What Is Non Woven Bag

Non woven bag is a kind of environment-friendly product. It is tough and durable, beautiful in shape, good in air permeability, reusable and washable. It can be used for silk screen advertising, shipping mark and long in use.

The product is made of non-woven fabric, which is a new generation of environmental protection material. It is moisture-proof, breathable, flexible, light, non combustion supporting, easy to decompose, non-toxic and non irritating, rich in color, low in price and recyclable. The material can decompose naturally in 90 days outside and has a service life of up to 5 years in the room. It is non-toxic, tasteless and free of any leftover substances during combustion, so as not to pollute the environment.

Principle

Non-woven fabric is a kind of cloth produced not through weaving. It is a new type of fiber product with soft, breathable and plane structure, which is directly formed by polymer chips, short fibers or filaments through various fiber mesh forming methods and consolidation techniques. Compared with traditional plastic bags, non-woven bags have the advantages of low price, good quality, environmental protection, wide application and prominent advertising position. Suitable for all kinds of business activities and exhibitions, 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 names of the two substances are similar, their chemical structures are far from each other. The chemical molecular structure of polyethylene is very stable and very hard to degrade, so it usually takes 300 years for the plastic bag to decompose; the chemical structure of polypropylene is not solid, and the molecular chain is easy to break, so it can be effectively degraded, and in the non-toxic form into the next environmental cycle, a non-woven bag can decompose completely in 90 days.

Non woven fabric is a kind of cloth-like product which does not need the spinning process, also called non-spun fabric, because it only needs to carry out directional or random bracing of textile short fiber or filament to form a fiber net structure, and then it can be made by mechanical, thermal bonding or chemical reinforcement methods. Most of the non-woven bags are made of spunbond.

In a word, non-woven fabric is not interweaved and knitted by one yarn, but the fibers are directly bonded together by physical methods. Therefore, when you get the scale in your clothes, you will find that there is no thread out. Nonwovens break through the traditional textile principle, and have the characteristics of short technological process, fast production speed, high output, low cost, wide use and many sources of raw materials.

Compound film non-woven cloth bag, the product adopts the casting method, the compound is firm, during the compound process, it is not sticky, with soft sensation. It has no plastic sensation or skin irritation. It is suitable for the production of disposable medical middle sheet, bedspread, surgical clothing, isolation clothing, protective clothing, shoe cover, and other health protection products. The bag made of this kind of cloth is called compound film non-woven cloth bag.
