MICROWAVE PACKAGING WITH INDENTATION PATTERNS

摘要

Indentation patterns 116a, 116b are scored in microwave packaging materials 100 to enhance the baking and browning effects of the microwave packaging materials 100 on food products. The indentation patterns 116a, 116b provide venting to either channel moisture from one area of the food product to another, trap moisture in a certain area to prevent it from escaping, or channel the moisture completely away from the food product. The indentation patterns 116a, 116b cause the microwave packaging material 100 underneath a food product to be slightly elevated above the cooking platform in the base of a microwave. The indentation patterns 116a, 116b lessen the heat sinking effect of the cooking platform by providing an air gap for insulation. Elevating the base of the microwave packaging material 100 further allows more incident microwave radiation to propagate underneath the microwave packaging material 100 to be absorbed by the food product or by microwave interactive materials in the microwave packaging material 100 that augment the heating process.
