Aluminum foil paper for food can be used to wrap food on both sides. It is usually recommended to wrap food on the glossy side to improve the heat conduction effect. Because aluminum has a soft texture, good ductility, and a silvery white luster, if the calendered sheet is mounted on offset paper with sodium silicate and other substances to make aluminum foil, it can also be printed.
Aluminum foil has a clean, hygienic and shiny appearance. It can be made into integrated packaging materials with many other packaging materials, and the printing effect on the surface of aluminum foil is better than that of other materials.
