Can You Put Styrofoam In The Microwave?

Going out to dinner can be such a treat. It’s nice having someone else take care of preparing the food, setting the table, and washing the dishes. Sometimes the portions are way too big to eat in one sitting. Luckily almost every restaurant has styrofoam containers to pack your leftovers up to take home with you. This might have you wondering, can you put styrofoam in the microwave?

Picture this, you go out to eat and order a delicious pasta entree. It arrives at the table in a giant bowl loaded with melted cheese and all the fixings. There’s a side of garlic bread and salad. It tastes delicious but you can only eat so much, so you get the leftovers packed up to take home.

The next morning when you’re getting ready for work you think about the leftover pasta in your fridge. Perfect, there’s something to bring for lunch today. However, can you put styrofoam in the microwave in the lunchroom?

The answer to this question all depends on what type of styrofoam you have. There are two types of styrofoam and one is safe to be heated up, while the other isn’t. Today we’re going to go over the difference between the two so you know if the container you receive your food in is safe to go in the microwave.

How Do You Know If Styrofoam Is Microwave Safe?

You brought that leftover pasta with you to work today and you must be wondering “how do you know if styrofoam is microwave safe”? There are a few indicators to look for on the label so you know if the container you received is microwave safe. Look for any of the following labels on the bottom of your container:

  • Micro
  • Microwave safe
  • “Warm waves” symbol

If you see any of these labelled on the bottom of your styrofoam container then you can safely reheat your leftovers in that container. Even though you can safely reheat these styrofoam containers, it’s still a good idea to keep their time in the microwave short. Don’t heat styrofoam up for more than 60 seconds at a time.

The original type of styrofoam that was invented is made out of polystyrene which is basically a plastic product.When asked “can styrofoam be melted in the microwave?” The answer could always lead to a yes if you are not careful. This is because styrofoam doesn’t react very well to high heats.

Modern types of styrofoam can be microwaved because they are made from safer materials. This doesn’t mean that you should leave them in the microwave for longer periods of time. If you are reheating your food in a styrofoam container try to always keep it to a short interval.
