Abstract
A food package is provided wherein the accommodated food product, while remaining in the package, may be heated or cooked in a microwave oven. The food product has at least one predetermined portion thereof which requires enhanced heat while the product is being heated or cooked in the oven. The food package includes a container formed of heat resistant material which is pervious to the microwaves. A surface of the container is provided with an area which is in proximity to the predetermined portion of the food product requiring the enhanced heat. A metallized ink, consisting of metal particles suspended in an ink-like substance, is deposited on the surface area of the container. Thus, when the metallized ink is exposed to the generated microwaves, the required enhanced heat is produced in the vicinity of the surface area.
