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 seond end of the trnaverse seals, thereby forming a shirt that extends between adjacent containers at the open longitudinal edge. Such skirt facilitates inflation of each container.
L'invention concerne un appareil permettant de former des récipients gonflables qui comprend une bande de film composée de deux plis de film juxtaposés, d'un bord longitudinal fermé, d'un bord longitudinal ouvert, et d'une série de scellements transversaux dont une première extrémité est située au niveau du bord longitudinal fermé et une seconde extrémité se termine à une distance prédéterminée du bord longitudinal ouvert, de sorte que chacun des plis de film juxtaposés présente une section s'étendant au-delà de la seconde extrémité des scellements transversaux, ce qui permet de former une jupe s'étendant entre des récipients adjacents au niveau du bord longitudinal ouvert. Cette jupe facilite le gonflement de chaque récipient.
