Abstract
An improved technique for uniformly distributing crisping or browning heat supplementation in disposable paper food carton or containers and the like used for microwave cooking, in which a metallized susceptor film is employed mounted to but intermediately spaced from the adjacent inner wall of the container to define and seal an air pocket which, in heating, improves the uniformity of the browning result through convection into air pocket and responsive flexing of the film.
