Abstract
An inflatable dunnage bag is comprised of a first and independently sealed bag that is inserted within a paper tube before the tube ends are sealed to form a second, independent bag. The combination of an inner bag within an outer bag provides increased bursting strength compared to similar ply bags created as only a single bag. The combination bag is much easier to construct since at least two plies of paper that are pressed to form the inner bag are no longer part of the bag end folding and sealing process. This is especially true if the outer bags ends are sealed by stitching them together.
