1. A method of uniformly distributing the heat generated by microwave interaction with a thin, flexible and non-self-supporting metallized film carried adjacent and co-extending over a substantial area of an inner wall of a disposable container for food to be exposed to microwave energy, as in an oven, that comprises, adhering the periphery of said metallized film to said wall peripherally to mount the film with substantially its major intermediate area loosely and flexibly spaced from said wall to define an air pocket between the film and said wall, and exposing the container with food therein to microwave-interacting heat generated along the metallized film, as it flexes in response to such convection, more uniformly to heat, crisp and/or brown the food in the container.
