Abstract
An apparatus for forming inflated containers includes a film web that includes two juxtaposed film plies, a closed longitudinal edge, an open longitudinal edge, and a series of transverse seals having a first end located at the closed longitudinal edge and a second end terminating a predetermined distance from the open longitudinal edge such that each of the juxtaposed film plies have a section extending beyond the second end of the transverse seals, thereby forming a skirt that extends between adjacent containers at the open longitudinal edge. Such skirt facilitates inflation of each container.
