MICROWAVE INTERACTIVE LAMINATE AND PROCESS FOR PRODUCING MICROWAVEINTERACTIVE LAMINATE

摘要

The present specification discloses a process for chemically treating the microwave interactive layer of a microwave interactive laminate to reduce or eliminate the capacity of the microwave interactive layer to generate heat in response to microwave energy. The present invention also relates to chemically modified microwave interactive film and chemically modified microwave interactive laminates which include a chemically treated microwave interactive layer. Thus there is provided a microwave cooking heater element comprising a heat stable plastic film coated with a very thin metallic layer to form a microwave interactive film, wherein the very thin metallic layer includes an inactivated area wherein the capability of said inactivated area to generate heat in response to microwave energy has been reduced by treatment with an inactivating chemical followed by drying.
