aluminum foil in microwave
Our main products aluminum foil in microwave，led aluminum profile,etc.
The walls inside the microwave oven are actually made of metal. A fairly thick piece of metal is like a mirror, it can reflect microwaves. If you put the food in a metal pan and put it in the microwave, the food will not be heated. Metal pans can protect food from microwaves, so the food will never be heated.
But small and thin metal sheets are another matter. The electric field in the microwave causes current to flow through the metal. The walls of the microwave oven can usually withstand these currents without any problems. However, metal sheets such as thin aluminum foil are submerged by these currents and heat up rapidly. That's how the fire started. In addition, if the tin foil wrinkles to form sharp edges, the current flowing through the tin foil will produce sparks.
