Polylactic acid is produced by fermentation with starch based biomass such as corn and potato or straw cellulose as raw materials. Lactic acid is prepared into cyclic dimer lactide, and then lactide is ring opened and polymerized to produce polylactic acid. As a biodegradable material, polylactic acid has the characteristics of environmental protection, non toxicity and degradability. It is the biodegradable material with the largest output, the widest application range, the highest cost performance and the closest to petroleum based polyester in the international market. It has a large-scale demand in the fields of plastic industry, packaging industry, manufacturing industry and pharmaceutical industry.
Product features: polylactic acid has environmental protection, non toxicity, antibacterial, flame retardant and good biocompatibility. It can be completely biodegradable under the condition of industrial composting.
