The Four Major Advantages Of Non-Woven Bags

Non-woven bags represent a new alternative to "white pollution" (plastic waste). With the rise of new energy sources and increasing environmental pollution, relevant authorities have begun to advocate for environmental protection and energy conservation. In an effort to eliminate this "white pollution" and improve our quality of life, many environmentally conscious individuals have turned to a new product: the non-woven bag. Its advantages are widely recognized. Non-woven shopping bags are actually made from plastic-based, non-textile fabrics; many people mistakenly assume that because they are called "bags," they must be made of natural materials-a common misconception. Stitch-bonded non-woven bags are a type of dry-laid non-woven fabric; the stitch-bonding method utilizes warp-knitting loop structures to reinforce fiber webs, yarn layers, non-textile materials (such as plastic films or metal foils), or combinations thereof, thereby creating a non-woven fabric. The most common raw materials for non-woven bags are polypropylene (abbreviated as PP) or polyethylene terephthalate (abbreviated as PET, commonly known as polyester). In terms of environmental impact, they are similar to ordinary plastic shopping bags in that neither is fully biodegradable. From a specific cost-performance perspective, under identical conditions, non-woven bags generally possess lower tensile strength than plastic bags and are not waterproof; furthermore, their price is often several times higher than that of plastic bags. Needle-punched non-woven bags are another type of dry-laid non-woven fabric; this method utilizes the piercing action of barbed needles to mechanically reinforce a loose fiber web, consolidating it into a cohesive fabric. Notably, PP-much like the PE used in standard plastic shopping bags-belongs to the category of the "Five Major General-Purpose Plastics"; these are plastic varieties that do not degrade even after 50 years. The production cost of non-woven bags primarily comprises two components: the cost of raw materials and the cost of processing the bags. A wide variety of non-woven fabrics with differing specifications and cost structures are available on the market. Spunlace non-woven bags are produced by directing high-pressure, fine jets of water onto one or more layers of fiber webs; this causes the fibers to entangle with one another, thereby reinforcing the web and imparting a certain degree of tensile strength. Thermal-bonded non-woven bags are created by incorporating fibrous or powdered thermoplastic bonding agents into a fiber web; the web is then subjected to heating, melting, and subsequent cooling to consolidate it into a finished fabric. Non-woven bags are eco-friendly products and a widely used type of packaging bag, primarily utilized for shopping, packaging, advertising, electronics, apparel, and decorative items. The most distinctive feature of non-woven fabric is its eco-friendly properties-qualities that plastic products lack; specifically, the time required for it to undergo natural degradation is significantly shorter than that of plastic bags. Consequently, non-woven bags are widely recognized as the most economical and practical choice for eco-friendly shopping bags.
