Can You Microwave Paper? What Kind of Paper Can You Microwave?
There are numerous circumstances in which you might want to put paper in the microwave, including when it is sheets of paper, a wet book, paper towels, or paper plates and cups.
But given that paper can catch on fire easily you may be wondering can you microwave paper?
It’s a good idea to ask this question, not only due to the potential fire hazard but also because paper surprisingly can contain chemicals that are harmful to people.
It is safe to microwave paper when the paper is lying flat, but you should always keep an eye on it. Paper towels, sheets of paper, and plates and cups fall under this category. However, when scrunched up paper can easily combust in the microwave and set on fire.
Microwaving food or beverages in or on paper comes with additional health risks. While dangerous substances like BPA and styrene don’t appear to seep into food or beverages from paper, the bleaching process to make paper white can produce toxic substances called dioxins, which are likely human carcinogens.
The health risk connected to food and paper will be examined in greater detail later. For the time being, let’s examine what happens when paper is microwaved and under what conditions it can catch fire.

Can You Use Paper in the Microwave?
Well, the short answer to this is that it depends on the type of paper you’re using in the microwave. Additionally, you need to consider how the paper product will be used.
When used inside a microwave, fragile, thin paper poses a risk of catching fire because the thin layers heat up quickly and have a low density, which can cause the paper to catch fire after a few seconds. Although thicker paper can be heated, microwaved food is highly likely to cross-contaminate with chemical compounds.
- Newspaper: Due to its thinness, the paper can only withstand brief heat exposures before catching fire. Additionally, since newspaper ink can bleed into food, it is extremely unhealthy to eat.
- Paper towel: For microwaved food covers, paper towels are frequently used. Food moisture absorbs into the paper, reducing the risk of fire.
- Parchment paper: Because parchment paper is made for oven use, you can microwave them without much risk.
- Tissue paper: Toilet paper, facial tissues, and sanitary napkins are a no-no. When exposed to intense heat, the paper’s thinness makes it easily flammable.
- Utensils: Paper utensils like paper plates and cups are typically thick and difficult to set on fire. They won’t catch fire if used inside an oven for an extended period of time.
- Wax paper: Wax papers can be microwaved without issue because they were designed to be used in an oven. Can you put wax paper in the air fryer?
The thickness of the paper, which significantly affects its risk of catching fire, is crucial for microwave safety. Make sure you don’t microwave paper products for longer than five minutes because doing so can burn the edges and make them more likely to catch fire.
Fire is a risk that cannot be avoided, but it is also important to talk about the risk of chemical contamination when heating food that comes into contact with paper products.
What Happens When You Microwave Paper?
There isn’t a lot of information online about what happens to paper in a microwave. Can paper catch on fire in the microwave, and under what circumstances is it okay to do so?
So I made the decision to carry out some experiments on my own. Brown paper bags and some white paper were microwaved. I tested them in the microwave both flat and then scrunched up, watching to see if they would ignite or experience any other negative effects.
Even though flat paper can reach temperatures of over 100°C (212°F) in a microwave, it is unlikely to catch fire when laid flat. However, when it is compressed, it can become hot enough in some spots to ignite the whole thing.
The paper begins cooling down incredibly quickly as soon as the microwave is turned off. If you plan to microwave paper for some time, keep in mind this fact.
Shorter microwave bursts are much safer than long ones.
Paper towels, cardboard, paper plates, and paper cups are all examples of items that fit this description.
Therefore, if you want to microwave paper, you should keep it as flat as you can.
Is It Safe to Microwave Paper?
In a microwave, solid paper does not easily catch fire. The risk of a fire starting is higher with single-layer or thin, flimsy paper tissues.
The thin surface area heats up quickly and catches fire. Thin paper has a high likelihood of catching fire after only 5 seconds in the microwave, which could harm your oven.
To avoid bending easily, look for paper that is thick, sturdy, and unflimsy. Food trays, cups, and bowls can often be found at grocery stores and fast food restaurants. These items are typically thick enough to withstand both the weight of the food inside and transportation.
