Can You Microwave Cardboard

Ensure the absence of wax coating

Wax is used as a seal to avoid liquid spillages. The container is usually smooth. When exposed to heat, it will definitely melt hence the emission of harmful fumes. This in turn contaminated your food. So, scrutinize the pack for any wax. Additionally, ink from the colored and printed material could fall off. Remember, they are chemicals and you may be affected. Cardboard packages especially those in fast foods are meant to be temporary, not to be re-used.

Remove metal pieces if any

It’s not uncommon to find some little metallic parts in the packages. They often secure the food container. It would be lethal if one accidentally ingested a piece. The small ones can be hard to detect so if suspicious, don’t put your safety on the line. Heat the food using alternative ways.

Confirm if there’s food in the container

How can this happen? Suppose you had leftovers from a takeaway restaurant then your child takes a bite. Not being aware, you put the container in the microwave. After a few seconds, you notice it’s smoking. Switching it off, you realize there wasn’t food in the first place. Cardboard, being made from paper, will always burn when exposed to heat. Therefore, check the container just to be sure.

Heat within the shortest time

The microwave’s timer is set based on the type of food to be heated. However, it is recommended that food in cardboards shouldn’t take long.

Conclusion

It is possible to microwave food packed in cardboard. Some products will indicate if the container is microwave-safe or not so don’t overlook that part. If you decide to use the appliance, be extra careful. Inspect the cardboard to ensure there are no hidden fragments of metal.

Assuming that there’s food in the container and immediately heating it is dangerous. It gets burnt and your appliance might break down. Inquire from the attendant at the eatery where you purchased the food if that type of cardboard is microwave safe.

Caution should be observed at all times when using these home appliances. It’s up to you to choose whether to microwave the cardboard or not. However, there are more cons to doing so. The next time you carry a pack of fries home, weigh in the options and make an informed decision.
