Ordinary plastics, especially colored plastic cups, will decompose into toxic substances in case of high temperature, which is harmful to human health. The only plastic cup that can be put into the microwave oven is PP, i.e. No. 5 polypropylene, which can withstand 200 ℃

It can be heated in a microwave oven, but don't put it in the oven. Of course, it would be better if there were a special microwave oven to heat utensils.

Before considering whether to put the plastic cup into the microwave oven, you can first look at the triangular logo and number at the bottom or side of the plastic water cup. If the number is 5, you can put it into the microwave oven for heating, and don't put others. It should also be noted that some microwave oven lunch boxes are indeed No. 5 PP, but the box cover is No. 1 PE. Because PE is not resistant to high temperature, it cannot be put into the microwave oven together with the box. To be on the safe side, remove the lid before putting the glass into the microwave oven.
