Abstract (en)
A dunnage bag and method for making the bag are disclosed in which the bag casing has a plurality of outwardly extending end flaps (253a,253b) and a plurality of outwardly extending corner flaps (270a,270b) on each side of the end flaps (253a,253b). The end flaps are folded over at each end of the casing and secured to the opposite wall. The corner flaps (270a,270b) are folded inwardly and tucked inside the opposite wall to provide a support at each bladder corner to prevent dilatation of the bladder (232) during and after inflation.