In a microwave, disposable paper containers usually heat up and don’t burn as easily. Although thick paper can be safely microwaved for up to 5 minutes at a stretch, the glue thats holds a Starbuck’s paper cup and the coating that lines a McDonald’s wrapper make them risky paper products to heat food in the microwave
Can You Microwave Paper Safely?
Be extremely careful when handling food that has been microwaved in paper because the paper can become extremely hot. To safely remove hot items from the microwave, it is advised to wear gloves.
After removing the paper from the oven, its surface is typically still very warm for a while. Before using the paper container, allow it to visually cool off.
Your choice of paper will determine whether or not it can be used safely in the oven. Paper that is prone to tearing or breaking is generally not a good choice for a microwave.
On the other hand, you can use thick paper inside an oven that can withstand greater pressure and doesn’t tear easily. To avoid the paper drying out and catching fire, paper should always be used sparingly and with caution.
How Long Can You Microwave Paper?
Although there is no specified amount of time for microwaving paper, you might only want to microwave it for no more than five minutes on your typical food bowls and holders.
The food will typically be warm and ready to eat in 5 minutes or less. In areas where the paper is thin, microwaving it for longer than five minutes may cause it to burn.
On the other hand, wax paper and parchment paper are intended for use in ovens. They can be utilized inside of an oven for baking and other forms of cooking.
More than 30 to 45 minutes at a time can be spent using cooking papers. These particular types of paper are perfect for heating in a microwave because they are coated with a special wax that enables the paper surface to get heated easily without catching fire.
Tips to Safely Microwave Paper
In contrast to some paper products, which can be heated in the microwave without risk, others may catch fire or have chemical bonds break, which could contaminate food.
- To lessen the chance of a fire starting because of extreme heat fluctuations, microwave paper products on medium heat or 50% power.
- Aim for 176 degrees Fahrenheit, which is 80 degrees Celsius, in the oven. The paper will heat up to the ideal level without burning at this temperature.
- Always remove any tissues or napkins that may be around the food before placing anything in an oven, and only use thick bowls and trays.
- To speed up cooking time by capturing steam and more effectively heating the food throughout, try covering the food with a microwaveable cover.
- When taking the food out, always wear heat-resistant gloves. If touched with bare hands, the paper containers’ surface can become extremely warm, release steam, and result in burn injuries.
- Reusing paper containers in the microwave is not advised. When heated, paper becomes brittle and dry. Even thick paper can catch fire after repeated use.
Can You Microwave Sheets of Paper?
It’s possible that you accidentally wet a book, wet an important piece of paper, or tea-stained the paper and need it to dry quickly. Can you microwave sheets of paper or will they catch on fire?
Paper can be microwaved, and as long as it is lying flat, it won’t likely catch fire. Don’t put the paper in the microwave for more than two minutes at a time, and keep an eye on it while it’s there.
If you must microwave your paper for a longer period of time than 2 minutes, break it up into several shorter bursts of 30 to 60 seconds, allowing the paper to cool between each one to reduce the risk of fire. Even shorter microwave bursts are probably preferable for smaller pieces of paper.
A few useful advice is included in this Quora article. Like these comments from Em:
Being cautious and moving slowly is essential! I quickly dry the paper in short bursts. I will perform the first time at 10 seconds if there are only a few small pieces, such as a few small jar labels. Then wait for 5 seconds, then 4 until the mixture is almost dry. But I stay put and stand right in front of the microwave. A glass plate is what I also use.
Can You Set Paper on Fire in the Microwave?
Is it actually possible to ignite paper in a microwave, and if so, how?
I’ve found that it’s very likely to catch paper on fire in the microwave through my own experiments with paper, paper towels, and cardboard.
Flat paper is less likely to catch fire in the microwave than paper that has been crumpled up. The heat generated by the compressed areas is sufficient to ignite the entire sheet of paper.
