A food container comprising three or more plies, a first ply, a second ply, and at least a third ply. The first ply is oriented towards the hands and face of the user and receives food in use. The first ply is essentially continuous throughout its plane. The third ply is oriented towards the lap of the user or a table top in use. The second ply spaces the first and third plies apart. In a preferred embodiment, the food container may be made of a corrugated material. The food container may be made from a blank which is deformed out of its plane during manufacture.
