A corrugated paperboard wraparound blank for forming a shipping case is provided, including five wall panels and four sets of end flaps connected via fold lines, at least two sets of stacking tabs, and at least two corresponding sets of receiving slots for receiving the stacking tabs. The wraparound blank is formed of a heavier material than a conventional blank, which would typically be difficult for automatic packaging equipment to form into a case, but the fold lines are creased with optional perforations or scoring. An optional modification aiding folding is presented for conventional case packers. The heavier fiberboard better supports and protects an inner product, such as cartons or paper bottles of liquids and reduces damage to the cap and neck. The heavier material in combination with the stacking tabs allows an increase in stacking height, thereby reducing transportation costs.
