What are the physical properties of aluminum foil

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, tasteless, non-toxic, good fragrance retention, shading and heat insulation, good corrosion resistance;

2. Aluminum foil: a hot stamping material directly calendered into thin sheets with metal aluminum, and its hot stamping effect is similar to the effect of hot stamping of pure silver foil, so it is also known as fake silver foil. Due to the soft texture and good ductility of aluminum, it has a silvery-white luster, and if the calendered sheet is framed on offset paper with sodium silicate and other substances to make aluminum foil sheet, 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 and touched, so it is not suitable for hot stamping of long-term book covers.
