1. Physical properties of aluminum foil: thin and light, high specific strength, excellent silver-white luster, high thermal conductivity and electrical conductivity, high moisture resistance, odorless, non-toxic, good fragrance retention, shading and heat insulation, good corrosion resistance;
2. 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. Due to the soft texture of aluminum, good ductility and silvery white luster, if the rolled sheet is mounted on offset paper with sodium silicate and other substances to make aluminum foil, it can also be printed. However, the aluminum foil itself is easily oxidized and the color becomes dark, and the color will be faded by friction and touch, so it is not suitable for hot stamping of long-term preservation of book covers, etc.