The 13-year-old sister of my partner immediately placed her leftover McDonald’s chips in a McDonald’s bag and microwaved them for 4 minutes. THE WHOLE BAG STARTED ON FIRE!
Given that 4 minutes is unquestionably long enough to ignite paper, the top of the bag was probably scrunched up.
In my own tests, I crumpled up a brown paper bag and microwaved it. The paper began to smoke after just one minute, and at the two-minute mark, it caught fire completely.
So yes, it is absolutely possible to ignite paper in a microwave.
Can You Microwave Paper Towels?
To prevent food from drying out or splattering, many people place paper towels on top of their food. Alternatively, some individuals place their food on paper towels rather than a plate. But can you microwave paper towels? Is it safe?
Paper towels can be placed on top of or beneath food in the microwave as long as they are flat and not scrunched. However, paper towels should never be used in the microwave because they could contain carcinogenic dioxins (from the bleaching process).
Can You Microwave Coated Or Colored Paper Plates?
No, paper plates that are coated, decorated, or dyed pose a risk despite being safe to microwave when made of plain white. The likelihood of these catching fire is higher.
Additionally, a 2018 report by the Center for Environmental Health on disposable foodware reveals that decorated plates are more likely to contain hazardous chemicals like PFAS (per- and polyfluoroalkyl substances). Teflon is produced using these substances.
As food heats in the microwave, PFAS from the dish may seep into it. In addition, a CDC review reveals that PFAS may have negative health effects at high exposure levels.
Frequently Asked Questions
How Long Can a Paper Plate Be Microwaved For?
You don’t need to worry about how long the paper plate is in the microwave if it is marked as microwave-safe; you can use it normally. As long as the food requires, continue to heat it in the microwave.
The less safe a plate is, however, the longer you leave it in the microwave. We advise you to not microwave your paper plate for longer than five minutes if you want to keep it 100% safe and durable.
Are Paper Plates Bad for You?
The type of paper plates in question will determine this because different brands and types use various materials.
Paper plates that are made to be completely safe and are marked as being BPA-free should be fine.
However, some paper plates contain a PFAS chemical as well as BPA, which is dangerous and may have negative effects on one’s health.
Avoiding these is highly recommended. Simply use regular plates and wash the dishes, or use paper plates that are guaranteed to be chemical-free.
Are Paper Plates Bad for the Environment?
Again, this is dependent on the kind of paper plate in question.
In general, paper plates are not good for the environment. Despite being made of paper, they are typically not recyclable after being used to hold food.
Not to mention that many paper plates have a plastic coating, and some may have hazardous chemicals that leach into the environment and harm it.
There are, however, some paper plates that are completely eco-friendly and safe for the environment. These will usually be made out of materials that are completely compostable and biodegradable, and are a great option to keep using paper plates while taking care of the planet!
How Do I Know a Paper Plate is Microwave-safe?
To determine whether a paper plate is microwave-safe or not, look at the packaging is the quickest and most reliable method.
On the label, it will state whether or not it is microwave-safe. As an alternative, it might have a tiny microwave symbol, in which case it is okay to use in the microwave.
Is It Bad to Stand in Front of the Microwave?
Since radiation is generally considered to be harmful to humans, microwaves use radiation to heat food. However, don’t be concerned; there will be no harm done to you if you stand in front of a microwave.
Since the microwave is sealed off and contains all the radiation, nothing will get to you outside. Fortunately, microwaves won’t turn on unless the door is shut, so there shouldn’t be any danger at all!
Final Thoughts
Your complete guide to using paper inside a microwave is available in the aforementioned article. The quality of the paper being used should be checked before placing it inside an oven, and it should be used with caution inside a microwave.
Strong utensils and thick bowls offered by fast food restaurants can be microwaved with some degree of safety, but glues and adhesives used to make a waterproof seal can become toxic when heated beyond a safe temperature. Water can thus only be heated in paper cups for a brief period of time.
If you have used paper products in the microwave without experiencing any negative side effects, keep going with caution. When choosing the proper type of paper for use in a microwave, use common sense, and everything will be fine.
