To provide a bag making-packaging machine of which the structure is simple, and which is equipped with the function for adjusting the meandering of a film.

This packaging machine 100 is equipped with a first film carrying member 2 and a second film carrying member 4. In this case, the first film carrying member 2 is installed on the upstream side of a former section 3 and driven by a first driving source 22. The second film carrying member 4 is installed on the downstream side of the former section 3 and driven by a second driving source. Also, a control section 8 corrects the meandering of the film by rotating the attaching position of the attaching mechanism 24 of the first film carrying member 2 in the lateral direction by a specified amount conforming to the meandering amount and the meandering direction which have been sensed by a meandering sensing section 7.
