Unveiling the Truth: Can Tupperware Safely Go in the Microwave?

Introduction   Tupperware has been manufacturing its iconic plastic food storage containers for almost seventy



Tupperware has been manufacturing its iconic plastic food storage containers for almost seventy years. When it comes to Tupperware, one of the most often asked concerns is whether or not it can be used properly in a microwave. Using Tupperware in the microwave has been called dangerous by some, while others insist it’s completely safe. We hope that at the end of this essay, you will have enough information to make an educated choice regarding whether or not to use Tupperware in your own microwave.

Understanding Tupperware


Let’s examine what Tupperware is and how it functions before delving into the controversy surrounding its use in microwave ovens. Tupperware is constructed from polyethylene, a kind of plastic renowned for its strength, malleability, and resilience to moisture and heat. Tupperware’s hermetic seal means food stays fresh for far longer than it would otherwise.

The Microwave Factor


Microwave ovens generate heat by quickly vibrating water molecules in food using electromagnetic radiation. Some materials absorb microwave radiation more readily than others, and this absorption rate varies depending on the material. This explains why certain foods need more time in the microwave than others to reach the desired temperature.

Tupperware has been criticised because of fears that heating the plastic might unleash dangerous chemicals. Research has shown that microwaving food in plastic containers might release harmful chemicals like bisphenol A (BPA) into the meal.

Tupperware and Microwave Safety

If you’re worried about using your Tupperware in the microwave, the business offers instructions on how to do it securely. As long as the Tupperware is not entirely sealed and contains food or drink, it may be heated in the microwave without risk. By doing so, pressure within the container is relieved and the possibility of a catastrophic rupture is reduced.

While many microwave-safe plastic containers are safe to use in the microwave, some experts advise against it. They claim that exposing food to high temperatures triggers plastic to degrade and produce toxic compounds.

Real-Life Testing

Whether or whether Tupperware may be safely heated in a microwave has been the subject of several scientific investigations. When food is cooked in plastic containers like Tupperware, the amount of bisphenol A (BPA) in the food increases dramatically, according to a research published in the Journal of Environmental Health Perspectives. But the concentrations were still well below the regulatory threshold for safety.

Microwaving plastic containers has not been shown in other research to significantly enhance chemical leaching. Microwave-safe plastic containers, for instance, did not emit any dangerous compounds when cooked in a microwave, according to a research published in Food Additives & Contaminants: Part A.

Alternatives to Tupperware

There are various microwave-safe containers on the market if you’re worried about using Tupperware in the microwave. Glass is often used in place of plastic since it does not break down into toxic compounds when heated. The microwave is safe for use with stainless steel containers, albeit they may not be the best choice for reheating certain foods.

Tips for Safe Microwave Use

If you’re going to use Tupperware or any other microwave-safe container, there are a few precautions you should take. Here are some things you should and should not do:


  • Containers suitable for use in microwaves
  • Allow some steam to escape by leaving the lid slightly ajar.
  • To achieve equal heating, use low settings and stir or rotate food periodically.


  • Put food in non-microwave-safe containers in the microwave.
  • Sealing containers too tightly might cause them to break.
  • Plastic wrap may melt and leach toxins into food when heated.
  • Put things in damaged, discoloured, or deformed containers.


The use of Tupperware in the microwave has been met with some criticism, although following the manufacturer’s instructions seems to be safe for the vast majority of consumers. You may use glass or stainless steel containers instead of plastic ones in the microwave if you’re worried about food safety. It is possible to safely reheat leftovers in a microwave by adhering to a few simple rules.
