A packaging system includes a bag feeding device for forming a packaging bag series having a continuous bag portion partitioned by a side seal portion from a long film and a bag mouth opening/closing device having a conveying path formed between a conveying device for pulling and conveying the packaging bag series with first grips and a guide rail parallel to the conveying path. The movers traveling on the guide rail has second grips for gripping the side seal portion. By controlling and adjusting the distance between one mover and the mover immediately after that, an upper end opening of the bag portion is opened or closed according to various processes of the packaging process.

A system for controlling registration on a pouch knife machine of a longitudinally extending bandolier of content containing pouches separated by transverse seal seams moving along a feed path, with each pouch having a measurement reference. The machine includes a knife mechanism, a friction drag mechanism, and a friction drag adjustment mechanism. The system includes an optical reference, an optical image sensor, and a controller. The controller is configured to determine an actual position of the measurement reference relative to an optical reference, determine an alignment input based upon the actual position of the measurement reference relative to the optical reference, determine an alignment difference between a target position and the alignment input, and generate an adjustment command to change the position of the bandolier along the feed path after the alignment difference exceeds the operating range for the target position.

A packaging material having a core layer and inside and outside laminate portions is provided. The packaging material comprises a first area to form a first package, and a second area to form a second and adjacent package. The first area and the second area have a transversal sealing area between them, and the core layer is provided with at least one weakening portion at the transversal sealing area.

A first film can be conveyed through a horizontal form-fill-seal machine that contains tooling stations in which bottom sealer bars are positioned in different tooling stations relative to side sealer bars. The first film can be processed by the machine to form a first pouch. After the first pouch is formed, a vertical height of one or more of the side sealer bars and/or one or more of the bottom sealer bars can be selectively adjusted. The same bottom and side sealer bars remain in the machine during the selective adjusting of the vertical height. After the selective adjusting of the vertical height of the component, a second film can be conveyed through the horizontal form-fill-seal machine. The second film can be processed by the machine to form a second pouch having at least one dimension that is different than the first pouch.
