Is tin foil harmful to health?

Many tin foil papers sold in the market now are aluminum foil papers. Both sides of the paper are plastic or special paint, and the middle layer is aluminum. It is ok if it is only used as packaged food, but if the food is directly packaged and baked, the harm to human body is direct. After food is fried, barbecued and smoked, it is easy to produce carcinogens such as phenylpropyl pyrene and dioxin, so it is really inappropriate to eat more.
