Abstract
A process for treating food and beverage containers comprised of low-carbon steel sheet (black plate) to improve the adherence and to resist undercutting of organic can lacquers applied to the surfaces thereof when subjected to agressive environments without visually impairing the light-grey shiny steel appearance of the container surface and without loss of humidity resistance. The treatment can readily be integrated with conventional can body manufacturing procedures and includes contacting the cleaned black plate container body surface with an aqueous acidic solution containing a controlled amount of stannous ions at a controlled temperature for a period of time sufficient to deposit tin on the surfaces thereof in an amount up to about 5 mg/ft.sup.2 followed by rinsing, drying and lacquering.
