What is Can Plastic Go into a Microwave?
When it comes to heating food in the microwave, one of the most common questions that come to mind is whether plastic containers are safe to use. The answer is not a straightforward yes or no, as it depends on the type of plastic and its compatibility with microwave radiation.
Understanding Plastic Types and Their Microwave Safety
Plastics are made from a variety of materials, each with its own set of properties and characteristics. Some plastics are designed to be safe for microwave use, while others can melt, warp, or even catch fire when exposed to microwave energy.
- For example, polycarbonate (PC) and polyethylene terephthalate (PET) plastics are commonly used in microwave-safe containers, as they can withstand high temperatures without degrading.
- On the other hand, plastics like polyvinyl chloride (PVC) and polypropylene (PP) can melt or deform when heated in the microwave, making them unsuitable for microwave use.
Checking for Microwave-Safe Plastic
To ensure that your plastic container is safe for microwave use, look for the following indicators:
Check the container’s label or packaging for a symbol that indicates it is safe for microwave use. This symbol is usually a microwave-safe logo or a notation that says “microwave-safe.” Additionally, check the manufacturer’s website or contact their customer service to confirm the plastic’s compatibility with microwave radiation.
As we explore the world of microwave-safe plastics, it’s essential to remember that even if a plastic container is labeled as microwave-safe, it’s still crucial to follow proper heating guidelines and usage instructions to avoid any potential risks or damage. This brings us to the next crucial aspect of microwave safety: understanding the basics of microwave safety and plastic compatibility.
Understanding the Basics of Microwave Safety and Plastic Compatibility
Now that we’ve established what types of plastic are safe to use in the microwave, let’s dive into the fundamental principles of microwave safety and plastic compatibility. This will help you make informed decisions when it comes to choosing the right containers for your cooking needs.
The Science Behind Microwave Safety
Microwaves work by exciting water molecules in food, causing them to vibrate and generate heat. This process is called dielectric heating. However, not all plastics are created equal, and some can melt, warp, or even catch fire when exposed to microwave energy. This is because certain plastics, such as polycarbonate and polyethylene, have a low melting point and can become brittle or discolored when heated.
- For example, a polycarbonate container with a BPA-free label may still be prone to melting or warping in the microwave due to its inherent properties.
- On the other hand, polypropylene and polyethylene terephthalate (PET) plastics are generally considered safe for microwave use, as they have a higher melting point and are less likely to degrade.
Labeling and Certifications: What Do They Mean?
When shopping for microwave-safe plastic containers, you may come across various labels and certifications, such as “BPA-free” or “microwave-safe.” While these labels can provide some assurance, it’s essential to understand what they really mean. BPA-free simply means that the container does not contain bisphenol A, a chemical that has raised health concerns. However, this does not necessarily guarantee that the container is safe for microwave use. Look for specific certifications, such as the UL (Underwriters Laboratories) or ETL (Intertek) mark, which indicate that the container has undergone rigorous testing and meets safety standards.

With a solid understanding of the basics of microwave safety and plastic compatibility, you’re now ready to move on to the next step: safely checking and using plastic containers in the microwave. By following the guidelines outlined in the next section, you’ll be able to enjoy your favorite microwave dishes with confidence and peace of mind.
How to Safely Check and Use Plastic Containers in the Microwave
Now that we’ve covered the basics of microwave safety and plastic compatibility, it’s time to dive into the specifics of how to safely check and use plastic containers in the microwave. This is where many people go wrong, but with a few simple steps, you can ensure that your plastic containers are safe for reheating and cooking.
Checking for Microwave-Safe Symbols
First and foremost, you need to check if your plastic container has the necessary symbols or markings that indicate it’s safe for microwave use. Look for the words ‘microwave-safe’ or ‘BPA-free’ on the packaging, and also check for the symbol of a microwave oven with a wavy line through it. This symbol is an international standard that indicates the material is safe for microwave use.
- Check the packaging or label for any specific instructions or warnings about microwave use.
- Also, inspect the container for any cracks, chips, or other damage that could compromise its safety.
Using the ‘Water Test’ Method
Another way to test the safety of your plastic container is by using the ‘water test’ method. Fill the container with water, and then heat it in the microwave for 30 seconds to 1 minute. If the water is hot but the container doesn’t warp or melt, it’s likely safe for use. However, if the container does warp or melt, it’s best to err on the side of caution and discard it.
With these simple steps, you can ensure that your plastic containers are safe for use in the microwave. By checking for the right symbols and using the ‘water test’ method, you can avoid any potential risks and enjoy the convenience of reheating and cooking with plastic containers. But, what are the key benefits and best practices of using microwave-safe plastic containers?

Frequently Asked Questions
What is microwave-safe plastic, and how does it relate to microwaving cans?
Microwave-safe plastic refers to a type of plastic that is designed to withstand microwave heating without releasing toxic chemicals or catching fire. However, when it comes to microwaving cans, it’s essential to note that even if the can is made of microwave-safe plastic, it’s not recommended to heat food in metal cans in a microwave oven. The metal can cause sparks and potentially start a fire.
How do I check if a can is microwave-safe?
To check if a can is microwave-safe, look for the following symbols: a microwave-safe icon (a wave pattern), a number (such as 2 or 5), or a statement indicating that the can is safe for microwave use. You can also contact the manufacturer or check the product label for more information. If in doubt, it’s always best to err on the side of caution and avoid microwaving the can.
Why can’t I microwave a metal can?
Metal cans can cause sparks and potentially start a fire when heated in a microwave oven. This is because the metal can absorb microwave energy and cause it to build up rapidly, leading to a spark or even a fire. Additionally, the metal can also cause the microwave oven’s magnetron to malfunction, leading to a range of issues, including reduced performance and potentially even a fire hazard.
When can I safely microwave a plastic container?
You can safely microwave a plastic container if it’s specifically designed for microwave use and is made of a microwave-safe material.
