Environmental bags should have two aspects.
Environmental bags should have two aspects. On the one hand, they are made of natural materials and can be reused; small compared to other materials). However, ordinary plastic bags are difficult to degrade after being discarded in the environment, and even a small part of them will produce harmful substances.
Definition:
Plastic shopping bags are consumables in daily life, and China consumes a lot of plastic shopping bags every year. While providing convenience for consumers, plastic shopping bags also cause serious waste of energy 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 at will, becoming the main source of "white pollution". More and more countries and regions have restricted the production, sale and use of plastic shopping bags. In order to implement the scientific concept of development and build a resource-saving and environment-friendly society, effective measures should be taken from the source to urge enterprises to produce durable and easy-to-recycle plastic shopping bags, guide and encourage the masses to use plastic shopping bags rationally, and promote the comprehensive utilization of resources. Protect the ecological environment and further promote energy conservation and emission reduction.
The so-called environmentally friendly bags generally refer to bags that can be made of materials that can be naturally degraded, and the time to be decomposed [1] will not be too long. At the same time, they can also be reused many times.
type
In this society full of environmental protection topics, reusable bags have become a daily necessity for people. But how much do we know about reusable bags? Let's take a look at the small encyclopedia of environmental protection bags.
The so-called "environmentally friendly cloth bags" that everyone uses are roughly divided into the following categories:
1. Non-woven bags (can be called environmental protection only after repeated use and final recycling)
2. Canvas bag (compared to other materials, it is the most environmentally friendly and does not pollute the environment)
3. Cotton bags (same characteristics as canvas bags)
4. Flannel bags (mostly rayon-cotton polyester, just like the fabrics on our clothes, needless to say)
5. Polyester cloth vest bag (polyester cloth, similar to the cloth of our common umbrella, and the lining used for clothing, because the environmental protection bag made of this kind of cloth is usually vest type, so it is called a vest bag)
6. Other environmentally friendly fabric bags (hemp fabric and canvas surface have different properties)
Material
Environmental protection bags are either pure cotton or non-woven, and environmental protection depends on whether these materials can degrade. Among them, the national standard environmentally friendly processing material is polyethylene, because its degradation ability is better than other materials.
shape
There are various styles of environmental protection bags to meet different needs.

Classification by shape: three-dimensional environmental protection bag, flat environmental protection bag (common environmental protection bag without thickness), bottom organ environmental protection bag (that is, the environmental protection bag with thickness at the bottom and no thickness on the surface), non-woven environmental protection bag with composite (covered) film , vest environmental protection bag, folding bag (purse bag), rope environmental protection bag, hand rope environmental protection bag
Classification by pattern: pure color (plain color) environmental protection bags, color environmental protection bags, heat transfer environmental protection bags, offset environmental protection bags, embroidered environmental protection bags, silk-screened environmental protection bags (the most common environmental protection bags with printed colors)
Sorted by size: standard-size reusable bags, mini reusable bags, extra-large reusable bags,
Classification according to special requirements: customized environmental protection bags, thermal insulation environmental protection bags, silver-faced environmental protection bags, and environmental protection shopping bags.
According to different age levels, environmental protection bags can be divided into the following categories: cartoon-type environmental protection bags are suitable for some children, simple-type environmental protection bags are suitable for friends who like simplicity, and DIY environmental protection bags are suitable for some friends who like to design. The eco-friendly bags are suitable for some companies to sell together with their products to achieve the benefits of publicity.
