Zusammenfassung:A sheet material to be made into an object by an industrial forming process, the material comprising a metal substrate and a polymer coating system bonded thereto, the coating system comprising - an inner layer comprising PET, modified PET and/or combinations thereof, as a layer for bonding the system to the substrate; - a layer comprising PET, PBT and/or combinations thereof, as a barrier layer; - an outer layer comprising PET; wherein the outer layer has non- tacking properties so as to avoid sticking of the material to the forming tools at normal operation temperatures in the industrial forming process.
