First Claim
1. An inflatable dunnage bag, comprising:
- an air-tight inflatable bladder;
first and second sets of paper plies, wherein each one of said first and second sets of paper plies comprises a plurality of paper plies, and wherein further, said first and second sets of paper plies are disposed upon opposite sides of said air-tight inflatable bladder;
at least one flap member formed at one end of a first one of said first and second sets of paper plies and projecting beyond one end of a second one of said first and second sets of paper plies so as to be capable of being folded over said air-tight inflatable bladder and thereby extend from a first side of said air-tight inflatable bladder to a second side of said air-tight inflatable bladder and be secured to at least one of said paper plies comprising said second one of said first and second sets of paper plies;
means for securing said at least one flap member of said first one of said first and second sets of paper plies to a region of said at least one of said paper plies comprising said second one of said first and second sets of paper plies which is disposed upon said second side of said air-tight inflatable bladder so as to close and seal said dunnage bag; and
means fixedly mounted and sealed upon said first side of said air-tight inflatable bladder for inflating said air-tight inflatable bladder such that said inflating means is disposed upon the side of said air-tight inflatable bladder which is opposite the side of said air-tight inflatable bladder upon which said at least one flap member is secured to said region of said at least one of said paper plies comprising said second one of said first and second sets of paper plies whereby said inflating means is disposed remote from said region at which said at least one flap member is secured.

Abstract
An inflatable dunnage air bag comprises a multi-layered paper bag and an inflatable bladder disposed within the multi-layered paper bag such that two sets of paper plies are disposed upon opposite sides of the inflatable bladder. The multi-layered paper bag has at least one flap member extending outwardly from one set of paper plies and is adapted to extend from a first side of the inflatable bladder and be folded over and secured upon the other set of paper plies so as to be secured at a location disposed upon the other or second side of the inflatable bladder. An inflation valve is fixedly secured to the first side of the inflatable bladder so as to facilitate inflation thereof, the inflation valve thereby being disposed remote from the location at which at least one flap member is secured so as not to present additional weakening forces or stresses within the already high-stress flap securing region. Enhanced burst strength values are achieved with the inflatable dunnage air bag having such aforenoted interrelated structure.
