Abstract
A package preparation system includes a material conveyable along a longitudinal direction and including two folded layers of polymeric film joined at a fold. The fold extends longitudinally and defines a first side of the material opposite an open second side. A first welding device forms partition welds located between the two folded layers and extending from the fold to a terminus inward of the open side. A second welding device forms first and second seal welds that extend from the fold to the open side and are spaced from each other by a length extending longitudinally and traversing a plurality of the partition welds. The system includes a device comprising a nozzle insertable in the open side, and clamps that traverse the length and temporarily seal the open side around the nozzle while the nozzle inflates interior channels defined between the plurality of partition welds.
