Non-woven bag manufacturers talk about the principle of making non-woven bags

Non-woven bag manufacturer, non-woven bag is a kind of non-woven fabric, which directly uses high-polymer slicing, short fiber or filament to form soft, breathable and flat through various web forming methods and consolidation techniques. Structure of new fiber products. 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, it 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 cloth, also called non-woven fabric. 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.

Non-woven bag manufacturer analysis, laminating non-woven bag, the product adopts casting method, compound and firm, no glue in the compounding process, soft touch, no plastic feeling, no skin irritation, suitable for disposable medical use Single, bed sheets, surgical gowns, isolation suits, protective clothing,
