What material is aluminium foil made from?

[tom]

Aluminum foil is a hot stamping material that can be directly rolled into aluminum sheets. Its hot stamping effect is similar to that of pure silver foil, so it is also called fake silver foil. Because of its soft texture, good ductility and silver-white luster, aluminum foil can also be printed if the calendered sheet is mounted on offset paper with sodium silicate and other materials. However, aluminum foil itself is easy to oxidize, color darkening, friction, touch, etc. will fade, so it is not suitable for long-term preservation of books and periodical covers, such as hot stamping.
