A perforation forming module for a packaging machine of the type converting strip material into a strip of interconnected packets, the module comprising first and second punch die assemblies disposed along a strip feed path and reciprocally moveable between a retracted position away from the feed path and closed mutual engagement on the feed path. The movement of the punch assemblies into their operative closed positions is synchronized with upstream clamping engagement between sealing jaws and the strip material so that the perforation operation occurs while the strip material is held in tension between upstream clamping jaws and downstream pull-down rollers.
