Is There Any Harm In Aluminum Foil Gasket After Heating?

It is not toxic to heat the aluminum foil gasket, because the aluminum foil gasket is a hot stamping material that is directly rolled into thin sheets with metal aluminum, and 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.
