Aluminum foil is a hot stamping material that is directly rolled into thin sheets with metal aluminum. Its hot stamping effect is similar to that of pure silver foil, so it is also called fake silver foil.
Because aluminum has a soft texture, good ductility, and silver-white luster, if the rolled sheet is mounted on offset paper with sodium silicate and other materials to make aluminum foil, it can also be printed. However, the aluminum foil itself is easy to oxidize and the color becomes dark, and the color will fade when rubbed or touched, so it is not suitable for hot stamping of the covers of books and periodicals that have been stored for a long time.
Aluminum foil has a wide range of applications in packaging, electrolytic capacitors, heat insulation, etc. It is characterized by soft texture, good ductility, and silver luster.
