A microwave laminate for heating, browning, and crisping food products is provided. The microwave-absorbing region of the laminate is formed from electrically conducting film of shielding thickness. The film is patterned to provide an increased effective electrical sheet resistance that allows the susceptor to substantially absorb rather than reflect microwave energy. Also, a microwave susceptor underlay or shield formed from a patterned electrically conducting film of shielding thickness is provided for controlling temperature gradients within microwave susceptors.

1. A microwaveable laminate comprising:a first layer substantially transparent to microwave energy, the first layer having an electrically insulating first surface; and a second layer having at least one microwave-absorbing region of patterned electrically conducting film, wherein the at least one microwave-absorbing region comprises conductive portions and nonconductive portions, wherein a section of conductive portion between nonconductive portions is configured to break to inhibit arcing and damage to other regions of the patterned electrically conducting film if the section is exposed to excessive heat during use, wherein the conductive portions have a thickness corresponding to a surface resistivity greater that about 0.5 ohms per square of material (.OMEGA./□) and a surface resistivity less than 10.OMEGA./□, and wherein the patterned electrically conducting film provides an effective electrical sheet resistance that is greater than about 20.OMEGA./□ and less than about 500 .OMEGA./□.
