Classification of degradable plastics

Degradable plastics are a new type of plastic varieties, developed abroad can be degradable plastics began in the 1970s, which was mainly developed photodegradable plastics, aims to solve the plastic waste, especially disposable plastic packaging products, the environmental pollution problems , to the 1980s, research and development shift to biodegradable plastics based, and, while there have been no oil with renewable resources such as plant starch and cellulose, chitin and other animals as raw materials to produce bio-degradable plastics. In addition, the development of a microbial fermentation production of biodegradable plastics. portable sprayers A class of clinical applications can already living degradation of medical plastic, such as polylactic acid also attracted attention, hopes to use it to solve the plastic pollution problem, but, for this type of plastic is still classified as degradable plastics There are different opinions, Japan Degradable Plastics Council opinion that can not be classified degradable plastics. However, a new class of biodegradable plastic is plastic point of view, should also include a living body degradable plastics, and it might be from the use of biodegradable plastics will be classified into the environment (natural) and bio-degradable plastics (Environment) degradable plastics. The latter has been used in the medical surgical sutures, artificial bones.
Chinese basic research and development of degradable plastics with the world. However, the Chinese degradable plastics research and development began agricultural mulch film. China is a large agricultural country, mulch consumption accounts first in the world to solve the accumulated residue mulch on farmland on the harm caused by plant root growth and affect crop yields,trigger sprayer as well as plastic film for agricultural tractor problems hinder the operation of the 1970s that began the development of photodegradable plastic film before and after 1990, there has been filled in the General Plastics starch biodegradable plastics, while the light degradable plastics based on starch filled simultaneously develop both photodegradation and biodegradation feature film . Currently various types of degradable plastic film being developed, the application is still in the demonstration phase. In recent years, as China's living standards improve, disposable plastic packaging products bring increasingly serious environmental pollution problems, therefore, are also being actively developed for packaging, mainly disposable packaging biodegradable plastic products, such as garbage bags, shopping bags, lunch boxes, etc..
