1. Plastic lunch box with poor heat resistance
Ordinary plastic lunch boxes have poor heat resistance and cannot be used as microwave cooking utensils.
2. Glass lunch box with poor heat resistance
When food is cooked with oil, the temperature may be very high, which can easily break the glass lunch box. Therefore, glass lunch boxes that are not heat-resistant cannot be used.
3. Metal lunch boxes that cannot be penetrated by microwaves
Metal lunch boxes such as aluminum pots, enamel pots and stainless steel pots cannot be penetrated by microwaves, and the inner wall of the furnace will ignite when they touch metal, so they cannot be used.
4. Lacquer lunch box

The lacquer on the lacquerware lunch box may peel off and melt after being heated, producing harmful substances. The container may also crack, and eating heated food is not good for your health.
