<p>A package blank and a packaging method for wrapping flat articles, such as diskettes, cassettes and books. A flat sheet of paperboard or cardboard is provided with a rectangular mid-section (1) defined by four bending lines (3, 5), one along each side of the rectangle. The sections beyond the sheet bending lines (3, 5) provide two side flaps (2) and two end flaps (4). The side flaps (2) defined by the longer bending lines (3) have a total width which exceeds the width of the rectangular mid-section (1). An article to be wrapped is placed on top of the rectangular mid-section (1) of a flat sheet and the side flaps (2) are folded along the bending lines (3), on top of the article to be wrapped. The side flaps (2) include overlapping sub-areas (2a) which are sized into contact with each other, whereby the side flaps (2) are subjected to a flexural stress between the bending line (3) and the overlapping sub-areas (2a). Finally, the end flaps (4) are folded along the bending lines (5), and the folded end flaps (4) are sized against the outer surfaces of the side flaps (2). <IMAGE></p> |
