ABSTRACT:
Barrier coatings are disclosed to reduce the migration of contaminants from paperboard into food products packaged in containers prepared from the paperboard. The barrier coatings operate to either absorb the contaminants or provide a tortuous path to their migration from the paperboard particularly at the high temperatures reached during the cooking of the food products in microwave ovens.
