The commonly used non-woven fabrics are polypropylene (PP, commonly called polypropylene) nonwoven bag or Polyterephthalate (PET, commonly known as polyester), and the environmental protection and ordinary plastic shopping bags can not be completely degraded. From the specific cost performance, the strength of the non textile bag under the same condition is not as strong as plastic bag, and it is not waterproof, and its price is more than a few times more than that of plastic bag. 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.
