1. An apparatus for forming inflatable containers in a film web having two juxtaposed film plies, the apparatus comprising:
a transverse sealing device configured to produce a series of transverse seals in the film web to bond the juxtaposed film plies together; and
an intermediate sealing device configured to produce a plurality of columns of discontinuous intermediate seals in the film web;
wherein the transverse seals form sides of inflatable containers in the film web and the film web has a closed longitudinal edge that forms a closed end of the inflatable containers;
wherein the intermediate seals are arranged to partition each inflatable container into a plurality of compartments;
wherein, in each of the inflatable containers, the intermediate seals provide at least one flow passageway between compartments to allow the compartments to fluidly communicate with one another.
