ABSTRACT:
A flexible sheet structure is described which comprises a base sheet having a microwave coupling layer, e.g. electrodeposited aluminum as an island covering a selected area of the sheet. The uncoated portions will not be heated and will not be damaged by microwave energy. The selectively located microwave coupling covered area transfers absorbed heat to a product by thermal conduction. In one form of the invention a flexible fibrous backing sheet such as paper is bonded to the base sheet to provide dimensional stability and prevent warping, shriveling, melting or other damage during microwave heating.
