Package for microwave cooking
First Claim
1. A microwavable package for cooking a food product using microwave energy, comprising:
- a lid member;
a base member;
wherein the lid member and the base member are configured to form a seal during use;
wherein an interior surface of the microwavable package comprises a patterned susceptor configured to control heat transfer and to shield the food product from incident microwave energy; and
wherein the microwavable package comprises paperboard.

Abstract
A microwavable package may include one or more microwave-absorbing regions, microwave-shielding regions, and/or embossed regions designed to enhance microwave cooking of food products including raw meat, poultry, and fish as well as breaded, battered, and dough containing items. Microwave-absorbing regions (i.e., solid susceptors) may promote thermal cooking, browning, and/or crisping of food products. Microwave-shielding regions (i.e., patterned susceptors) may promote uniform cooking and inhibit overcooking of food products. A patterned susceptor may be a conductive grid or a grid of conductive or non-conductive shapes (e.g., squares, triangles, circles). In an embodiment, solid susceptors and patterned susceptors may be formed from a common thin metal film on a common polymer barrier layer and laminated to a common structural backing layer. An embossed region of a microwavable package may promote crisping of a food product by allowing air to circulate between the food product and an interior surface of the microwavable package.
