The structure of passivization film has an important role in the adhesion of lacquer on the tinplate, and also in further behavior of the can filled with a different content. It is for this reason that the composition of passivization film and its influence on lacquering and adhesion were examined in this work. The composition of passivization film on the tinplate was examined after storage by the application of the AUGER spectroscopy (AES) and by the X-ray photoelectric spectroscopy (ESCA). The results show that the tinplates stored during three years have surface composition and capability of adhesion acceptable for use in food industry.
