What is Non Woven Bag?
1.What is non-woven fabric?
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 gift for enterprises and institutions.
2.The differences between polypropylene and polyethylene:
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.
