Non-woven bags and plastic bags are the same plastic products, it is not environmentally friendly? As more and more citizens choose to use non-woven bags as substitutes for plastic bags, some people have put forward such a view. This reporter has learned that the main component of non-woven bags of polypropylene or polyester, these polymers do not really can be degraded in a short time. However, some experts said that whether biodegradable is not the only measure of environmental protection bags. The non-woven reusable features still determine that it is environmentally friendly. "The plastic bag and the non-woven bag are made of plastic material made of high polymer, so the material properties are the same." Dong Zhaohong, Associate Professor of Chemistry and Environment College of Qingdao University told reporters. She said that polypropylene, polyester and other polymers extracted from the oil, the degradation takes as little as a few months, as long as several decades. Therefore, she said: "From a non-degradable point of view, non-woven bags are not environmentally friendly." China Plastics Processing Association Plastics Recycling Committee, vice president Dong Jin-lion told reporters that for tenacity and durability considerations, and now Non-woven bags on the market mostly do not add photodegradable agent. However, he said: "Non-woven bags can be reused, so they are still environmentally friendly." "The definition of eco-bags is not necessarily biodegradable, but can also be considered from the point of view of reuse." Dong, In thickness, non-woven fabric is several times the plastic bag; in the manufacturing process, the plastic bag is used in the blow molding process, and non-woven fabric is used in the spray process. These make non-woven bags than plastic bags sturdy. At the same time, non-woven polyester components make it easy to clean, more conducive to re-use.
