Abstract: A bottom-gusseted package comprising a package body, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the bottom-gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the flexible web is folded and cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Attendant to folding of the flexible web, each gusset-forming sleeve is folded. Optionally, the individual sleeve portions can be configured such that when the flexible web is cut to form individual packages, each individual sleeve is cut to form a bottom gusset in one package, and a top sleeve portion in an adjacent package.

During package formation, the flexible web is cut to form individual packages, with each individual sleeve positioned to form a bottom gusset in a respective package. Cooperating heat-sealing jaws, including cooperating U-shaped sealing surfaces, act to integrate and seal each individual sleeve with the flexible web to form the bottom gusset of each package, with the heat-sealing jaws preferably configured to include cooperating top sealing surfaces for simultaneously forming a top seal in an adjacent one of the packages.

Abstract: A bottom and side gusseted package comprises a package body, a pair of inwardly extending side gussets, and a bottom gusset positioned transversely of a longitudinal axis of the package body. Formation of the gusseted package is effected by positioning individual sleeves transversely of the longitudinal axis of a flexible web which forms the package body. During package formation, the inwardly extending side gussets are formed, and the flexible web is cut to form individual packages, such that each individual sleeve forms a bottom gusset in a respective one of the gusseted packages.

Abstract: Reclosable bags, plastic film for making the bags, and a method and apparatus for making the bags are disclosed. The bag has a reclosable fastener (26) connected to a single wall of the bag, and the film (55) has a reclosable fastener (26) connected to one side thereof which does not require attachment to any other portion of the film (55) when making a bag. The fastener (26) has a tamper-proof member attached thereto to indicate if the bag has been previously opened. The film (55) can be wound into a roll (54) suitable for use on conventional bag making machines including form, fill, and seal machines or a chain of coilable reclosable bags can be produced therefrom since the fasteners (26) are connected to the web preferably transversely to the bags longitudinal formation axis.

Abstract: A method of making a recloseable package having a slider zipper assembly includes advancing a web of a plastic film material in a direction along a longitudinal axis thereof, and applying a plurality of profile strip fastener assemblies to the plastic film material transversely of the longitudinal axis. A slider is applied to each of the fastener assemblies so that movement of each slider along the length of the respective one of the fastener assemblies moves the pair of profile strips thereof into and out of interlocking engagement. Opposite side edges of the plastic film material are joined to form a tube, with seals formed transversely of the tube to form a top seal and a bottom seal for each of the packages. The package is configured such that the slider projects generally through the front wall of the package, with the front wall optionally being provided with a frangible region in the form of a line of weakness aligned with the fastener assembly.

Abstract: A package in the form of a reclosable 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, with a secondary, peelable seal provided between the profile strips apart from their mechanically interlocked portions. By this arrangement, enhanced sealing for the package is provided, while abating the stress to which the interlocked portions of the profile strips are subjected during forming and filling of the package. The bag body preferably includes a frangible joint substantially aligned with the fastener assembly for gaining access to the assembly, with the frangible joint desirably providing tamper-evidence of opening of the package. The profile strips are sealed to the front wall of the bag body with a continuous oval shaped seal around the frangible joint. The perimeter seal is located above the peelable seal.

Abstract: A closure element incorporated into a flexible bag to reclose a bag opening includes a resilient structure which carries an adhesive strip. The closure element is secured to one wall of the bag and the resilient strip seals the one wall to the respective other wall of the bag when the walls are pressed together and the resilient structure is compressed. The resilient structure is held compressed by the adhesive strip. In one embodiment, the resilient structure includes a base portion and a wing portion which deflects to allow the adhesive strip to make contact with the other wall. In another embodiment, the base portion deflects to flatten against the wing portion, the wing portion secured to the bag wall. The base portion and the wing portion can be provided with engageable elements which snap together or interlock to provide a closing feel to the closure strip as the adhesive strip seals the bag opening.
