You can carefully observe the front and back of the tin foil, which is actually different. One side is bright and the other side is dark. The dark side is a frosted surface, which is in contact with food. The bright side is the photosensitive surface, which is in contact with the heat source. The functions of both sides are also different. The smooth side can better absorb external heat, thus helping food to be heated evenly. After touching the food, the matte surface touches the food.

Do you use tin foil for baking sweet potatoes in the microwave oven? You can't put tin foil in the microwave.
Tin belongs to metal, so the packaging, boxes and containers of metal products can't be heated in the microwave oven, because the microwave can't penetrate the metal, so the food won't be heated. Secondly, the metal will reflect the microwave and damage the microwave tube. In the light, it will produce an electric spark, and in the heavy case, it will catch fire and explode.
Therefore, tin foil paper is used to bake and heat food in the oven. If heated in a microwave oven, the metal packaging must be removed. For example, sweet potatoes are baked in a microwave oven. In order to avoid drying, sweet potatoes can be wrapped in wet tissues and baked, and the taste is also very good.
