Environmental protection plastic bags are all kinds of biodegradable plastic bags for short, with the development of science and technology, all kinds of materials can replace the traditional PE plastic appear, including PLA, PHAs, PBA, PBS and other polymer materials. Can replace the traditional PE plastic bags. Environmental protection plastic bags have been widely used: supermarket shopping bags, even roll fresh bags, plastic film and other large-scale application examples in China. Jilin Province has adopted PLA (polylactic acid) instead of traditional plastic bags, and achieved good results. In Sanya, Hainan province, starch-based biodegradable plastic bags have also been widely used in supermarkets, hotels and other industries.

The ban, which took effect on June 1, 2008, stipulates that shopping malls, supermarkets and markets should not provide free plastic shopping bags and that plastic bags less than 0.025 mm thick are banned. The implementation of "plastic limit order" has achieved certain results, to a certain extent, to promote the development of environmental protection plastic bag industry.

Environmental protection plastic bags refer to:

First, in line with the national standard GB/T21661-2008 plastic bags are called environmental protection plastic bags, environmental protection plastic bags include recycled plastic bags and new plastic bags. In the process of producing plastic bags, the plastic bags with degradation master materials are called degradable plastic bags. After 90 days of degradation, the plastic bags can be decomposed automatically under certain conditions. Plastic film as raw materials for the production of bags collectively referred to as plastic bags, we commonly used plastic bags are: convenient bags, supermarket bags, handbags, flat bags, plastic bags, horse entrain and industrial packaging bags.Set quality standards, with health, non-toxic, pollution-free characteristics, is one of the most advanced environmental protection products in China. This kind of degradable plastic bag is made of non-toxic polyolefin resin and adding degradating agent. Its appearance has brought hope for reducing or eliminating white pollution.

Plastic bags that can be recycled twice after use.

Components of plastic bags:

Generally speaking, there is no completely environmental protection of plastic bags, only some plastic bags after adding some ingredients, easy to degrade some. Biodegradable plastics. In the production process of plastic packaging products adding a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizer, biodegradant, etc.), the stability of plastic packaging products decreased, easier to degrade in the natural environment. Beijing area has 19 research and development or production of degradable plastics units. Tests show that most degradable plastics begin to thin, lose weight, lose strength and gradually break into pieces after 3 months of exposure in general environment. If the debris is buried in garbage or soil, the degradation effect is not obvious. The use of degradable plastic has four shortcomings: one is to consume more food; Second, the use of degradable plastic products can not completely eliminate "visual pollution"; Third, due to technical reasons, the use of degradable plastic products can not completely solve the "potential harm" to the environment; Fourthly, degradable plastics are difficult to recycle because of special additives.

In fact, the most environmentally friendly, is not plastic bags or fixed plastic bag use, reduce the amount of consumption, and can be recycled by the government, can reduce environmental pollution.
