The Safety Question: Can You Microwave Takeout and Pizza Boxes Made of Cardboard?

The answer is it depends. If the cardboard says it’s microwaveable, then you can put it in along with your food. But if it says otherwise, do not proceed just to be safe.

Do not microwave the cardboard or box if it has any metal or wax on it. You should also put food in the container, and then you can microwave the whole thing at a low temperature. And that would be the safest way here.
