How Do You Choose A Nonwoven Bag?
Jul 19, 2018

With the increase of new energy, relevant departments continue to advocate environmental protection and energy saving, but environmental pollution is still getting worse. To get rid of this white pollution and make the surrounding environment better, many environmentally-friendly people are starting to develop new products, including a new product called nonwoven bag. Nonwoven bags are nonwoven fabrics made of plastic. Many people think that a cloth is natural, but this is a misunderstanding.


The main material of the nonwoven cloth bag is non-woven fabric. Nonwoven fabric is a nonwoven fabric with a direct use of high polymer chips, short fibers or filament through a variety of fiber mesh forming methods and consolidation technology formed with a soft, breathable and flat structure of the new fiber products.


Stitched woven nonwoven fabric is a kind of dry nonwovens. The stitching method is made of warp knitted coil structure, which is used to make non-woven fabrics, such as mesh, yarn layer and non-woven material. Commonly used non-woven raw materials are polypropylene non-woven bags or polyethylene terephthalate, which are environmentally friendly and can not completely degrade like ordinary plastic shopping bags. In terms of specific cost performance, the strength of non-woven fabric bags under the same conditions is not as good as that of plastic bags, and it is not waterproof, and its price is several times higher than that of plastic bags.  Needle punched nonwoven fabric bag: it is a kind of dry non-woven fabric. Needle punched nonwoven fabric is made by using the puncture effect of needles, and the loose net is reinforced into cloth. In particular, PP, like the PE used in plastic shopping bags, belongs to the five major general-purpose plastics. It belongs to a plastic variety that can not be degraded for 50 years.


The production cost of non-woven bags mainly includes two departments, one is the cost of raw materials, and the other is the processing cost of cloth bags. At present, there are many specifications for non-woven fabrics available in the market, and the cost is also different. Spunlaced nonwoven bag: the high pressure water flow is sprayed to one or more layers of fiber network to bind the fiber to each other, so that the fiber network can be strengthened and has a certain strength. Heat bonded nonwoven fabric bag: it refers to adding fibrous or powdered hot melt bonding material into the fiber net, and the mesh is further strengthened by heating, melting and cooling. We classify non-woven bags into products of environmental protection, because the biggest feature is the environmental protection function that plastic products do not have. Its natural degradation time is much lower than that of plastic bags. Therefore, non-woven fabrics made of non-woven fabrics have been recognized as the most economical and environment-friendly shopping bags.
