PLA degradable packaging bags, environmentally friendly plastic bags, clothing bags

   Plastic packaging bags are everywhere, plastic packaging bags bring convenience to our daily lives when in use, it is clear that our lives cannot do without plastic bags, but is the environmental impact caused by large-scale use pollution cannot be ignored. Nowadays, the pollution problems caused by plastic bags are receiving increasing attention, plastic packaging bags also are continuously developing towards an environmentally friendly direction, the current trend in newly developed plastic packaging films both domestically and internationally is towards high performance, non-toxic and harmless, green and environmentally friendly, good quality and low price, and convenient to use. Degradable packaging bags emerged, degradable packaging bags will not cause environmental pollution. Degradable packaging bags achieve both convenience, and environmental protection. Currently, degradable packaging bags are not yet widespread, and it is likely that many people do not know much about them. Below, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will provide an explanation.

   Degradable packaging bags, implicitly meaning they can be degraded, but degradable packaging bags are divided into 'degradable' and 'fully degradable' types. Degradable packaging bags refer to plastic packaging bags that have a certain amount of additives (such as starch, modified starch or other cellulose, photosensitizers, biodegradants, etc.) added during production to reduce their stability, making them relatively easier to degrade in the natural environment. Fully degradable packaging bags refer to plastic packaging bags that completely degrade into water and carbon dioxide. The main source of this fully degradable material is lactic acid, also known as PLA, processed from corn, cassava, etc.

  Polylactic acid ( PLA) is a new type of bio-based and renewable biodegradable material. Starch raw materials are saccharified to obtain glucose, which is then fermented with specific strains to produce high-purity lactic acid, and then polylactic acid of a certain molecular weight is synthesized through chemical synthesis methods. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use, ultimately producing carbon dioxide and water, without polluting the environment. This is very beneficial for environmental protection and is an environmentally friendly material for workers.

   Currently, the main bio-based material for fully degradable packaging bags is composed of PLA+PBAT. Under composting conditions (60-70 degrees Celsius), it can completely decompose into water and carbon dioxide within 3-6 months, without environmental pollution. Why add PBAT? The professional flexible packaging manufacturer explains that PBAT is a copolymer of adipic acid, 1,4-butanediol, and terephthalic acid. It is a chemically synthesized aliphatic-aromatic polyester that is fully biodegradable. PBAT has excellent flexibility and can be processed by film extrusion, blown film processing, extrusion coating, and other molding processes. The purpose of blending PLA and PBAT is to improve PLA's toughness, biodegradability, and molding performance. PLA and PBAT are incompatible, so choosing a suitable compatibilizer can significantly improve PLA's performance.
