Abstract
A process for forming fluid filled units is disclosed. In the process, a web having a series of side connected pouches are fed to an inflation station. The pouches are connected by a line of perforations. 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. The pouches filled with fluid and sealed to form fluid filled units.
Claims9
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 each line of perforations includes longer perforations and more than one shorter perforation that is shorter in length than the longer perforations, wherein the shorter perforations extend from an inflation opening of each pouch and the longer perforations of each line of perforations extend from the shorter perforations toward a side edge of each pouch;
- b) fluid filling the pouches as the web is fed through the fill station;
- and
- c) sealing the pouches to form filled units.
A process of forming fluid filled units comprising:
- a) inserting a fill nozzle into a space between two layers of a plastic 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 each line of perforations includes longer perforations and more than one shorter perforation that is shorter in length than the longer perforations, wherein the shorter perforations extend from an inflation opening of each pouch and the longer perforations of each line of perforations extend from the shorter perforations toward a side edge of each pouch;
- b) advancing the web over the nozzle while concurrently fluid filling the pouches with fluid;
- and
- c) sealing the filling pouches to form fluid filled units.
