Why are some Tupperware not microwave safe?
Some Tupperware plastic containers are not microwave safe because they are made with plastics that have a higher risk of leaching harmful chemicals into your food and/or they have a low melting point. Though Tupperware stopped producing containers with BPA, there are other chemicals, such as phthalates and styrene, that can transfer from microwaved containers to your food.
It’s best to follow the rules here about which containers are microwave safe and which are not. The harmful chemicals you’re exposed to by microwaving in unsafe containers can build up in your body over time. This can lead to poor health outcomes down the road.

According to Staples, all Ziploc food storage containers are microwave safe. I highly recommend checking the product packaging of your Ziploc containers to confirm this. You may have old containers or a new product that isn’t microwave safe.
Is IKEA tupperware microwave safe?
According to IKEA, their Pruta food storage containers are microwave safe. The IKEA 365+ food containers are also microwave safe (source). In addition, both of these products are dishwasher safe.
Is Rubbermaid tupperware microwave safe?
According to Rubbermaid, food storage containers in the Takealongs, Brilliance, and EasyFindLids lines have a microwave-safe base. The Rubbermaid FreshWorks containers are meant for fridge storage and are not microwave-safe.
Do you microwave Tupperware with lid on or off?
Should you microwave Tupperware with lid? In general, you should microwave microwave-safe Tupperware containers with the lid off. However, Tupperware also sells containers with microwave-safe vented lids. You must leave this vent open when microwaving sealed containers to allow the release of steam.
How long can you microwave plastic Tupperware?
Tupperware recommends not microwaving their microwave-safe containers for more than 3 minutes (source). If you need to reheat leftovers for longer, stop the microwave and stir the food after 3 minutes, then continue heating. After stirring, you can continue to reheat the food for less than 3 minutes more.
If you’re using vented Tupperware lids, don’t just shake the container to stir. Completely remove the lid and give the food a good stir to release steam and help with even cooking. In general, I consider microwave-safe glass and ceramic better for the microwave, because you can use a longer cook time.
How do you reheat food in Tupperware?
Here are some simple directions for reheating food in Tupperware:
Time needed: 2 minutes.
Microwave Food in Tupperware
- Make sure you use a microwave safe plastic container.
Either look up the product on the Tupperware website, or look for the microwave-safe symbol on the product.
- Add the food to be heated to the microwave-safe container.
If you’ll be using water or another liquid to help keep the food moist, add that now as well.
- Cover the container and vent (if desired).
If you’re using a microwave-safe lid to seal the container, make sure to leave the vent open. If using microwave-safe plastic wrap, leave a corner of the wrap open to allow steam to escape.
- Microwave, check, stir.
If I’m unsure how long to microwave the food, I like to start with a 30-60 second interval on medium power. Add time if necessary. Remember that you must stir the food after 2-3 minutes if using a microwave-safe Tupperware container.
Is Tupperware dishwasher safe?
Tupperware states that all of their current products are dishwasher safe unless otherwise noted (source). It’s a good idea to be extra cautious and look for the dishwasher safe symbol on the product. The symbol is often plate(s) or a wine glass with a water droplet, or being rinsed with water.
Tupperware products produced prior to 1980 are not dishwasher safe. (Makes sense, since many of us didn’t use dishwashers back then.)
Should I throw away my old Tupperware?
I’d consider discarding Tupperware plastic purchased before 2010 if you want a Bisphenol A (BPA) free kitchen. BPA is no longer in baby bottles, sippy cups, and formula packaging (Food and Drug Administration). I don’t think it’s a terrible idea for adults to reduce exposure from their food packaging as well.
To avoid any potential risks associated with microwaving in plastic, use microwave-safe glass and ceramic containers. When using a plastic container in the microwave, only use it to reheat foods for short periods. Do not cook food in the microwave in plastic containers.
Three types of containers that are microwave oven safe are microwave-safe glass, microwave-safe ceramic, and microwave-safe plastic containers. According to the USDA, wax paper, parchment paper, and paper towels are also microwave safe.
Don't use metal types of containers in the microwave; these can cause microwave damage, sparks, or fire. “Metal” includes stainless steel, copper, iron, and large pieces of aluminum foil. It's also important to not use plastic or glass in the microwave that is not listed as microwave-safe.
In general, microwave-safe Tupperware can handle higher temperatures than their plastic containers not safe for microwave. Tupperware recommends allowing hot foods and hot liquids containing fat to cool before putting them in the container. This includes items with cooking grease and hot oil.
Tupperware doesn’t currently sell porcelain plates on their website. Plastic plates in Tupperware’s Microwave Reheatable line are microwave safe. Items in Tupperware’s Big Wonder line should not be used in the microwave.
Some Tupperware is freezer safe, and other items (such as the TupperKids feeding set) should not be put in the freezer. Check the manufacturer instructions for your specific product for the most accurate information.
Is it safe to microwave plastic?
What are the dangers of using plastic containers like Tupperware to heat up food? Honestly, microwaving food in plastic is not ideal, but some plastics are worse than others.
In general, plastics with the recycling symbols 3 (phthalates), 6 (styrene), and 7 (may contain BPA) should be avoided for food storage entirely (source). (There are exceptions if the plastic is greenware or biobased.) These types of plastic may leach endocrine disruptors and/or potential carcinogens into the food.
A lot of the food sold in plastic containers in grocery stores comes in containers with the recycling code 1 (PET or polyethylene terephthalate) or 2 (HDPE or high-density polyethylene). In many cases, these are single-use containers that you shouldn’t microwaved. Additionally, #1 plastic has a low melting point.
Tupperware CrystalWave Plus containers are made with #5 plastic, AKA PP or polypropylene. This type of plastic is often microwave safe.
Low-Density Polyethylene (LDPE), or #4 plastic, is often in the lids of containers. It may or may not be safe for the microwave.
The FDA says it’s ok to use plastic containers labeled for microwave oven use in the microwave. This is mostly because these containers won’t melt in the microwave. If you have any concerns about the safety of microwaving in plastic, Tupperware carries microwave safe glass containers you can use instead.
