Can the degradable lunch box be heated in a microwave oven?

Pulp lunch boxes such as sugar cane and wheat stalks can be heated in a microwave oven up to 220°C. Light salads sold in convenience stores are all degradable disposable pulp lunch boxes. It is possible to heat it in the microwave. But dont put in the microwave oven with plastic lid. The ignition point of the plastic lunch box is relatively low. In addition, toxic substances will be released after heating, which will affect food safety.


Meal boxes based on cornstarch cannot be heated in a microwave oven. Plastic PP is added to the inside, which is also toxic when heated.


In the case that it is difficult to distinguish which kind of lunch box, it is best not to lightly heat it in a microwave oven.
