New environmentally friendly plastic bags - types of degradable plastics - what are the new degradable plastics? In order to contribute to the cause of environmental protection and avoid being fined by relevant departments, it is inevitable for enterprises to use degradable plastics. However, there are more than one type of degradable plastics. There are many types. If enterprises do not know how to distinguish, they may buy the wrong type. Here is a brief introduction to the types of degradable plastics - what are the new degradable plastics?
1. Photodegradable plastics
This is the earliest degradable plastic, which is relatively cheap, but photodegradable plastic has high requirements for sunshine. If it encounters cloudy and rainy weather or bad climate, it will lose its effect. With the continuous development of science and technology, photodegradable plastics are gradually eliminated by the market.
2. Biodegradable plastics
Biodegradable plastics are a kind of degradable plastics with high utilization rate at present. Compared with other types of degradable plastics, biodegradable plastics have the fastest degradation speed. As long as microorganisms are used, the degradation can be easily completed, and the scope of application is also relatively wide, which can be used in almost all walks of life.
3. Photo / biodegradable plastics
This is a degradable plastic combining photodegradation and biodegradation. The degradation efficiency of photodegradable / biodegradable plastics is very good and the degradation speed is relatively fast. However, the disadvantage is that the price is relatively high. If it is not for some special industries and high requirements for degradation speed, it is not recommended to purchase light / biodegradable plastics, which will increase the cost of the enterprise.
4. Water degradable plastics
The application range of water degradable plastics is relatively narrow. Most of them are used in the production of medical gloves. They can be degraded as long as they encounter water. If it is in other industries, the use of water degradable plastics will be greatly limited. Therefore, although the effect of water degradable plastics is better, it may not be applicable if it is not in the pharmaceutical industry.
There are four main types of degradable plastics, namely water degradable plastics, photodegradable plastics, biodegradable plastics and light / biodegradable plastics. Enterprises need to choose according to the needs of their industry, so as to buy degradable plastics suitable for enterprises and avoid wasting money.
