For whether the biodegradable plastic container can be heated in the microwave oven, we need to understand the heating principle of the microwave oven first. Microwave ovens heat food by vibrating water molecules in food through microwave radiation to generate heat. For plastic containers, the high temperature generated by the microwave oven is easy to cause deformation, melting and other problems, so it is necessary to distinguish plastic products. For biodegradable plastic containers, because the material composition is softer, its heat resistance is weak indeed . Therefore, if the biodegradable plastic containers are heated in the microwave oven, it may cause deformation, melting and other problems, so it is not recommended to use the biodegradable plastic containers for microwave heating.
