The paperboard has at least three layers, a smooth first layer, a smooth third layer and a corrugated layer interposed between the first and third layers. The top member has an unsealed interior surface so that it can absorb moisture from a contained food product. The bottom member has a grease barrier layer within the interior of its paperboard preferably positioned on the top surface of the third layer. Each of the members have engageable peripheral rims, which have a releasable, rebondable cohesive applied to the rims to permit the members to be bonded together, separated and rebonded together.
