An inflatable cushion packaging machine including a housing, a driving mechanism disposed at a front side of the housing, a rolling shaft module disposed at a rear side of the housing, and a friction module is provided. A film roll is mounted to the rolling shaft module, wherein a free end of the film roll is engaged with and moved by the driving mechanism such that the film roll is dragged by the driving mechanism to rotate the rolling shaft module. The friction module assembled to the housing has a friction ring being coaxial with the rolling shaft module and a plurality friction rollers mounted to the friction ring. The friction ring is forced to lean the friction rollers against a side surface of the rolling shaft module and stop the rolling shaft module from rotating while the rolling shaft module not being dragged and rotated by the driving mechanism.
