Microwaving food in plastic containers has become a common practice in many households. However, the safety of this practice has been a topic of debate for years. One of the most popular brands of plastic containers is Tupperware, which has been around for decades. But the question remains: how long can you microwave plastic Tupperware?
Understanding the Risks of Microwaving Plastic Containers
Before we dive into the specifics of microwaving Tupperware, it’s essential to understand the risks associated with microwaving plastic containers in general. When plastic is heated in the microwave, it can release chemicals into the food, which can be harmful to human health. These chemicals, known as endocrine disruptors, can mimic the effects of hormones in the body and have been linked to various health problems, including cancer and reproductive issues.
The Dangers of BPA and Phthalates
Two of the most common chemicals found in plastic containers are Bisphenol A (BPA) and phthalates. BPA is a known endocrine disruptor that can leach into food when plastic containers are heated. Phthalates, on the other hand, are used to make plastics more flexible and have been linked to reproductive problems.
What Does the FDA Say?
The FDA has set limits on the amount of BPA and phthalates that can be used in food packaging. However, these limits are not always enforced, and many plastic containers still contain high levels of these chemicals. In 2012, the FDA banned the use of BPA in baby bottles and sippy cups, but it is still allowed in other types of food packaging.
Tupperware: A Safe Alternative?
So, is Tupperware a safe alternative to other plastic containers? The answer is not a simple yes or no. Tupperware is made from a type of plastic called polyethylene, which is generally considered to be safer than other types of plastic. However, Tupperware containers can still leach chemicals into food when heated.
Tupperware’s Microwave-Safe Claims
Tupperware claims that its containers are microwave-safe, but this claim is not without controversy. While Tupperware containers may not melt or warp when heated in the microwave, they can still release chemicals into food.
What Does the Science Say?
Several studies have investigated the safety of microwaving Tupperware containers. One study published in the Journal of Food Science found that Tupperware containers released high levels of BPA and phthalates when heated in the microwave. Another study published in the Journal of Agricultural and Food Chemistry found that Tupperware containers released chemicals into food, even when heated at low temperatures.
How Long Can You Microwave Tupperware?
So, how long can you microwave Tupperware? The answer depends on several factors, including the type of Tupperware container, the temperature of the microwave, and the type of food being heated.
General Guidelines

Is all Tupperware safe for the microwave?
Not all Tupperware products are safe for microwave use. Some older Tupperware products may contain chemicals like bisphenol A (BPA) or phthalates, which can leach into food when heated in the microwave. However, Tupperware has been BPA-free since 2010, and many of their products are now microwave-safe.
To ensure safety, always check the Tupperware product for a microwave-safe symbol or consult the manufacturer’s instructions. If you’re still unsure, it’s best to err on the side of caution and avoid microwaving the product.
What happens if I microwave Tupperware that’s not safe?
Microwaving Tupperware that’s not safe can cause the chemicals in the plastic to leach into your food. This can lead to the ingestion of harmful chemicals, which have been linked to various health problems, including cancer and reproductive issues. Additionally, microwaving non-safe Tupperware can also cause the plastic to warp, melt, or even catch fire.
To avoid these risks, it’s essential to only microwave Tupperware products that are specifically designed for microwave use. Always follow the manufacturer’s instructions and take necessary precautions to ensure safe microwaving.
How can I tell if my Tupperware is microwave-safe?
To determine if your Tupperware is microwave-safe, look for a microwave-safe symbol on the product. This symbol is usually a picture of a microwave with a dish inside. You can also check the manufacturer’s instructions or the Tupperware website for specific guidance on microwaving their products.
If you’re still unsure, it’s best to contact Tupperware’s customer service directly for advice. They can provide you with more information on the specific product you’re using and advise on safe microwaving practices.
Can I microwave Tupperware with metal trim or decorations?
No, you should not microwave Tupperware with metal trim or decorations. Metal can cause sparks or even start a fire when heated in the microwave. This is because metal reacts to the microwave energy and can cause arcing or sparks.
To avoid this risk, always check your Tupperware for metal trim or decorations before microwaving. If the product has metal parts, it’s best to avoid microwaving it altogether. Instead, use a different microwave-safe container to heat your food.
How long can I safely microwave Tupperware?
The safe microwaving time for Tupperware depends on the specific product and the type of food being heated.
