ABSTRACT:
A patterned microwave interactive element and laminate including a patterned microwave interactive element for use in forming food packaging materials that may be employed to store and subsequently cook the food stored therein are provided. The pattern of the microwave interactive element is selected to focus the heat generated to predetermined areas of the food contained in the packaging. Areas where the microwave interactive element has been deactivated may be formed by a variety of methods, such as by demetallization, by the application of an inactivating chemical, by mechanical means and the like, to create a preselected pattern of inactive areas relative to the active areas, thereby controlling the temperatures produced in different sections of the packaging material. Optimum browning and/or crisping of the microwave heated food product may be achieved by selecting a pattern of microwave interactive and inactive areas tailored to specific food products.
