Zusammenfassung:	A bladder device (20) is for moving a component of a web packaging machine (2) that forms and encloses a food product in a food product package made of webs of packaging material. The bladder device (20) has a bladder (21) and a nipple stub (30) coupled to the bladder (21) and having a first end (31) configured to receive a gas and a second end (32) configured to dispense the gas into the bladder (21) to thereby inflate the bladder (21) and move the component of the web packaging machine (2). A collar (60) coupled to the nipple stub (30) such that the bladder (21) is sandwiched between the collar (60) and the second end (32) of the nipple stub (30). The second end (32) of the nipple stub (30) has a depression (38) and the collar (60) has a boss (62) that is oriented towards the depression (38) such that tightening the collar (60) on the nipple stub (30) forces the bladder (21) into the depression (38) and thereby forms a fluid tight seal.
