Blue coated aluminum foil

Blue coated aluminum foil is a kind of stamping material which is directly calendered into thin sheet by metal aluminum. Its stamping effect is similar to that of pure silver foil, so it is also called false silver foil. Because of the soft and malleability of aluminum, it has silver white luster. If the calendered sheet is mounted on the offset paper with sodium silicate and other materials, the aluminum foil can also be printed. But aluminum foil itself is easy to oxidize and its color becomes dark, friction, touch and so on will fade. Therefore, it is not suitable for the long-term preservation of the book and magazine cover and other hot stamping.
