Bag-in-bag combination dunnage airbag

摘要

An inflatable dunnage bag comprises a first inflatable inner bag comprising an inflatable bladder surrounded by a pair of paper plies, and a second outer bag comprising two sets of paper plies disposed upon opposite sides of the first inner bag. The two sets of paper plies comprising the second outer bag are longitudinally offset with respect to each other so as to form flap members on first ends of each set of paper plies which overhang respective second ends of the opposite set of paper plies. The flap members are respectively folded over the second ends of the opposite set of paper plies as single entities and secured thereto by predetermined hot melt adhesive and cold glue bead patterns. The dunnage bag is thus particularly adaptable to being fabricated by automated equipment.
