Can You Microwave Paper Plates? Is It Safe?

A microwave is a convenient tool for quickly heating up food. But is it safe to microwave certain items, such as a paper plate? Can you microwave paper plates?

You can microwave paper plates, as long as they are made of 100% paper. It is not safe to microwave paper plates that contain thin layers of plastic. The added plastic could cause a fire or emit toxic fumes.

The safest way to know if your paper plate is safe for the microwave is to ensure the label on the packaging says it is ‘microwave safe.’ If you don’t have the packaging, the paper plate should generally be safe in the microwave as long as there is no plastic coating on the plate.

Most other paper products are also safe in the microwave, such as wax paper, paper bowls, paper towels, and parchment paper. However, do not use brown paper bags in the microwave as they can’t take much heat – they can catch fire or emit toxic fumes.

Read on to learn more about microwaving paper plates and the types of paper plates you can use.

Can You Microwave Paper Plates?

Some curious office workers wanted to know if regular copy paper would catch fire when placed inside a microwave oven. So, they experimented on a sheet of copy paper, put it inside the oven, and turned the machine on.

The paper didn’t catch fire. It just turned into a warm sheet of paper. Their experiment demonstrates that it is safe to microwave paper products, such as white paper towels, parchment paper, white copy paper, and white paper plates.

So, can you microwave paper plates? Yes, they are 100 percent microwave safe! In fact, you can also microwave napkins and towels.

While this is true, there are paper plates coated with plastic and paper towels that aren’t entirely free from plastic. You can’t microwave these paper items. Therefore, the National Sanitation Foundation International highly recommends the use of paper products labeled as ‘microwave safe.’

According to the NSFI, parchment paper and wax paper can be microwaved, too, along with microwave cooking bags. Microwaving paper products are fine as long as they are made of 100 percent paper and are not coated with plastic. Some have used paper towels to cover the food that they will heat in the oven, and nothing bad happened.

To be safe, just make sure that the food is on the paper plate before putting it inside the oven. It will also help if there’s a glass turntable inside the microwave oven. Also, ensure that the glass turntable is at room temperature. If it is too hot, the paper plate might be charred by the excessive heat.

You can also try placing a paper plate and a bowl of water inside the microwave. Set the oven on high for a minute and turn it on. Check the temperature of the paper plate afterward. If the paper plate is too hot to the touch, it is not microwavable.

Microwaving Paper Plates – Is It Safe?

So again, can you put paper plates in the microwave? Yes, paper plates are safe to use in a microwave oven. Most people want the utmost convenience in cooking and reheating food. That’s why they use the microwave oven.

However, the type of container you’ll use inside the microwave plays a vital role in cooking or reheating food. If you use containers not suitable for microwave ovens, they could melt, warp, catch fire, or ruin your food. While paper plates and other paper products are generally safe to use when reheating food in any microwave oven, always take the necessary precautions to be safe.

For the best and safest results, just stick to plain white paper plates. You will increase the chances of accidental fires if you use non-white, decorated, or printed paper plates. The additional colors and prints might contain chemicals that could leach into the heated food.

Other safe, microwavable paper products include parchment paper, plain paper bags, paper napkins, paper towels, and wax paper. Brown paper bags are a no-no, along with newspaper and recycled paper.

Recycled paper may contain hazardous chemicals and certain materials that can change the composition of food when they come into contact. Brown paper bags are potential fire hazards because they catch fire easily. Inks in newspapers may also contain toxins that can leach into the food.

If you want to use paper plates in the microwave oven safely, consider the following tips in cooking or reheating food:

If you are reheating a slice of oily and greasy pizza, bacon, steak, or chicken, put it in a stack of two or three paper plates. The extra plate layers will absorb the excess grease. They will also provide stable support to prevent the food from falling as you remove it from the oven.

As an extra measure of safety, prepare a dish plate before removing the food from the oven. Remove the food from the oven by slowly sliding the paper plates onto the dish. Even if the paper plates bend because of the food’s weight, the dish will support it, and the food won’t fall off.

Will a Paper Plate Inside a Microwave Catch Fire?

Can you put paper plates in the microwave without catching fire? If you take the necessary precautions, the paper plate will not catch fire inside a running microwave oven. There is no danger of the paper plate catching fire if you are only reheating food. Reheating foods in this oven takes only a few short seconds and not even a minute.

