Can vacuum packaged food be heated in the microwave oven??

microwave has high energy, which makes the electrons in metal materials extremely active. When it reaches a certain level, it will discharge. By blackening, you mean that the tin foil is discharged and shocked to the microwave oven to burn black (because the discharge produces high temperature)
and the tin foil is insulated. You put a glass of water and an ice wrapped in tin foil in the microwave oven. Finally, the water boils, but the ice hardly melts. Let’s say: metal and enamel products cannot be used in microwave cooking utensils, because metal reflects microwaves. It not only leads to the reduction of heating efficiency and poor heating uniformity of microwave oven, but also makes the microwave contact with metal to produce sparks, which is dangerous. In serious cases, it will also damage the magnetron
however, some special effects can also be achieved by using the properties of reflected microwaves such as metals. Tin foil (aluminum foil) is also a kind of metal material, which can also reflect microwaves. If we cook food that takes a long time, we can use a small amount of “tin foil” to wrap the easy cooked food. After cooking for a while, remove the “tin foil” and continue cooking, which can make the food cooked more evenly. However, when using, the smooth part should be close to the food to reduce the reflected energy.

Yes, because it is vacuum

Yes
