Do You Really Know The Soft Loop Handle Bags?

   Plastic shopping bags are polyolefin as the main raw material, the appropriate addition of other materials made of packaging materials. Polyolefin used mainly polyethylene, commonly known as soft, the main products include low-density polyethylene or high-pressure polyethylene, high-density polyethylene or low-pressure polyethylene, linear low-density polyethylene and metallocene polyethylene four categories. In order to reduce its costs, most companies have joined about 30% of calcium carbonate filled with plastic shopping bags, such plastic shopping bags due to incineration in the garbage dump when the release of toxic gases.Soft Loop Handle Bags

    Just introduced the national plastic shopping bags standard plastic shopping bags are divided into the following three categories: ordinary plastic shopping bags - the use of polyolefins and fillers as raw materials, such plastic shopping bags do not have degradation performance, abandoned in the wild will not be degraded.

    Such plastic shopping bags have excellent recyclability, can be recycled several times. The performance of the recovered material is slightly reduced in varying degrees, but it can be used in shopping bags or garbage bags where the performance requirements are not high and the color requirements are not strict. The key question is whether the problem can be recovered.Soft Loop Handle Bags

    Starch-based plastic shopping bags - these shopping bags with modified starch as the main raw material, the appropriate addition of a small amount of other biodegradable materials to improve its performance. The plastic shopping bags are discarded in use after the field can be naturally degraded. Degradable plastic shopping bags - these shopping bags to fully degradable plastic as raw materials, with complete degradation performance.

    Product abandonment in the wild can be completely degraded into small molecules of microorganisms, without any environmental pollution, foreign to promote such plastic shopping bags. In accordance with the specific composition of completely degradable plastics can be divided into the following three categories:

   (1) PLA, PHA biodegradable plastics synthesized by bio-fermentation with natural starch as raw materials require considerable consumption of food, so the development space is limited.

   (2) carbon dioxide as raw material synthesis of aliphatic polycarbonate degradation of plastic, which is shouting by the industrial by-product of carbon dioxide as raw material, neither the consumption of food, but also reduce the emissions of carbides, the elimination of greenhouse gases Resulting in global warming phenomenon, do both, and thus the market prospect is broad.Soft Loop Handle Bags

   (3) in the ordinary plastic to add non-starch degradation agent of the complete degradation of products, in the industrialization stage, such as the degradation of reliable performance, very promising.Soft Loop Handle Bags
