Basic Introduction:
 
The "plastic restriction order" implemented since June 1, 2008 clearly stipulates that shopping malls, supermarkets and bazaars are not allowed to provide free plastic shopping bags, and the use of plastic shopping bags less than 0.025mm thick is prohibited. After the implementation of the "plastic restriction order", it has achieved certain results and promoted the development of environmental protection plastic bag industry to a certain extent.
 
Environmentally friendly plastic bags refer:
 
I. Plastic bags conforming to the national standard GB/T21661-2008 are called environmental protection plastic bags, which include recycled plastic bags and new plastic bags. In the process of producing plastic bags, the plastic bags with degradable Masterbatch are called degradable plastic bags, which can be automatically decomposed under certain conditions after 90 days. Bags made of plastic film are collectively referred to as plastic bags. The commonly used plastic bags are: convenience bags, supermarket bags, handbags, flat pockets, plastic bags, horse clips and industrial bags.
 
2. A plastic bag that can melt quickly after being exposed to sunlight and moisture. After testing by the National Environmental Protection product quality supervision and inspection center, all indexes of the products meet or exceed the national quality standards, and are characterized by hygiene, non-toxicity, no pollution, etc. It is one of the most advanced environmental protection products in China. This degradable plastic bag is produced by using non-toxic polyolefin resin and adding degradation agents and other raw materials. Its advent brings hope to reduce or eliminate white pollution.
 
3. Plastic bags that can be recycled again after use.
 
Origin of plastic bags:
 
Plastic bags were first invented by a European factory owner in 1902. Because of its convenience and low price, it is almost everywhere. Since the birth of the plastic bag, it has been destined to be a "disposable" consumable.
 
Composition:
 
Generally speaking, there is no completely environmentally friendly plastic bag, only some plastic bags can be easily degraded after adding some ingredients. That is degradable plastic. In the production process of plastic packaging products, a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizer, biodegradable agent, etc.) are added to reduce the stability of plastic packaging products and are easier to degrade in the natural environment. There are 19 units in Beijing that develop or produce degradable plastics. Tests show that most degradable plastics begin to become thinner, weightlessness, strength decline and gradually split into fragments after being exposed in general environment for 3 months. If these fragments are buried in garbage or soil, the degradation effect is not obvious. There are four shortcomings in using degradable plastics: one is to consume more food; The other is that using degradable plastic products still can't completely eliminate "visual pollution"; The third is that due to technical reasons, using degradable plastic products can't completely solve the "potential harm" to the environment; The fourth is that degradable plastics are difficult to be recycled because they contain special additives.
 
In fact, the most environmentally friendly thing is to use it without plastic bags or with fixed plastic bags to reduce the consumption. At the same time, it can be recycled by the government to reduce environmental pollution.
 
Decomposition time:
 
The current environment-friendly decomposition is relatively faster, and may be decomposed within one year. There are also faster ones. Olympic environmental-friendly plastic bags can be decomposed 72 days after being abandoned.
