An improved cooking bag in which, for instance, food can be uniformly cooked by microwave energy in a microwave oven without having to adjust the level of power or stir or reposition the food as is now commonly practiced due to microwave energy being unevenly distributed in contemporary microwave cooking apparatus. The improved bag is of the type having microwave energy moderating wall portions which comprise arrays of complemental-shape microwave reflective areas of electrically conductive material such as aluminum foil, and substantially microwave transparent areas. The bag is improved by having relatively low density, high bulk electrically insulative material disposed adjacent electrically conductive areas to sufficiently electrically insulate or space them to substantially obviate electrical arcing which arcing can, under some circumstances, occur intermediate such areas, and intermediate such areas and adjacent electrically conductive materials: for instance, metal components of a microwave oven and/or metal components or portions of other such bags or other cookware.

In an improved microwave energy cooking bag having microwave energy moderating wall portions which wall portions include electrically conductive sheet material which is substantially fully perforated with a multiplicity of apertures of predetermined sizes with respect to a predetermined nominal frequency of microwave energy and which sheet material has some face-to-face areas, and which bag includes means for substantially obviating electrical arcing intermediate adjacent said face-to-face areas of said electrically conductive sheet material, the improvement wherein said means comprises a relatively thick, relatively low density batt of a relatively low dielectric loss factor, relative high electric field strength electrically insulative material disposed intermediate said adjacent face-to-face areas of said electrically conductive sheet material.
