Since these cups consist of ordinary plastic, that is not suitable for high-temperature applications like microwave or oven and can cause significant damage. If you heat your food in these cups, it can be wasted and create a mess. 

Even if it does not melt, the cup can become extremely hot when you try to microwave it, which can burn your hands if you try to hold the cup immediately after the microwave stops.
