Limited to the name of the real name of all kinds of shopping bags large PK

In accordance with the notice issued by the General Office of the State Council on the use of plastic shopping bags for the restriction of production and sales, since June 1, 2008, all the supermarkets, shopping malls and bazaars have been used for the sale of plastic shopping bags. No plastic shopping bags are available free of charge. It is reported that this provision has been difficult to strictly implement. In many supermarkets, each year only to sell plastic bags will be able to earn tens of millions of dollars, "plastic limit order" or even become "selling plastic order", "plastic limit order" in name only. Xiao Bian today to the current market on the various types of shopping bags for analysis and comparison, who is more environmentally friendly, consumers will be at a glance.

Currently on the market available shopping tools are: plastic shopping bags, non-woven shopping bags, paper shopping bags, cotton and linen shopping bags and shopping baskets.

Plastic shopping bags

What is a plastic shopping bag?

Plastic shopping bags

Plastic shopping bags are polyolefin as the main raw material, the appropriate addition of other materials made of packaging materials. The main products include low density polyethylene or high pressure polyethylene (LDPE), high density polyethylene or low pressure polyethylene (HDPE), linear low density polyethylene (PEPE), high density polyethylene (LLDPE) and metallocene polyethylene (mLLDPE) four categories. In order to reduce its cost, in recent years, most companies have joined about 30% of calcium carbonate filled with plastic shopping bags, such plastic shopping bags in the garbage dump when the release of toxic gases. Just introduced the national plastic shopping bag 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 now is whether the problem can be recovered.

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. Starch-based plastic shopping bags with starch as the main raw material, and starch from food, because of the current soaring food prices, countries have banned the consumption of food to carry out industrialization projects, so the prospect of such products is not good.

Degradable plastic shopping bags - these shopping bags to fully degradable plastic as raw materials, with complete degradation performance. Product abandoned in the wild can be completely degraded into small molecules of microorganisms, without any environmental pollution, the current 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 (APC) degradation of plastic, which is currently shouting the industrial by-product of carbon dioxide as raw material, neither consumption of food, but also reduce the emissions of carbides , To eliminate the greenhouse gas effect caused by the "El Niño" phenomenon, serve two purposes, so the market prospects.

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