Aluminum foil board, full name aluminum foil composite board, is a functional plate made of aluminum foil (pure aluminum or aluminum alloy foil) and core material through bonding, hot pressing and other processes. It combines the moisture-proof, thermal insulation and antibacterial characteristics of aluminum foil, as well as the support and load-bearing capacity of the core material, and is widely used in many fields such as architectural decoration, furniture cabinets, and cold chain packaging.
