Polylactic acid(PLA) is a new biodegradable material that uses starch raw materials which is extracted from renewable plant resources (such as corn). Starch raw material is saccharified to get glucose, it fermented by glucose and certain strains to produce lactic acid with high purity, then a certain amount of PLA is synthesized by the method of chemical synthesis. It has good biodegradability, and after use that can be completely degraded by microorganisms in nature, eventually generating carbon dioxide and water, which does not pollute the environment and is very beneficial to environmental protection.So as we all know，PLA is recognized as environmentally friendly material.
With the global promotion of plastic restriction,PLA is increasingly applied in various types of plastic products, such as packaging bags, disposable meal boxes and non-woven bags.
PLA nonwovens can be 100% degradation in the natural environment, and good applicability, not only suitable for artificial sewing, but also suitable for ultrasonic welding non-woven bag making machine, but because of the capacity is limited, so the price is higher than PP non-woven , so the market acceptance is not high, but believe that with the improvement of the PLA production technology and the expansion of production scale, the PLA will become the main raw material of packaging products.
