ABSTRACT:
Paperboard packaging material for use in the manufacture of cartons for browning and crisping food in a microwave oven is prepared on a printing press using an aqueous susceptor-ink composition comprising graphite or conductive carbon black dispersed in a solution of sodium silicate. The susceptor-ink composition is printed on the packaging material in a pattern corresponding to the location of the food intended to be packaged and the food contact surface is overprinted with an FDA approved food contact coating. The use of sodium silicate as the binder for the susceptor-ink composition allows the composition to be printed by gravure or flexographic printing processes and provides hereto unavailable flame retardant properties to the final packaging material.
