Compostable Blister Moulding Materials PLA is made from corn, potato and other starch-based biomass  or straw cellulose as raw materials, fermented to produce lactic acid, and further purified and polymerized to prepare high-purity PLA, which is environmentally friendly, non-toxic, antibacterial, flame retardant and good biocompatibility. It can be completely biodegradable under normal composting conditions. With the largest output, the widest application range, the highest cost performance and the closest to petro-based polyester in the world, PLA will account for 70-80% of the market share of biodegradable Material. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use, and eventually generate carbon dioxide and water. It does not pollute the environment, which is very beneficial to the protection of the environment and is recognized as environmentally friendly material.
