Aluminum foil (also known as tin foil in North America and Australia) is aluminium prepared into very thin metal leaves with a thickness less than 0.2 mm. It has many uses, including lining thermal bags and other products, protecting foods, and preventing moisture and light from damaging their contents.

It is lightweight, safe for use around food and skin, malleable, and corrosion-resistance. It is also easily recycled.

Is Aluminium Foil Flammable?

As with most materials, aluminum foil is not flammable. However, if you were to heat it to the point where it started to burn, a chemical reaction would occur and a substance called aluminum oxide would be formed.

This oxide film, which is only a micrometer thick, protects the aluminum from a reaction with water. When this layer is destroyed, a chemical reaction will take place which produces a very flammable hydrogen gas.

Does Aluminum Foil Leach in the Oven?

When foil is in contact with food it can absorb a small amount of acidic chemicals and other components from the food. It does this even more when the temperature is high.

Will Saran Wrap Melt if Lined with Aluminum Foil?

When aluminum foil is placed in the oven, it acts as a barrier between hot air and the Saran wrap, protecting the Saran wrap from melting. Using an extra layer of aluminum foil will allow the Saran wrap to keep its 220 deg F melting point without melting the aluminum foil.
