A container 10 and method of making the same preferably from a single web of flexible material wherein the method comprises placing a V-fold, or modified flat V-fold, in a sheet of such material, creating two subsections whose V-fold members (58, 60) are attached to the respective subsections preferably along a longitudinal fold line. First and second side edge weld lines (100, a,b) are made thereby connecting the respective subsections to their own V-fold members (58, 60) as well as those of the opposite subsections. Oblique weld lines (86, 88) then interconnect the point of intersection of the side edge weld lines (66,76) and longitudinal fold line. The bottom wall (2) is formed by folding the legs (80, 82) inwardly with the endmost portions of which pivoting along a lateral axis of the bottom wall (2) upwardly towards the first and second side edge weld line (100, a,b) thereby reinforcing the stress-bearing bottom.
