Most disposable tableware is best left unheated, whether or not it will melt. Some disposable lunch boxes can be heated.

The material of disposable lunch boxes is polystyrene, which is easy to melt in high temperature environment. Corrosion by strong acid and alkali, not resistant to grease, easy to change color after being irradiated by ultraviolet rays.
The safety of foamed plastic tableware is related to the pH of the food, whether it contains oil, temperature, etc. The state stipulates that the foam plastic lunch box should be used below 70 ℃, so it is best to use only microwave-specific heating appliances for microwave heating for safety reasons.
