　　Plastic bags can be seen everywhere, bringing convenience to our daily lives. It can be seen that our lives are inseparable from plastic bags, but environmental pollution caused by large -scale use cannot be ignored. Today, people are more and more concerned about pollution caused by plastic bags. Plastic bags are also developing towards environmental protection routes. At present, the development trend of newly developed plastic packaging membranes at home and abroad is to develop towards high efficiency, non -toxic, harmless, green and environmentally friendly, good quality, cheap, and easy to use.

　　Biodegradable packaging bags came into being, and biodegradable packaging bags did not cause environmental pollution. The degradable packaging bag not only achieves convenience, but also protects the environment. At present, degradable packaging bags have not yet been popularized, so we must not understand the degradable packaging bags. Below Qingdao Zhou's plastic will explain in detail for you!

　　The meaning of degradable packaging bags is that they can be degraded, but can be divided into "degradable" and "total degradable". The degradable packaging bag refers to the addition of a certain amount of additives (such as starch, degeneration starch or other cellulose, photoretinomers, biodegradable agents, etc.) in the natural environment in the production process in the natural environment. In the decline in stability. The fully degradable packaging bag refers to the degradation of plastic packaging bags to water and carbon dioxide. The main source of this completely degradable material is corn, cassava and other products processed into lactic acid, namely PLA.

　　Polymine (PLA) is a new type of nano -organism and renewable biodegradable material. The starch is converted into glucose by glycating, and then transformed into high -purity lactic acid through the fermentation of glucose and certain strains. It has good biodegradation, and can be completely degraded by natural microorganisms under certain conditions after use. Carbon dioxide and water will not pollute the environment, which is very beneficial to protecting the environment. It is an environmentally friendly material for workers.
