These rollstock flat pouch packaging machines with 2-nozzle filling integrate two complete packaging lanes into a single HFFS system. Both lanes share the same drive and control platform but work in parallel, so pouch forming and dosing are carried out simultaneously under the same horizontal sealing unit. This double lane (2-nozzles) design allows output to be much higher than that of single-nozzle models, which is suitable for large-scale production of the same product where high speed and stable, continuous operation are required.
