Coated aluminum coil and sheet are more resistant to keep food fresh. Coated aluminum coil and sheet improves anticorrosive properties of aluminum, which are commonly used in food packaging, containers and cans. In addition, the application of coated aluminum coil and sheet embraces large industries including composite panel, ceiling, door, windows and electric appliances.
