Main bio based materials for degradable packaging bags

　　Plastic bags can be seen everywhere, bringing convenience to our daily life. It can be seen that we cannot live without plastic bags, but the environmental pollution caused by large-scale use cannot be ignored. Nowadays, people pay more and more attention to the pollution caused by plastic bags. Plastic bags are also moving towards environmental protection. At present, the development trend of newly developed plastic packaging film at home and abroad is towards the direction of high efficiency, non-toxic, harmless, green, environmental protection, good quality, cheap price and easy use.

　　Biodegradable packaging bags emerge as the times require. Biodegradable packaging bags will not cause environmental pollution. The degradable packaging bag not only realizes the convenience, but also protects the environment. At present, degradable packaging bags have not been popularized, so we can not help understanding degradable packaging bags. The manufacturer of environment-friendly plastic bags will give you a detailed explanation!!

　　The meaning of degradable packaging bags is that they can be degraded, but degradable bags can be divided into "degradable" and "total degradable". Degradable packaging bags refer to plastic packaging bags that are easy to degrade in the natural environment after adding a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizer, biodegradable agent, etc.) during the production process. In the decline of stability. Fully degradable packaging bags refer to the plastic packaging bags degraded into water and carbon dioxide. The main sources of this fully biodegradable material are corn, cassava and other products processed into lactic acid, namely PLA.

　　Polylactic acid (PLA) is a new nano biological and renewable biodegradable material. Starch is converted into glucose through saccharification, and then into high-purity lactic acid through glucose and fermentation of some strains. It has good biodegradability and can be completely degraded by natural microorganisms under specific conditions after use. Carbon dioxide and water will not pollute the environment. They are very useful for protecting the environment. They are environmentally friendly materials for workers.
