发明名称 SURFACE HEATING FOOD WRAP WITH VARIABLE MICROWAVE TRANSMISSION
摘要 The present invention provides a composite material for generation of heat by absorption of microwave energy comprising a porous dielectric substrate and a coating comprising a thermoplastic dielectric matrix and flakes of a micorwave susceptive material distributed within the matrix, said flakes having an aspect ratio of at least about 10, a generally planar, plate-like shape, with a thickness of about 0.1 to about 1.0 micrometers, a transverse dimension of about 1 to about 50 micrometers, and angular edges. The composite material exhibits decreased microwave transmission as a function of previously applied pressure.
