A package in the form of a recloseable bag includes a bag body including front and back walls, and a profile strip fastener assembly sealingly mounted on the inside surface of the front wall. The profile strip fastener assembly includes a pair of releasably interlocking profile strips. One of the profile strips is connected to the inside of the front wall of the bag, while the other one of the profile strips includes a flange portion which extends from the profile strips to and adjacent end seal of the bag. A method of forming recloseable bags is disclosed, which method can be employed with a form, fill, and seal machine for effecting the efficient packaging of products in recloseable bags.

[ What is claimed is:] [1.] A method of making recloseable bags, comprising the steps of:providing a substantially continuous sheet of film material;providing a plurality of fastener assemblies each comprising first and second interlocking profile strips each extending along the length of the respective fastener assembly, said profile strips being configured for releasable interlocking engagement with each other by the provision of at least one protuberance on one of the profile strips, and at least one groove defined by the other of the profile strips for respectively releaseably receiving said protuberance;connecting each of said fastener assemblies to a surface of said film material in spaced apart relationship to each other transversely to and along a longitudinal axis of said film material by connection of a first one of said profile strips of each said fastener assembly to said surface of said film material;folding said film material, and sealing lateral edges thereof to each other to form a tube enclosing said fastener assemblies; andsealing said tube of film material transversely to the longitudinal axis thereof to form a series of recloseable bags joined in end-to-end relationship,including providing a second one of said profile strips of each said fastener assembly with a flange portion, and sealing each said flange portion into said tube of film material during said transversely sealing of said tube of film material, each of said flange portions extending into an adjacent one of said series of recloseable bags joined in end-to-end relationship.
