ABSTRACT:
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.
