The difference between degradable plastic bags and fully degradable plastic bags, and recommendations for ordering degradable packaging bags

Degradable packaging bags are packaging bags that can be degraded, but degradable packaging bags are divided into two types: "biodegradable plastic bags" and "fully biodegradable plastic bags".

Biodegradable plastic bags refer to plastic packaging bags that have reduced stability due to the addition of a certain amount of additives (such as starch, modified starch, or other cellulose, photosensitizers, biodegradants, etc.) during production, and are therefore easier to degrade in the natural environment.

Fully biodegradable plastic bags refer to plastic packaging bags that completely degrade into water, carbon dioxide, and other small molecules. The main source of this fully biodegradable material is polylactic acid, or PLA, which is 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 certain strains to produce high-purity lactic acid, which is then chemically synthesized into polylactic acid with a certain molecular weight. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use, eventually producing carbon dioxide and water without polluting the environment. This is a recognized environmentally friendly material, which is very beneficial for environmental protection.

Currently, the main bio-based materials for fully biodegradable plastic bags consist of PLA+PBAT, which can be completely decomposed into water and carbon dioxide under composting conditions (60-70 degrees) in 3-6 months without polluting the environment.

Why add PBAT? PBAT is a copolymer of adipic acid, 1,4-butanediol, and terephthalic acid. It is a fully biodegradable chemically synthesized aliphatic-aromatic polymer. PBAT has excellent flexibility and can be processed into various shapes through film extrusion, blowing, extrusion coating, etc. The purpose of blending PLA and PBAT is to improve the toughness, biodegradability, and processing performance of PLA.
