When customers choose products, they first pay attention to whether the raw materials of the products are healthy and safe. Fully biodegradable PLA stics are widely used, such as PLA , which can be used in packaging, disposable appliances, agricultural and medical fields, etc., which fundamentally solves the environmental pollution and hazards of traditional PLA stics. So what raw materials are fully biodegradable PLA stics made of? Fully biodegradable PLA stics are mainly made from natural polymers (such as starch, cellulose, chitin) or straw and other agricultural by-products, which are fermented by microorganisms or synthesized with biodegradable polymers, such as thermo PLA stic starch PLA stics and aliphatic polyesters. , polylactic acid, starch/polyvinyl alcohol, etc. are all such degradable PLA stics. What is the heat resistance of fully biodegradable PLA stics? For example, PLA has excellent heat resistance, and its heat distortion temperature is close to 100°C. After modification, it can exceed 100°C (the heat resistance is the best among fully biodegradable polyesters), and it can be used to prepare food packaging such as hot and cold drinks and lunch boxes. products. With the increasing awareness of environmental protection among the Chinese people, as well as the improvement of environmental protection laws and their implementation rules, fully biodegradable PLA stic products will gradually re PLA ce traditional PLA stic products.
