Aluminum foil can't be microwaved

Aluminum foil can't be microwaved. Although it is as soft as paper, it is still essentially metal. Microwaves can't penetrate metal, so food won't heat up. In addition, the metal will also reflect the microwave, damage the microwave tube, generate electrical sparks, and even lead to fire, explosion. The oven is heated by the heat radiation of the heating tube, which belongs to the traditional heating method and is suitable for the use of aluminum foil. Aluminum foil can also be used in a microwave oven with barbecue function, but the premise must be barbecue mode, and must not be heated with microwave.

When using aluminum foil, many people still have a question: should you use matte or light bread food? In the production process, because the aluminum foil is very thin, in order to prevent breaking, manufacturers generally use two layers at the same time. Two layers of aluminum foil in the process of contact with each other, there will be friction, so the formation of dumb surface; And the other side directly in contact with the smooth machine, will form a smooth surface. There is not much difference in the time of heating food on both sides, and the reflectivity of the matte surface is 80% and that of the smooth surface is 88%, both of which can be used. However, it is recommended to use a matte surface in direct contact with the food, because the smooth surface is more likely to stick to the food.
