Raw Materials Of Non-woven Bags

The raw material of the non-woven bag is polypropylene, and the raw material of the plastic bag is polyethylene. Although the two substances have similar names, they are very different in chemical structure. The chemical molecular structure of polyethylene is quite stable and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can be easily broken, so it can be effectively degraded , and enter the next environmental cycle in a non-toxic form, a non-woven bag can be completely decomposed within 90 days.

Non-woven fabrics are non-woven products that do not require weaving process, and are also called non-woven fabrics. Because it only needs to orient or randomly align the textile staple fibers or filaments to form a web structure, and then use mechanical, thermal bonding or chemical methods to reinforce it. Most non-woven bags are made of spunbond non-woven fabrics.

To put it simply, the non-woven fabric is not interwoven and knitted together by yarns one by one, but the fibers are directly bonded together by physical methods. Therefore, when you get the sticky weight in your clothes, When you do, you will find that you can't pull out a single thread. Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and many sources of raw materials.

Laminated non-woven bag, the product adopts the casting method, the compound is firm, non-adhesive during the compounding process, soft to the touch, no plastic feeling, no skin irritation, suitable for disposable medical singles, bed sheets, surgical gowns, The production of isolation clothing, protective clothing, shoe covers, and other sanitary protection products; the bags made of this kind of cloth are called laminating non-woven bags.
