Non-woven bag principle
The non-woven fabric is a non-woven fabric which directly utilizes high-polymer slicing, short fibers or filaments to form a novel fibrous product having a soft, permeable and planar structure by various web forming methods and consolidation techniques. The advantages of non-woven bags compared to traditional plastic bags: non-woven bags are inexpensive, environmentally friendly, practical, widely used, and have prominent advertising positions. Applicable to all kinds of business activities and exhibitions and fairs, is an ideal advertising and promotional gifts for enterprises and institutions.
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, the chemical structure is quite different. The chemical molecular structure of polyethylene has considerable stability and is extremely difficult to degrade. Therefore, it takes 300 years for the plastic bag to be decomposed. The chemical structure of polypropylene is not strong, and the molecular chain can be easily broken, so that it can be effectively degraded. And in the non-toxic form into the next environmental cycle, a non-woven bag can be completely decomposed within 90 days.
Non-woven fabrics are products that do not require a weaving process and are made of cloth-like fabrics, also called non-woven fabrics. Because it only needs to orient or randomly woven the short fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. Most of the non-woven bags are made of spunbonded nonwoven fabric.
To put it simply: non-woven fabrics are not woven and braided together by one yarn, but the fibers are bonded directly by physical means, so when you get the sticky name in your clothes When you find out, you can't draw a single thread. Nonwoven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production speed, high output, low cost, wide application and many raw materials.
Laminating non-woven bag, the product adopts casting method, firm and firm, non-adhesive in the compounding process, soft to the touch, no plastic feeling, no skin irritation, suitable for disposable medical single sheets, bed sheets, surgical gowns, Isolation clothing, protective clothing, shoe covers, and other sanitary protective equipment; such cloth bags are called laminated non-woven bags
