Some Tupperware can be microwaved directly, and some cannot.

Tupperware with a heat-resistant temperature and microwave-safe markings on the bottom, lids with air holes, and cooking Tupperware designed specifically for microwave use can be used. Some Tupperware can be deformed when used with the lid on, so it’s best to check beforehand.

Points to Note When Microwaving Whole Tupperware

When using Tupperware to heat or defrost food, there are a few things to keep in mind.

  • Metal containers and the like cannot be used because they may spark. We recommend using microwave-safe plastic, heat-resistant glass, or magnetic products.
  • Tupperware without ventilation holes may cause the contents to be pressurized, and when the lid is opened, the contents may spurt out and cause burns, so open the lid lightly.
  • For thickened foods such as curry, the center of the food may be cold during heating, so it is best to stir the food during heating and then repeat the process in the microwave.

When you buy prepared foods or lunch boxes, you may wonder, “What is the maximum heating temperature for this? When you buy prepared foods or lunch boxes, you may be worried about the heating temperature. If you remember the marks, you can refer to them when you heat the food.

Polystyrene (PS)

Polystyrene (PS) has a heat resistance of around 70 to 90 degrees Celsius.

Polystyrene (PS) has a heat resistance of around 70 to 90 degrees Celsius and is useless in microwave ovens. Some Tupperware is safe to use in the microwave, so it is recommended to check.

Polypropylene (PP)

Polypropylene (PP) can be used in a microwave oven with a heat resistance of around 110-130 degrees Celsius.

However, foods with a lot of water, fried foods, or foods with a lot of oil may exceed the listed temperature when microwaved, so it’s best to consider the type of food before using it.

What is the Temperature Resistance of Tupperware That Can be Used in a Microwave Oven?

The heat resistance temperature of Tupperware that can be used in a microwave oven is around 120-140 degrees Celsius, and above 140 degrees Celsius is fine. There are some Tupperware that can be used in the microwave, but there are concerns about deformation. If you want to use the Tupperware for freezing, make sure it is microwavable. If you want to use Tupperware for freezing, it would be useful to check the cold resistance temperature as well.

When you heat a Tupperware in the microwave, you may find that the lid does not open! The reason is that the air pressure inside the Tupperware drops when it cools down after heating. To solve this problem, boil the Tupperware in hot water or reheat it in a microwave oven, and it will be easier to open the lid. You can also try inserting a thin object between the Tupperware and the lid to create a gap between the Tupperware and the lid.
