Abstract
An inflatable dunnage bag comprises a first inflatable inner bag comprising an inflatable bladder surrounded by at least one paper ply, and a second outer bag comprising at least one paper ply, or two or more paper plies whereby the number of paper plies comprising the entire composite inflatable dunnage bag, that is, the number of paper plies comprising the inner bag and the number of paper plies comprising the outer bag, is an odd number of paper plies. Consequently, the number of paper plies required to fabricate an inflatable dunnage bag, while maintaining the structural integrity and burst strength characteristics thereof for predetermined load applications, is effectively reduced with respect to currently manufactured dunnage bags.
