Abstract: A method for the coating of a chromium-free surface of a tin-plated steel sheet with a polymer coating, with the chromium-free tin surface of the tin-plated steel sheet first electrochemically oxidized in a first step and a polymer coating applied on the oxidized tin surface in a second step, and an apparatus for the carrying out of the method. A tinplate coated with a polymer coating made of polyethylene terephathalate (PET) and passivated chromium-free, wherein only one thin tin oxide layer and perhaps an adhesion promoter layer are present between the tin surface of the tinplate and the polymer coating, and the use of such a tinplate for the production of packagings.
