Abstract
A microwavable package includes a base to support a food product, an active microwave energy heating element is on the base to effect heating of the food product upon impingement by microwave energy. A cover spaced from and separate to the active microwave energy heating element overlies the food product. The cover includes microwave energy interactive material extending substantially over the food product and at least one layer of suscepting material interposed between the food product and the microwave energy interactive material. A plurality of apertures are formed in the microwave energy interactive material and are spaced apart about a peripheral margin of the cover. The apertures are sized to promote localized fields to enhance the at least one layer of suscepting material and promote browning of the food product when exposed to incident microwave energy.
