ABSTRACT:
an inflatable packaging material comprises a plurality of flexible bladders formed of tubes sealed at one end and partially sealed at the other end to provide a passageway which may be closed by a stopper. In one embodiment, a protuberance extends from the sealed end of each bladder which may releasably engage the walls of a passageway of an adjacent bladder to join the bladders end-to-end. In a second embodiment, the sealed end includes an eyelet and the passageway end includes a stopper attached to such end by a flexible trunk such that the stopper of one bladder may releasably engage the eyelet of an adjacent bladder to join the bladders end-to-end. The bladders may line a carton to protect an article shipped therein.
