An octagonal container is formed from corrugated paperboard with overlapping flaps for eliminating gaps in the container bottom wall. Prestretched polypropylene straps are automatically applied to the container when in its flattened condition for providing girth support to the container when in its erected condition. The straps are positioned from the lower portion of the container side walls at ever increasing distances from each other for limiting container bulge when carrying products having varying effects on the container. With such an arrangement of straps, economically and environmentally desirable single and double wall corrugated paperboard can be used where typically triple wall and laminated paperboard containers are used.
