A stiff-walled carton-like container is formed from a laminate of flexible sheet material, the interply adhesive of which is a settable composition to give the container its stiffness. Before the adhesive sets the laminate is cut and folded into a flat bag, e.g. of the self-opening satchel or block-bottom types. The bag is erected to a carton-like shape and filled after the adhesive sets. The bag can be formed with overlapping bottom flaps peelably adhered together so that the container can be opened from that end by cutting off a corner of one flap, the other end of the container being permanently sealed after filling. |
