The main material of the disposable foam lunch box is polystyrene, which is not resistant to high temperature and easy to absorb oil.
Generally, heating in a microwave oven for a short time will not precipitate excess plasticizer. However, if the temperature exceeds the upper limit of heat resistance, the plasticizer may also be released, and long-term heating of plastic lunch boxes with high temperature should be avoided.
