Abstract
A package for heating, browning, and/or crisping a food item in a microwave oven, comprises a packaging material configured to define an interior space for receiving a food item, at least two portions of the packaging material being joined to one another to define a sealed area adapted to be situated above a lowermost portion of the food item received in the interior space, the sealed area being configured to weaken in response to thermal energy, and a microwave energy interactive material joined to a side of the packaging material facing the interior space, at least a portion of the microwave energy interactive material being disposed within the sealed area.

A package for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a packaging material configured to define an interior space for receiving a food item, at least two portions of the packaging material being joined to one another to define a sealed area adapted to be situated above a lowermost portion of the food item received in the interior space, the sealed area being configured to weaken in response to thermal energy;
- and
- a microwave energy interactive material joined to a side of the packaging material facing the interior space, at least a portion of the microwave energy interactive material being disposed within the sealed area.
A package for heating, browning, and/or crisping a food item in a microwave oven, comprising:
- a base configured to underlie a food item for heating in a microwave oven;
- an upper portion adapted to overlie the food item, the upper portion including a sealed area configured to weaken in response to thermal energy;
- and
- a susceptor disposed within the sealed area, the susceptor being operative for converting microwave energy into thermal energy for weakening the sealed area.
A method of preparing a food item in a microwave oven, comprising:
- providing a package for receiving the food item, the package including
- a base for underlying the food item,
- an upper portion for overlying the food item, the upper portion including a sealed area that weakens in response to thermal energy, and
- a susceptor disposed within the sealed area;
- exposing the food item in the package to microwave energy, whereby the susceptor converts at least a portion of the microwave energy to thermal energy, whereby the thermal energy weakens the seal and creates a venting opening.
