Is Tupperware Microwave Safe?
Not all Tupperware is microwave safe. The ones that are microwave-safe should be used according to the given guideline in order to prevent any kind of damage. The reason is that they are constructed from the safest type of plastic called polyethylene terephthalate which is lightweight, strong, shatter-resistant, and can withstand high temperatures. Furthermore, this plastic Tupperware is approved for storing food by the FDA.
Following are the basic guidelines that one should follow when using Tupperware in your microwave.
- Use that specific Tupperware that has a microwave-safe label.
- Do not directly contact your Tupperware with the heating element of your microwave.
- Make sure to follow the reheating instructions that are listed on their containers.
- Avoid using Tupperware with decoration or any other metal trim in the microwave.
- After heating, make sure to cool down the food in the Tupperware container and then eat.
Furthermore, it is very important to keep in mind that only Tupperware can be used in a microwave safely that is labeled with a “Microwave-safe” label at the bottom. As not all of them are created equally with premium quality plastic, they can also induce various harmful chemicals while heating the food. Secondly, avoid Tupperware that is scratched or old as they are likely to release certain harmful chemicals.
Moreover, make sure not to heat the food in the Tupperware for a longer time period as overheating is also one of the major causes of releasing chemicals in the food. Apart from this, other containers made from metals or other types of plastic can cause sparkling or many other problems while heating the food in the microwave. Your basic storage containers are also not meant to be microwave safe and should be avoided.
Plastic Vs Glass Tupperware
As the market is filled with both glass as well as plastic Tupperware, both are considered to be durable and safe for storing food. However, the glass Tupperware is exposed to thermal shocks. Thermal shock is basically the shattering of the glass surface by the extreme temperature change, causing stress. This phenomenon is most common with frozen glass containers. Apart from being microwave safe, the Tupperware should also be freezer safe in order to prevent any breakage or cracks.
While talking about plastic Tupperware, they are equally durable, convenient, and lightweight. However, many people resist using plastic Tupperware in the microwave even if they are rated to be safe. Furthermore, Tupperware constructed from premium quality plastic material is capable of withstanding extreme temperature changes i-e from scorching heat to freezing cold. Therefore, like glass containers, you should also follow the same heating guideline and indications for plastic Tupperware containers as well.
