The advantages of biodegradable plastic bags: biodegradable materials are mainly made of PLA and PBAT blended together, PLA and PBAT blended together to improve the toughness of PLA, showing the complementarity of the two.
Among them, PLA, Chinese name polylactic acid, raw material is mainly corn starch, obtained through fermentation and polymerization. It is a bio-based and renewable biodegradable material, which is completely biodegradable and can be processed by thermoplastics. In addition to being biodegradable, products made from PLA also have high strength, high transparency, good heat resistance and high plasticity. The more PLA content, the stronger the pearlescent color of the product surface and the smoother the handfeel. PLA has anti-bacterial and anti-mold effects, and can be directly loaded with food.
PBAT is a copolymer of butylene glycol para-adipate and butylene glycol terephthalate, which has excellent biodegradability and is one of the very active and marketable degradable materials in biodegradable plastic research.
