Danger:
First, the heated food will deform the disposable lunch box and make it impossible to heat the food.
Second, disposable lunch boxes will release toxic substances such as benzopyrene during heating, which will not only pollute food, but also endanger human health.
Other appliances that cannot be heated by microwave oven:
A, metal appliances
As iron, aluminum, stainless steel, enamel and other utensils are put into the furnace, electric sparks will be generated when the microwave oven is heated, which will not only damage the furnace body, but also heat the food.
Second, close the container.
Wide-mouth containers should be used when heating liquid, because the heat generated by heating food in a closed container is not easy to dissipate, which makes the pressure in the container too high and easily leads to blasting accidents.
3. All heat-resistant containers, such as bamboo and lacquerware, and concave-convex glass products are not suitable for use in microwave ovens.
Fourth, porcelain plates can't be inlaid with honeysuckle.
