Can vacuum packaging prolong the shelf life of food?
biodegradable packaging bags, it means that they can be degraded. But biodegradable packaging bags are divided into “biodegradable” and “total degradation”. biodegradable packaging pouches refers to add a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizer, biodegradation agent and etc.) in the production to reduce its stability. Then it is easier to be biodegradable in the natural environment.
Fully biodegradable packaging bags mean that all plastic packaging bags are degraded into water and carbon dioxide. The main materials of this fully biodegradable material is processed from corn, cassava and etc into lactic acid, which is called PLA.
At present, the main bio-based material of fully biodegradable packaging bags is composed of PLA and PBAT, which can be completely decomposed into water and carbon dioxide within 3-6 months under the condition of composting (60-70 degrees), without pollution to the environment. Polylactic acid (PLA) is a new type of biological substrate and renewable biodegradable material. The starch raw material is saccharified to obtain glucose, then fermented by glucose and certain strains to produce high-purity lactic acid, synthesized by chemical synthesis. Polylactic acid of molecular weight. It has good biodegradability. After used, it can be completely degraded by microorganisms in nature under specific conditions, and eventually generate carbon dioxide and water, which does not pollute the environment. Biodegradable packaging pouch is very beneficial to the environment and is an environmentally friendly material for people.
