Abstract (en)
A microwavable package (48) may include one or more microwave-absorbing regions (62), 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 (62) (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 (20) may be a conductive grid or a grid of conductive or non-conductive shapes (e.g., squares, triangles, circles). In an embodiment, solid susceptors (62) and patterned susceptors (20) 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.
The package has solid susceptors (62) and patterned susceptors that are formed from a common thin metal film on a common polymer barrier layer and laminated to a common structural backing layer. The patterned susceptors are a conductive grid/grid of conductive or nonconductive shapes e.g. squares, triangles, circles. A base allows air to circulate between food product and an interior surface of the package. An independent claim is also included for a method of packaging a food product to be cooked with microwave energy.
