Abstract
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.
