Microwave absorbing composite comprising at least two zones of material capable of absorbing microwave energy, each set of said two zones being separated by one zone of material transparent to or transmissive of microwave energy. The microwave energy absorbing zones are selected such that the composite is incapable of arcing in a microwave oven whereof the maximum power output does not exceed 2000 watts at a frequency of 2.45 GHz. The composite of this invention can be used for such purposes as crisping, browning, or otherwise heating food products, as a material for packaging, or as a package venting material.

A microwave absorbing composite comprising at least two zones of material capable of absorbing microwave energy, said microwave energy absorbing zones consisting of one or more layers of electrically conductive material, each pair of said microwave energy absorbing zones being separated by a zone of material transparent to microwave energy, said microwave transparent zone consisting of one or more layers of electrically insulative material, and at least one layer of adhesive capable of bonding said composite to a substrate, said adhesive having sufficient mechanical strength to overcome any distortion forces so that said composite does not curl or slip relative to the substrate to which it is adhered as the composite heats in response to microwave energy, provided that said composite is incapable of arcing in a microwave oven whereof the maximum power output does not exceed 2000 watts of a frequency of 2.45 HHz.
