Abstract
A present invention provides a microwave interactive laminate and a process for brush deactivation of such a laminate. A film, coated with a microwave interactive layer is provided. A desired portion of the microwave interactive layer is coated with a mask layer and the entire assembly is then exposed to abrasion means. The coated and un-coated areas are subjected to the application of mechanical forces to form discontinuities in the microwave interactive layer. That portion of the microwave interactive layer that was coated remains interactive with microwave radiation and is a heating area while the un-coated area is deactivated.
