Biodegradable PLA stics refer to PLA stics that are degraded by the action of naturally occurring microorganisms such as bacteria, molds (fungi) and algae.The ideal biodegradable PLA stic is a polymer material that has excellent performance, can be completely decomposed by environmental microorganisms after being discarded, and is inorganicized to become an integral part of the carbon cycle in nature. “Paper”is a typical biodegradable material, and”synthetic PLA stic”It is a typical polymer material. Therefore, biodegradable PLA stics are both”Paper”and”synthetic PLA stic”These two materials are polymeric materials in nature.Completely biodegradable PLA stics are mainly made from natural polymers (such as starch, cellulose, chitin) or agricultural by-products through microbial fermentation or synthesis of biodegradable polymers, such as thermo PLA stic starch PLA stics, aliphatic polyesters, polylactic acid ,starch/Polyvinyl alcohol and the like belong to this type of PLA stic.Biodegradable PLA stics based on natural substances such as starch currently mainly include the following products: polylactic acid( PLA ), polyhydroxyalkanoate(PHA), starch PLA stics, bioengineering PLA stics, bio-general-purpose PLA stics, etc. The biodegradable bag made of polylactic acid is degradable, has good performance and high reuse rate, and can be decomposed into carbon dioxide and water under composting conditions after being discarded.
