Abstract: An improved top opening, rectangular flexible bag for containing a stack of highly compressed flexible articles. The bag has front and back panels, two side panels and top and bottom panels, all of which are connected together to form an internal compartment for containing the stack under high compression. The stack is arranged within the bag in such a way that the side panels are under tension.

Abstract: To make plastic carrying bags or sacks, sections are cut or are severed by hot wire welding from a gusseted tubular film by a formation of transverse seam welds and transverse severing cuts or by hot wire-welded transverse seam welds. At least in their bottom portion the sections are provided with corner seam welds, which are separately formed in the two folds and which diverge obliquely from the outer fold lines toward the top and/or bottom seam weld and terminate short of the inner fold line and merge into the latter.
