Abstract:
1. A process of forming fluid filled units comprising: a) feeding a web having a series of side connected pouches that are each connected to an adjacent pouch by a line of perforations from a supply to a fill station, wherein first perforations of the line of perforations that extend from an inflation opening of each pouch are shorter than second perforations of the line of perforations that extend from the first perforations toward a side edge of each pouch; b) fluid filling the pouches as the web is fed through the fill station by directing fluid under pressure through a nozzle into the web pouches; c) maintaining the web in close surrounding relationship with the nozzle during the filling step to limit the loss of fluid under pressure from the web; and, d) sealing the pouches to form filled units by engaging the web with belts and passing engaged web portions under coacting heating and cooling shoes.
