Abstract:
1. An apparatus for making inflated containers from a film web having two juxtaposed film plies, comprising: a. a first sealing device for producing a series of transverse seals that bond the film plies together; b. an inflation assembly for directing gas between the film plies; c. a second sealing device for producing one or more longitudinal seals that bond the film plies together, said transverse seals and said longitudinal seals intersecting to enclose the gas between the film plies to thereby form one or more inflated containers; and d. at least one intermediate sealing element for producing one or more intermediate seals that bond the film plies together, said intermediate seals partitioning said containers into two or more compartments and providing at least one flow passageway between said compartments to allow said compartments to fluidly communicate with one another, wherein, said intermediate seals provide the inflated containers with hinge-like flexible regions.
