Degradable packaging bags, the implication is that they can be degraded, but degradable packaging bags are divided into "degradable" and "total degradation". Degradable packaging bag refers to the addition of a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizer, biodegradation agent, etc.) in the production process to reduce its stability, and then it is easier to be in the natural environment Degradable plastic packaging bag. Fully degradable packaging bags mean that all plastic packaging bags are degraded into water and carbon dioxide. The main source of this fully degradable material is processed from corn, cassava, etc. into lactic acid, which is PLA.
Polylactic acid (PLA) is a new type of biological substrate and renewable biodegradable material. The starch raw material is saccharified to obtain glucose, which is then fermented by glucose and certain strains to produce high-purity lactic acid, and then synthesized by chemical synthesis. Polylactic acid of molecular weight. It has good biodegradability. After use, 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. This is very beneficial to the environment and is an environmentally friendly material for workers.
At present, the main bio-based material of fully degradable packaging bags is composed of PLA+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. Why do you need to add PBAT? Professional flexible packaging manufacturers tell and explain that PBAT is a copolymer of adipic acid, 1,4-butanediol and terephthalic acid. It is a chemically synthetic fat that can be too fully biodegradable Group-aromatic polymer, PBAT has excellent flexibility, and can be used for film extrusion, blowing processing, extrusion coating and other molding processes. The purpose of blending PLA and PBAT is to improve the toughness, biodegradation, and molding performance of PLA. PLA and PBAT are not compatible, so choosing a suitable compatibilizer can significantly improve the performance of PLA.
We offer patented full biodegradable film and PVA bag, all products are made by casting equipment, It is different from traditional blow molding products, all blow molding products are non full biodegradable. We can produce pva films and bags in full transparent and various colors. and the PVA film is more smooth than the traditional blow molding products.
we also offer organic material full biodegradable film and bags with patented raw material and production Process.
