Is It Safe To Microwave Cardboard?
Although cardboard-contained takeout or foods are considered generally microwave safe, there are a few things to bear in mind, when you plan to microwave cardboard or reheat a cardboard-contained food.
Firstly, you need to confirm that the cardboard container in question is microwave safe. Always start by checking the labeling, if the particular container is considered microwaveable, and solely use containers that are considered so.
This is because cardboards are often made from recycled materials, and the cardboard container in question may be recycled from materials that are not microwave-safe, such as metals. With this, if such isn’t stated in the labeling, confirm from the manufacturer’s website, if the container is regarded as microwave safe.
Also, do not microwave cardboard as a stand-alone or empty. This simply means your cold or excess food or drink should be inside the cardboard container when reheating, as empty cardboard when reheated absorbs heat, making it flammable.
As mentioned above, refrain from microwaving cardboard that contains metals, ink, wax, glue, or any recycled material that is considered not microwave-safe, as this could lead to the cardboard box catching fire.
Additionally, should in case the cardboard catch fire when reheated, remove the box from the microwave and use a fire extinguisher or baking soda. Do not pour water on flaming cardboard, this could lead to increased fire.
