Environmental bags should have two aspects, on the one hand is made of natural materials can be reused; On the other hand, when broken, solid waste does not remain in the natural environment, causing harm to the environment (or the harm to the environment is relatively small compared to other materials). However, ordinary plastic bags are difficult to degrade after being discarded in the environment, and harmful substances will be produced even after a small part of the decomposition.

Plastic shopping bags are consumable goods in daily life. China consumes a large number of plastic shopping bags every year. Plastic shopping bags not only provide convenience for consumers, but also cause serious waste of energy and resources and environmental pollution due to excessive use and inadequate recycling. In particular, ultra-thin plastic shopping bags are easily damaged and most of them are discarded carelessly, becoming the main source of "white pollution". At present, more and more countries and regions have restricted the production, sale and use of plastic shopping bags. To implement the scientific outlook on development, building a resource-conserving and environment-friendly society, from the source to take forceful measures to urge the enterprise production of durable, easy to recycle plastic shopping bags, guide the rational use of plastic shopping bags, encouraging masses, promote the comprehensive utilization of resources, protect the ecological environment, further promote energy conservation and emissions reduction work.

Now we use the so-called "environmental protection cloth bag" is roughly divided into several kinds:

Non-woven bags (environmentally friendly only when reused and finally recycled)

Canvas bag (compared with other materials, it is the most environmentally friendly, no pollution to the environment)

Cotton bags (same characteristics as canvas bags)

Flannelette bags (mostly rayon-polyester, the same fabric as our clothes needless to say)

Polyester vest bag (polyester fabric, similar to our common umbrella cloth, and clothing lining, because the environmental protection bag made of this fabric is usually vest type, so called vest bag)

Other environment-friendly fabric cloth bags (linen cloth and canvas surface are different in nature)

Use reusable bags:

Can greatly reduce the use of plastic bags;

Longer service life than paper bag;

Can be recycled;

Low price and easy to promote.

The overall scale of China's environmental protection industry is still relatively small, and its boundaries and connotations are still expanding and enriching. With the development of China's social economy and the adjustment of industrial structure, the direct contribution of China's environmental protection industry to the national economy will grow from small to large, and gradually become an industry that improves the quality of economic operation, promotes economic growth, and raises the economic and technological level. The direction of industrial connotation expansion will mainly focus on clean technology, clean products, environmental services and so on. The concept of China's environmental protection industry will also evolve into "environmental industry" or "green industry".
