    • 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.
    • 压痕图案在微波包装材料中得分,以提高微波包装材料在食品上的烘烤和褐变效果。 压痕图形提供了从食品的一个区域到另一个区域的通道水分的通风,在特定区域捕获水分以防止其逸出,或将水分完全远离食品。 压痕图案使得食品产品下面的微波包装材料在微波炉底部的烹饪平台上略微升高。 压痕图案通过提供用于绝缘的气隙来减少烹饪平台的散热效果。 提升微波包装材料的基底还允许更多的入射微波辐射传播到微波包装材料的下面,以被食品吸收,或者通过微波包装材料中的微波相互作用材料来增加加热过程。
