Degraded by microorganisms

这种塑料袋是用一种可以被微生物分解的物质做成的。例如用玉米淀粉做成的塑料袋，在细菌、真菌等微生物的作用下进行，能够实现塑料袋的分解功能，而且本身使用的原材料也来源于大自然，不会对环境造成污染。

This plastic bag is made of a material that can be decomposed by microorganisms. For example, plastic bags made of corn starch can be decomposed under the action of bacteria, fungi and other microorganisms, and the raw materials used are also from nature, which will not pollute the environment.

通过光学反应来降解

Degradation by optical reaction

这种塑料袋是通过在塑料中添加一些可以吸收紫外线光的物质，在自然界光照的条件下，不断地碎片化、风化，然后降解成很小的分子，从而实现降解功能。这种类型的塑料袋降解有一定局限性，如果被埋在土里，接触不到阳光就不能被降解。

This kind of plastic bag is used to realize the degradation function by adding some substances that can absorb ultraviolet light into the plastic, and constantly fragmenting and weathering under the conditions of natural light, and then degrading into very small molecules. This type of plastic bag degradation has certain limitations. If it is buried in the soil, it cannot be degraded without exposure to sunlight.

通过生物和光学反应共同作用来降解

Degradation through the joint action of biological and optical reactions

这种塑料袋在光学反应和生物降解的机理共同作用下，能够适应不同的环境，从而大大增加塑料袋降解的进程。这种产品的制备难度较大，成本也比较高，目前还没有大批量的上市。

This kind of plastic bag can adapt to different environments under the joint action of optical reaction and biodegradation mechanism, thus greatly increasing the process of plastic bag degradation. The preparation of this product is difficult and the cost is relatively high. At present, it has not been launched in large quantities.

总之，随着科技的发展，相信未来会有更多采用材料产品的出现。现在不光是塑料袋已经用可降解材料来制作，还有一些购物袋、手提袋、包装袋等都开始用材料制作。人们在享受便利的同时，也避免了使用后的塑料袋变成白色污染，给地球环境带来沉重负担。企业和个人都要响应号召，使用塑料袋产品，?；せ肪?，给子孙后代留下一片绿水青山。

In short, with the development of science and technology, we believe that there will be more products using environmentally friendly materials in the future. Now not only plastic bags have been made of environmentally friendly biodegradable materials, but also some shopping bags, handbags, packaging bags, etc. have begun to be made of environmentally friendly materials. While people enjoy convenience, they also avoid the white pollution of plastic bags after use, which brings a heavy burden to the earth's environment. Enterprises and individuals should respond to the call of the state to use environmentally friendly plastic bags to protect the environment and leave a green landscape for future generations.
