Microwave heating requires containers such as glass, ceramics and high-temperature resistant plastics, mainly because the chemicals in glass are relatively stable and can be heated by microwave oven. Ceramic ware itself is forged at high temperature, so it can also be heated by microwave oven. In addition, high-temperature resistant plastic products, such as polypropylene, polypropylene resin and composite polypropylene, can also be used.

Items that cannot be heated by microwave oven:

1, common plastic container: heating food will deform the plastic container. Secondly, ordinary plastics will release toxic substances after heating, which will pollute food and endanger human health.

2. Metal utensils: If iron, aluminum, stainless steel, enamel and other utensils are put into a microwave oven for heating, the microwave oven will generate electric sparks with them, which will reflect microwaves when heating, which will not only damage the furnace body, but also heat immature food.

3. Closed container: wide-mouth container should be used when heating liquid, because the heat generated by food heating in closed container is not easy to dissipate, so that the pressure in the container is too high and it is easy to cause explosion accidents.

4. Bottled baby food or the original bottle with a half-full lid: You can't put it in the furnace to heat it, otherwise it will easily cause the bottle to break.

5. Paper products and wood products: These substances can easily burn containers and even endanger microwave ovens when exposed to high temperatures. However, when encountering high temperature, the inside of the closed liner is easy to expand and cannot be distributed. To a certain extent, the air in the container is insufficient and an explosion may occur.

6, non-food plastic bags, unmarked plastic wrap for microwave ovens: can not be directly heated with food, otherwise it will release toxic substances after melting.
