VCI (Volatile Corrosion Inhibitor) is a type of technology that provides protection against corrosion in metal objects during storage and transport. VCI technology is used in various forms such as VCI paper, VCI film, and VCI foam. These materials are designed to emit vapor that protects metal surfaces from corrosion by creating a barrier between metal surfaces and the environment. VCI paper and VCI film are two of the most commonly used forms of VCI technology for protecting metal surfaces. The choice between these two options often depends on the specific requirements of the application and the type of metal that needs to be protected
