There will be some signs suitable for microwave ovens on the surface of the plastic bowl, such as the triangle "5" sign at the bottom, which means that the plastic bowl can be heated by microwave ovens. It should be noted that some plastic bowls, especially instant noodle bowls in fast food restaurants, contain harmful substances such as polystyrene (ps). After buying a special bowl for microwave oven, be sure to check whether there is a special sign for microwave oven at the bottom of the bowl, which cannot be used for microwave oven heating.
