Polylactic acid (PLA), which is eco-friendly, is absolutely harmless to the human body. This feature makes polylactic acid (PLA) unique advantages in the field of disposable tableware, food packaging materials and other disposable products, such as PLA cups, PLA cutlery, PLA straws, PLA Stirrer, PLA tableware set, etc. The modified PLA materials, and some even have a heat-resistant temperature of more than 100 degrees, can be used as microwave tableware materials. PLA has good biodegradability. This is very beneficial to environmental protection and is recognized as an environmentally friendly material. Ordinary plastics are treated by incineration and cremation, which causes a large amount of greenhouse gases to be discharged into the air, while polylactic acid plastics are buried in the soil to degrade, and the carbon dioxide generated directly enters the soil organic matter or is absorbed by plants, and will not be discharged into the air. PLA tableware can be completely biodegradable and also meets the high environmental protection requirements of all countries in the world.
