ABSTRACT:
The specification discloses a method for packaging hot foods in a unique container having an inner layer of absorbent paperboard adhered to an outer layer of resinous foam insulating material. The inner paperboard layer has an absorbent porous surface and has sufficient thickness and rigidity to lend body to the container. The outer foam layer is sufficiently thick to insulate and prevent moisture leakage.
