PLA(Polylactic Acid) is an environment-friendly raw material substituting for traditional petroleum derived plastic products. Pla is a polymer made from natural organisms. It is free from dependence on petroleum resources and has good compostability and biodegradability.The biomaterial used to produce pla absorbs carbon dioxide through photosynthesis during production, thereby balancing the carbon cycle on Earth.Pla has the basic characteristics of general-purpose polymer materials, and can perform various molding processes like ordinary polymers, such as extrusion, film forming, injection molding, blow molding, and fiber molding.The product is light in weight, low in dosage and saves resources.