In reality, the paper plate wouldn’t even feel warm to the touch, except for the part where the plate is in direct contact with the heated food. No one has yet tried to put a paper plate inside a running oven for days to see if it will catch fire.

However, in principle, it wouldn’t. Objects that do not contain any moisture cannot absorb the radio frequencies that are being emitted by a running microwave oven. In other words, if the paper plate is completely dry, it would not be able to absorb the energy emitted by the oven. Therefore, there is no chance that it could catch fire inside a running microwave oven.

Microwave ovens are designed to run in spurts, not in long hours. Running it continuously for an hour might overload its electronics and cause a short circuit. The oven may even explode.

Another thing is that paper does not conduct electricity. That alone will show you that it won’t catch fire inside a running microwave oven. However, if you put a spoon or fork on top of the paper plate, that is a different matter. Steel will get overly hot if ‘cooked’ inside the oven. Its heat will transfer to the paper, and the paper will catch fire, and so will the oven. So, don’t do it!

The same happens with decorative paper plates. If you put a paper plate with silver decorations on the sides inside a microwave oven, the decorations’ silver content will get hot. Given enough time inside the oven, that may set the paper plate on fire.

Someone has tried placing a silver foil on top of a paper towel and put these two items inside a microwave oven. He turned the machine on, and in just 20 seconds, sparks came from the silver foil, which then set fire to the paper towel.

So, if you just place a plain paper plate alone in the oven and run it, nothing will happen. However, if you put other things that can conduct electricity, such as any kind of conductive metal, aside from the paper plate, there’s a high risk of setting the paper plate on fire.

What Can Cause a Paper Plate to Catch Fire in the Microwave?

There are situations wherein paper products like paper plates will burn inside a microwave open. For instance, if heating is stretched more than the recommended time, the paper plate may catch fire.

Thin paper plates could also catch fire when heated for an extended time. These types of paper products contain free and bound water, which can absorb microwave energy. Thin paper plates have a flame point, which will cause burning at the plate’s edges – if the heating time is overly extended.

While plain white paper plates are safe to use in a microwave oven, other paper products aren’t. If they contain decorative designs, traces of metal, inks, and other conductive and toxic materials, they are not microwavable.

Certain inks are flammable, so when paper plates with inked lines are put inside the microwave, they could burn. Just ensure not to let a paper plate with inked lines stay in the microwave for more than 30 seconds. If you need to, keep a close eye on it.

It is also unsafe to cover paper-plated food with plastic wrap. When you microwave food longer than required, the plastic wrap may melt, and its contents may leach into the food, making it toxic and dangerous to eat.

Which Paper Plates Are Not Microwavable?

So we’ve answered the question, “can you microwave a paper plate?”. Next, let’s look at which paper plates are not microwavable. There is a way by which you can determine if a paper plate is microwavable.

The Food Safety and Inspection Service of the United States says that there is no problem in microwaving paper plates, parchment paper, paper towels, and paper napkins. But there’s a caveat: as long as they are white and don’t have prints.

Therefore, printed paper plates are not microwavable. The reason is obvious–the ink may melt, and its chemicals may leach into the food being heated. Paper products with foam insulation are also not safe to use in a microwave. The foam may melt and leach into the food.

Paper plates that contain metal decorations or traces of metal are not safe to put inside a microwave oven. The paper plate’s metal contents will get too hot, and the heat may set the paper on fire. They can also cause sparks that will set the plate on fire.

Recycled paper is not safe as well. You don’t know what kind of paper source the recycled paper is made of. Its raw material could be used newspapers, brown bags, paper printed with all sorts of colors, etc. And you don’t want these things to end up on the food you’re about to eat.

In short, only white, non-recycled, print-free paper plates should go inside a microwave oven. Decorated paper plates, paper plates with foam insulation, and those made of recycled paper and metallic elements should never be microwaved.

Conclusion – Can You Microwave a Paper Plate?

So, to recap, can you microwave paper plates? Yes, you can microwave most paper plates along with other paper products, such as wax paper, paper bowls, paper towels, and parchment paper. Just ensure that the paper plate is made of 100% paper.

Some paper plates are coated with thin layers of plastic, which melts under high heat. The safest way is to use paper items that have ‘microwave safe’ labels.
