ABSTRACT:
A container for packaging frozen food in which the food can be reheated including a paperboard tray having upstanding side walls and horizontal flanges and an upright central divider wall forming separate food compartments in the tray. The container is formed from a planar die-cut blank in which the central divider wall is formed by folding adjacent rectangular panels on the blank into abutting, back-to-back relation and the side walls are one piece and are foldably connected to adjacent die-cut portions of the blank so that when the divider wall is erected, the side walls are continguous to each other about the periphery of the tray. A pre-formed, semi-rigid blister of thermoformable plastic material is used in combination with the tray to provide a leakproof liner.
