The main components of tin foil: aluminum content is 96.9 1%, and other components are oxygen, silicon, iron, copper, etc. It has only a thin layer, usually less than 0.2 mm in thickness, but it has strong thermal conductivity and high temperature resistance.

Wrapping food with it can not only heat quickly, prevent burning, heat evenly, lock soup easily, keep fresh and tender taste, but also avoid oil stains on the oven. The heating time is generally less than 20 minutes, which will easily lead to the appearance and taste of food, because the baked food will release more water vapor, and the taste will change if it is heated in tin foil for a long time.
