What You Can and Can't Put in a Microwave
Plastic, including Tupperware
While some plastic containers are safe for microwave use, a few should be avoided. Single-use plastics like those for yogurt, cottage cheese, and some other foods should never be microwaved. The same rule applies to plastic takeout containers that do not clearly state they are microwave-safe. Additionally, cracked, old, or discolored plastic containers are not suitable. However, plastic containers intended for long-term use, such as Tupperware, are generally safe for microwave heating.

Paper Towels
Most paper towels are microwave-safe. You can even use them to cover certain foods to prevent spattering during cooking or reheating. When using paper towels in the microwave, it is best to work in shorter intervals, allowing for frequent checks on both the food and the paper. Avoid using recycled paper towels, those with prints, paper lids, and brown paper bags, as these could pose safety hazards.
Ziploc Bags
According to Ziploc, their food storage bags can be safely used for defrosting or reheating in microwaves when the label directions are followed. If you prefer a different brand, ensure they are labeled as microwave-safe and follow the instructions. If you are uncertain about the bag type or do not have the directions, err on the side of caution and do not microwave the bag.
Cardboard
Even though you can microwave paper plates and towels, cardboard should not be treated the same way. Cardboard may contain glues, waxes, and other materials that present safety risks in the microwave. Some cardboard takeout boxes even have metal handles or fasteners that can create sparks and lead to fires. To ensure safety, always remove food from cardboard containers and place it on microwave-safe plates or bowls.
Metals, including Stainless Steel and Aluminum Foil
Items made of steel, iron, copper, or other metals should never be placed in the microwave. Metal surfaces reflect microwaves, increasing heat within the microwave and potentially causing fire hazards. If you have leftovers in a metal container, transfer the food to a microwave-safe container.
As for aluminum foil, although it can technically be microwaved, it should remain flat. Wrinkles or crumpled foil can lead to arcing, which creates electric sparks that may damage your microwave or start fires. Food wrapped in aluminum foil may not cook or reheat well, as the foil reflects microwaves instead. Each microwave varies, so consult your manual to determine aluminum foil’s safety in your appliance. When in doubt, avoid using any metal in your microwave.
How to Know if Something is Microwave-Safe
While general guidelines pertain to microwave-safe containers, there are exceptions. If you're unsure if an item is safe for microwave use, check the back or bottom for a microwave-safe label or symbol. If there is no label, examine the material from which the item is made, as this can help you determine if it's safe. If you cannot identify the material, remember: when in doubt, leave it out. This helps keep your microwave in excellent condition for years to come. Learn more about how to use your microwave.
Can You Put a Paper Bag in the Microwave?
What happens if you put a paper bag in the microwave? Is it harmful to food, or is there a fire risk? Despite their convenience, paper bags are not recommended for microwave use. In this article, we will explore why you should avoid microwaving paper bags.

What Will Happen If You Put a Paper Bag in the Microwave?
While paper bags are widely used to carry groceries, pack lunches, or hold snacks, it is unsafe to microwave them.
Microwaves are efficient at heating, but the high temperatures they produce present a significant risk when paper bags are heated. Unlike containers specifically designed for microwave use, ordinary paper bags are not built to withstand such intense heat.
Microwaving a paper bag can result in several hazards:
- Fire Risk: The primary concern is fire risk. Paper bags are not designed for high microwave temperatures. As the paper heats, it can dry out, smoke, and eventually ignite, posing a severe safety threat.
- Fumes and Toxins: Exposure to high temperatures can cause paper to break down and release harmful fumes and toxins, contaminating your food and harming your health if inhaled.
Why Paper Bags Are Not Suitable for the Microwave
Understanding the science behind the risks associated with microwaving paper bags is essential for safe food handling. Here is a closer look at the materials and properties that render paper bags incompatible with microwave heating:
Material Composition
- Regular paper bags primarily consist of cellulose fibers, which are highly flammable. Under high microwave temperatures, cellulose can undergo thermal decomposition, releasing heat and volatile gases that may ignite.
Lack of Heat Dissipation

Unlike microwave-safe containers such as glass or ceramics, paper bags do not effectively conduct heat. Instead of distributing heat evenly, the heat can concentrate in certain areas, creating hotspots that can significantly raise the risk of fire.
Unpredictable Content
- The dangers of microwaving paper bags extend beyond the paper itself. Some may contain chemicals, inks, or dyes used in manufacturing. Exposure to high temperatures can cause these additives to break down and emit harmful fumes.
Alternatives to Using Paper Bags in the Microwave
Given the risks posed by paper bags, exploring alternative methods for heating food is crucial. Below are some safe and effective options.
Microwave-Safe Containers
Investing in a set of microwave-safe containers made of glass, ceramic, or certain plastics is essential. These materials are designed to handle high temperatures and distribute heat evenly.
Benefits:
- Ensures even cooking and reduces the risk of burning.
- Decreases the chance of fire or harmful fumes being released.
- Available in various sizes for different food items.
Tips:
- Look for a microwave-safe symbol on labels.
- Avoid cracked or scratched plastic containers.
- Consider investing in lidded containers for reheating leftovers.
Transfer Food to a Plate
If you need to heat food from a paper bag, safely transfer it to a microwave-safe plate.
Benefits:
- Eliminates fire and fume risks associated with paper bags.
- Allows for even heating of food.
Tips:
- Choose an adequately sized plate.
- Avoid plates with metallic patterns that can spark.
- Ensure the plate is clean and intact.
Opt for a Different Container from the Start
When packing lunches or preparing snacks, consider reusable containers designed for microwave use. These containers provide:
- Safety: They are microwave-safe to prevent transfer issues.
- Diversity: They can be used for refrigerator or freezer storage and reheated in the microwave.
Prioritizing safety and using proper alternatives ensures you can avoid the risks of using paper bags in the microwave. Your health and safety are worth the extra effort of choosing microwave-safe containers.
Conclusion
In conclusion, while paper bags are convenient for carrying food, they pose significant risks when placed in the microwave. Understanding these dangers and adopting safe alternatives, like microwave-safe containers or transferring food to plates, ensures that your meals are heated effectively and without issue.
