ABSTRACT A paperboard flat blank is scored for folding to form a container sleeve. The flat blank comprises at least first and second flat blank portions which have been sealed together along a seal line or lines to form the entire, flat blank. The majority of the area of each flat blank portion is free of contact with the other flat blank portion, i.e., the respective portions are not separate layers of a flat blank, but are separate, spaced portions thereof, connected together by one or more seal lines. The first flat blank portion exhibits at least one physical property that is different from the corresponding physical property of the second flat blank portion, other than the scoring and the shape and size in the plane of the flat blank. For example, one flat blank may be made of recycled material and the other of virgin material. The two flat blanks may have different thicknesses, or differing surface treatment, one being impregnated with oil or plastic and the other being free of such impregnation, or the like. The flat blank is made with at least a pair of mirror imaged walls that abut each other to form a double panelled wall when the flat blank is assembled into a four-cornered container. Also, there are double panelled corner tab portions that improve the stackability of the containers assembled from the blanks by providing great strength at the corners thereof.
