Plastic is not unfamiliar to every one of us, because it is more common and widely used in all walks of life and in all walks of life. Various kinds of plastic products have greatly enriched everyone's life, but waste plastics are slow to decompose in nature, and it takes more than ten years or even hundreds of years to decompose completely, which has already had a serious impact on people's living environment. Therefore, biodegradable plastics are slowly coming into people's attention and becoming more and more important.

In fact, biodegradable plastics refers to the production process can be appropriate to add a certain amount of additives (such as starch, etc.) so that the degradable plastics of each performance can reach a certain level of regulations to ensure that the performance of the shelf life of the performance is unchanged, and in the use of biodegradable plastics after the decomposition of the material in certain conditions are not harmful to people and the environment.

In addition, there are many kinds of biodegradable plastics, generally divided into: photolytic plastics is to add photosensitizers to plastics, slowly decompose plastics under sunlight; biodegradable plastics are plastics that can be completely decomposed into low molecular compounds under the action of microorganisms. It is characterized by storage and transportation is relatively convenient, only keep dry on the line, the scope of application is also very wide, not only can be used as agricultural film, bags, and widely used in the biopharmaceutical industry; photo-degradable plastics is a combination of photo-degradable and microbial plastic, both photo-degradable and microbial degradation of plastics characteristics. There are also water-degradable plastics, which are plastics with water-absorbent materials that can be dissolved in water after use. Most of them can be used as medical and hygienic products so that they can be easily cleaned and sterilized.

In addition, biodegradable plastics have certain development trends. It can be further studied according to different uses and environmental conditions, and the formula can be improved through molecular design research. Let the performance of biodegradable plastics be more perfect, so that more industries and people can accept biodegradable plastics more quickly.
