Hello! I'm glad to answer it for you. Under normal use, the temperature is lower than 120 degrees Celsius, which is non-toxic and safe. Many inferior disposable lunch boxes have seriously exceeded the standard. As soon as the microwave oven is turned on, harmful substances will dissolve in food (as will hot water bubbles). These lunch boxes are filled with a lot of waste plastics and fillers, which will be released when heated or drained. Among them, industrial calcium carbonate is easy to form gallstones and kidney calculi, which is also very harmful to human digestive tract and nervous system. If heated by microwave oven, raw materials or additives may be decomposed and melted due to ultra-high temperature, releasing elements that affect human health. Long-term intake will lead to indigestion, gallstones and liver system diseases. If the material contains industrial paraffin, it may even cause cancer.
So it's safer to pour out the food and put it in the microwave with your own bowl, and it's safer to eat. I hope it helps you.
