Development and Application of Environmentally Friendly Plastic Bags

There should be two aspects to eco-friendly bags. On the one hand, they are made of natural materials that can be reused; On the other hand, if it breaks down, it will not leave solid waste in the natural environment, causing harm to the environment (or the harm to the environment is relatively small compared to other materials). However, general plastic bags are difficult to degrade after being discarded in the environment, and even a small portion of them can produce harmful substances after decomposition.

Plastic shopping bags are consumables in daily life, and China consumes a large amount of plastic shopping bags every year. Plastic shopping bags not only provide convenience for consumers, but also cause serious waste of energy resources and environmental pollution due to excessive use and inadequate recycling. Especially ultra-thin plastic shopping bags are prone to damage and are mostly discarded randomly, becoming the main source of "white pollution". Currently, more and more countries and regions have restricted the production, sales, and use of plastic shopping bags. To implement the Scientific Outlook on Development, build a resource-saving and environmentally friendly society, effective measures are taken from the source to urge enterprises to produce durable and easily recyclable plastic shopping bags, guide and encourage the rational use of plastic shopping bags by the public, promote comprehensive utilization of resources, protect the ecological environment, and further promote energy conservation and emission reduction work.

The so-called "environmentally friendly cloth bags" that people use now can be roughly divided into the following types:

Non woven fabric bags (can only be considered environmentally friendly after being reused and finally recycled)

Canvas bag (compared to other materials, it is the most environmentally friendly and does not pollute the environment)

Cotton bag (same characteristics as canvas bag)

Velvet bags (mostly made of artificial cotton cotton polyester, just like the fabric on our clothes, needless to say)

Polyester vest bag

Other environmentally friendly fabric bags (hemp fabric and canvas surface have different properties)

Using eco-friendly bags:

Can significantly reduce the use of plastic bags;

Longer service life than paper bags;

Can be recycled;

Low price, easy to promote.

The overall scale of China's environmental protection industry is relatively small, and its boundaries and connotations are still constantly 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 gradually become an industry that improves the quality of economic operation, promotes economic growth, and improves the level of economic technology. The direction of industrial connotation expansion will mainly focus on clean technology, clean products, environmental services, and other aspects. The concept of China's environmental protection industry will also evolve into "environmental industry" or "green industry".
