1. A method of forming a package with a recloseable pour spout, comprising the steps of:
providing a web of material having a longitudinal axis;
applying a plurality of fastener strips to said web of material at intervals corresponding to a length of each said package being formed, said fastener strips each extending transversely off center of said longitudinal axis and each consisting of a single fastener strip being detachably connectable to itself by folding and pressing against itself;
folding said web of material, and sealing the material to itself to form a tube;
transversely sealing said tube to form a series of packages in end-to-end relationship, with each said package including a front package panel and a rear package panel, with a respective one of said fastener strips extending from the front panel to the rear panel of the respective package to form a recloseable pour spout, and
forming a pair of inwardly extending side gussets in said tube, said web of material with attached fastener strips being guided with respect to suitable plows which form said side gussets parallel to said longitudinal axis prior to said transversely sealing of the tube, each said fastener strip extending from the front panel to the rear panel of the respective package along an inside surface of a respective one of said side gussets, wherein said fastener strip has a pair of leg portions respectively extending along said front and rear panels inwardly beyond said one of said inwardly extending side gussets.
