Microwave packaging with indentation patterns

The notch pattern (116a, 116b) can crease the packaging material (100) for microwave ovens, and is formed, and the packaging material (100) for microwave ovens in food roasts it, and it increases an effect and a browning-ized effect. It prevents that pass moisture from one zone of food to another zone, take in moisture with a notch pattern (116a, 116b), and moisture is emitted, or moisture is completely passed away from food, and discharge is brought about. With a notch pattern (116a, 116b), the packaging material (100) for microwave ovens under food is slightly lifted above the kitchen counter in the base of a microwave oven. The void for heat insulation is prepared with a notch pattern (116a, 116b), and the heat sink effect of a kitchen counter decreases. If the base of the packaging material (100) for microwave ovens is raised, the entering microwave radiation line, food -- or it is absorbed by the microwave interaction material in the packaging material (100) for microwave ovens which promotes heat-treatment, and can spread further below the packaging material (100) for microwave ovens.
