Styrofoam is a foam plastic material popular for its insulation and is used for packing food and beverage. It's quite common to receive food in Styrofoam containers when ordering from restaurants. Often after ordering food, you may find it cold and want to reheat. A simple solution is to microwave it.

Before we answer the question "can you microwave Styrofoam?", let's understand what Styrofoam is.

What is Styrofoam?

Styrofoam is not a true plastic but is a type of polystyrene foam. It is typically made from a mixture of polystyrene and nitrogen, which is then molded into a shape and cooled. Styrofoam is popular due to its lightweight nature, affordable cost, and high resistance to heat and chemicals.

Can you Microwave Styrofoam?

Styrofoam melts when heated and releases small toxic particles harmful to the body. When the food cooks in a microwave like Nostalgia RMO4AQ, it heats from the inside. The heat from the food can burn the Styrofoam, which may set the microwave on fire.

Reasons Why Microwaving Styrofoam Is Not A Good Idea

Microwaving Styrofoam is not safe. This material remains stable for normal use but at high temperatures Styrofoam begins to melt or break down. It releases toxic chemical styrene that can leach into your food.

If looking for a microwave you can consider buying the Sharp R-21LCFS Medium-Duty Commercial Microwave as its customer reviews claim that it is simple to operate, spacious, and easy to maintain. It comes with a handy "on-the-spot" reference over the timer with recommended heating times for a variety of popular foods.

How to Safely Microwave Food in a Styrofoam Container?

You should never heat food in a standard Styrofoam container. Some good quality microwave-safe Styrofoam containers pass the FDA standards for hygiene and consumption. This makes them convenient to use in a microwave.

The special Styrofoam consists of safer materials and fewer hazardous compounds. They are also relatively resistant to heat as compared to the standard Styrofoam. Another alternative is to use microwave-safe utensils that can heat the food without putting you or the food at risk.

A built-in microwave is a great appliance for your kitchen. It is installed within a cabinet space over or under the kitchen counter. Go through our blog on built-in microwaves to learn more.

How Can You Tell if Styrofoam is Microwave Safe?
