woven bags, the product adopts casting method, composite firm, non-stick glue in the process of composite, soft touch, no plastic feeling, no skin irritation, suitable for disposable medical center sheet, bed sheet, surgical gowns, isolation clothing, protective clothing, shoe covers, such as the production of sanitary and protective supplies; the bags made of this kind of cloth are called compound film non-woven bags.
