Abstract: A packaging material and a method of forming the packaging material into a flexible, disposable food container adapted to contain and maintain food in a fresh and sanitary condition, and to ship, display, heat and brown, and serve the food is disclosed. The method includes forming patches of microwave interactive material on a web of plastic and laminating the web of plastic to one side of a web of structural stock material to form a composite web; the microwave interactive material is sandwiched between the web of plastic and the web of structural stock material. Sealant is applied to portions of the plastic layer in registry with the patches of microwave interactive material to seal ends of the composite web. Printed graphics are applied to portions of the structural stock material layer in registry with the patches of microwave interactive material and the sealant. The formed container is sufficiently flexible to contain food having curved and irregular surfaces and to maximize contact of the food with the portion of the container housing the microwave interactive material. The container is sealed so that portions of the composite web extend as fins beyond the sealed ends of the food-containing portion of the container. The container also is capable of receiving food before the food is frozen to prevent portions or parts of the food from falling out of their proper place in the food packaging process.

Abstract translation: 公开了一种包装材料和将包装材料形成为柔性的一次性食物容器的方法，该食品容器适于容纳和保持食物处于新鲜和卫生状态，并且运送，展示，加热和褐色以及服务于食物。 该方法包括在塑料纤维网（14）上形成微波相互作用材料（18）的贴片，并将塑料纤维网层压到结构原料（12）的纤维网的一侧以形成复合纤维网（10）; 微波互动材料夹在塑料网和结构原料的网之间。 将密封剂（20）施加到塑料层的与微波相互作用材料贴片对准的部分以密封复合纤维网的端部。 印刷图形（24）被应用于与微波交互材料和密封剂的贴片对齐的结构原料层的部分。 形成的容器具有足够的柔性以容纳具有弯曲和不规则表面的食物，并且使食物与容纳微波交互材料的容器的部分的接触最大化。 容器被密封，使得复合织物的一部分作为翅片延伸超过容器的含食物部分的密封端。 在食物被冷冻之前，容器还能够接收食物，以防止食品的部分或部分在食品包装过程中脱离适当的位置。
