Plastic shopping bags

Plastic shopping bag is made of polyolefin as the main raw material, the appropriate addition of other materials made of packaging materials. The polyolefin is mainly polyethylene (PE), commonly known as soft, the main products include low density polyethylene or polyethylene (LDPE), high density polyethylene or polyethylene (HDPE) and linear low density polyethylene (LLDPE) and metallocene polyethylene (mLLDPE) four categories. In order to reduce the cost, most companies are adding about 30% calcium carbonate filled plastic shopping bags, plastic shopping bags such as garbage incineration in the field does not emit toxic gases. The newly introduced national plastic shopping bags standards will be divided into three categories of plastic shopping bags:

Ordinary plastic shopping bags - the use of polyolefins and fillers as raw materials, such plastic shopping bags are not biodegradable, abandoned in the field will not degrade. This kind of plastic shopping bag has excellent recyclability, and can be recycled for many times. The performance of the recycled material is slightly reduced in different degrees, but can be used for shopping bags or garbage bags with low production requirements and strict color requirements. The key question is whether the problem can be recovered.

Starch based plastic shopping bags - this kind of shopping bag with modified starch as the main raw material, appropriate to add a small amount of other degradable materials to improve its performance. The plastic shopping bags can be degraded naturally in the field after use.

Degradable plastic shopping bags - this kind of shopping bags can be completely degradable plastics as raw material production, with complete degradation performance. Products abandoned in the field can be completely degraded into small molecular micro-organisms, without any environmental pollution, foreign countries to promote such plastic shopping bags. Can be divided into the following three categories in accordance with the specific composition of degradable plastics:

(1) PLA and PHA biodegradable plastics, which are synthesized from natural starch as raw material, need to consume a large amount of food, so the development space is limited.

(2) using carbon dioxide as raw materials for the synthesis of aliphatic polycarbonate (APC) degradable plastic, it is the people cry of industrial by-product carbon dioxide as raw material, not only do not consume food, but also can reduce the emissions of carbide, eliminate the phenomenon of global warming, greenhouse gases caused by shooting two birds with one stone and thus have broad market prospects.

(3) the complete degradation products of non starch degrading agent are added in the common plastics, which are in the stage of industrialization.
