The material characteristics and characteristics of non-woven bags for foreign trade are as follows:

Non-woven fabric is a kind of non-woven fabric. It uses high polymer chips, short fibers or filaments to air-fiber or mechanically mesh the fiber, and then it is strengthened by hydroentanglement, needle punching, or hot rolling, and finally finishing. Formed non-woven cloth. The new type of fiber products with soft, breathable and flat structure has the advantages of not producing fiber shavings, strong, durable, silky soft, and also a kind of reinforcing material. It also has a cotton feel. Compared with cotton, non-woven Cloth bags are easy to shape and cheap to build.

Material characteristics of foreign trade non-woven bags:

1. Light weight: polypropylene resin is the main raw material for production, the proportion is only 0.9, only three-fifths of cotton, fluffy and feel good.

2, soft: composed of fine fibers (2-3D) light spot hot melt bonding molding. The finished product is moderately soft and comfortable.

3. Water repellency and breathability: Polypropylene chips do not absorb water, and the moisture content is zero. The finished product has good water repellency. It is composed of 100% fiber with porosity, good air permeability, easy to keep the fabric dry and easy to wash.

4. Non-toxic and non-irritating: The product is produced according to FDA food-grade raw materials, contains no other chemical ingredients, stable performance, non-toxic, non-odor, and does not irritate the skin.

5. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, and it does not worm, and can isolate the erosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and finished products do not affect the strength due to erosion.

6, antibacterial. The product is water-extracting, does not mold, and can isolate the erosion of bacteria and insects in the liquid, and does not mold.

7. Good physical properties. It is made of polypropylene spun directly into a net for thermal bonding. The strength of the product is better than that of ordinary staple fiber products. The strength is non-directional and the strength in the vertical and horizontal directions is similar.

8. In terms of environmental protection, the raw material of most non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the two materials have similar names, they have far different chemical structures. The chemical molecular structure of polyethylene has considerable stability and is extremely difficult to degrade, so plastic bags take 300 years to decompose; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken, which can effectively degrade. , And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed in 90 days. Moreover, non-woven shopping bags can be reused more than 10 times, and the pollution degree to the environment after disposal is only 10% of that of plastic bags.
