Abstract:

Paperboard packaging material for use in the manufacture of containers or inserts for containers for browning and crisping food in a microwave oven is prepared on a printing press. The components of the packaging material include paperboard or an equivalent microwave transparent substrate, a susceptor layer prepared from a printable aqueous susceptor-ink composition, and an intermediate coating applied to the paperboard substrate between the susceptor layer and the paperboard to provide a thermal barrier for the paperboard substrate. The thermal barrier layer may be coated or printed on the paperboard substrate as a substantially uniformly thick layer while the susceptor-ink layer may be pattern-printed on the substrate in varying thickness corresponding to the location of food intended to be packaged in containers prepared from the packaging material. The printed susceptor material is overprinted with a food contact coating. The invention also contemplates the use of pigments or the like in one or more of the food contact layer, susceptor layer or thermal barrier layer to facilitate the release of water vapor from these layers during the microwave heating process.
