Can paper lunch boxes be microwaved

Shouldn't

Paper lunch boxes should not be heated in the microwave. This is because the box has a low ignition point, and the microwave oven will produce a higher temperature when it is running, which may cause the box to burn and even damage the microwave oven. In addition, the inside of many paper lunch boxes are coated with plastic film or ink patterns, which may release harmful substances at high temperatures. Therefore, heat-resistant containers designed for microwave ovens, such as glass, ceramic or heat-resistant plastic, should be used for heating to ensure food safety and safe use.
