What is PVC film popular science aluminum foil?

PVC film popular science aluminum foil is a hot stamping material that is directly calendered 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 it will fade when rubbed or touched, so it is not suitable for hot stamping of the covers of books and periodicals that are stored for a long time.
