The present invention is a bag making machine (20, 30). The bag making machine (20, 30) includes: a conveying unit (37) which conveys a multi-layer film (S) in which films (13a, 13b) are overlapped; a side edge sealing device (27) which thermally fuses the films (13a, 13b) to each other; and an ultrasonic device (26) which crushes a part of a zipper member (14) disposed between films (13a, 13b). The side edge sealing device (27) includes: a platform (44); and a heat-generating head (45). The ultrasonic device (26) includes: an anvil (41); and an ultrasonic horn head (42). The heating-generating head (45) and the ultrasonic horn head (42) reciprocate at a same cycle via a link member (51).

A method of forming reinforced packages. The method can comprise forming an attached web by adhering a blank to a web of material and moving the attached web in a downstream direction through at least a tube forming assembly and a carton forming assembly. The method also can comprise at least partially forming a tube by folding at least a portion of the web of material as the attached web moves through the tube forming assembly, forming a reinforcement sleeve by folding at least a portion of the blank so that the reinforcement sleeve extends at least partially around the tube as the attached web moves through the carton forming assembly, and forming a reinforced package comprising the reinforcement sleeve and a tube portion by separating the tube portion from a remainder of the tube, the reinforcement sleeve being adhered to the tube portion.

Embodiments of the present disclosure provide a reclosure, closure or zipper on a large format package or bag that is mounted to the top of the package or bag, which may be formed from a tube of polymeric material, with the ends of the reclosure, closure or zipper flush to the sides of the bag. The upper corners of the package or bag includes notches in the gussets. The area of the package walls around the notches is pinned, glued or sealed together and the closure is attached to the package walls. The ends of the reclosure, closure or zipper are flush with the side edges or seals of the package or bag.

A system for applying a fastening material to a substrate is provided. The system may include a first material source including the substrate. The substrate may define a first length extending from a first edge to a second edge and the first material source may feed the substrate in a first direction transverse to the first length. The system may additionally include a second material source including the fastening material. The fastening material may define a second length extending from a third edge to a fourth edge, whereby the second length is substantially equal to the first length and the second material source feeds the fastening material in a second direction transverse to the second length. The system may also include an applicator system that secures the fastening material to the substrate.

A zipper assembly for a reclosable enclosure includes a first profile having a first elongated supporting element and first protruding intermeshing elements. The zipper assembly also may include a second profile having a second elongated supporting element and one or more second intermeshing elements protruding from the second elongated supporting element. The one or more first intermeshing elements may releasably interlock with the one or more second intermeshing elements to close the enclosure. Each of the first elongated supporting element and the second elongated supporting element may include a thicker portion and a thinner portion. The thicker portions of the first elongated supporting element and the second elongated supporting element may be coupled with one or more panels of the enclosure. The thicker portions of the first elongated supporting element and the second elongated supporting element may be disposed on a consumer side of the enclosure.

A device and a method for applying cover sheets to cross-bottoms of tubular sections made of a plastic material. The device includes conveyor devices for transporting the tubular sections and for depositing the cover sheets on the cross-bottoms in a deposit area. The device includes a hot gas device with a gas heater and a nozzle connected to the gas heater and oriented toward the deposit area for the cover sheets so when gas is supplied to the gas heater, the gas flows along a flow path from the gas supply through the gas heater and the nozzle into the deposit area. The hot gas device has a hot gas reservoir with an internal volume for the temporary storage of hot gas, the flow path running through the hot gas reservoir. A gas mass flow ({dot over (m)}1, {dot over (m)}2, {dot over (m)}ges) of gas supplied to the gas heater is adjustable by a control.

A bottle pouch with an integrated fitment and inner support handle piece includes a flexible pouch in the shape of a bottle including a flexible pouch body with a handle region, and a combined fitment and inner support handle piece including a rigid handle portion extending from the combined fitment and inner support handle piece. The combined fitment and inner support handle piece is coupled to the flexible pouch. The inner support handle piece extends from the inside of the fitment and is internal to the flexible pouch body and passes from the interior to the exterior of the flexible pouch body adjacent to the handle region of the flexible pouch body to form the rigid handle portion. In another form, the inner support handle piece extends from the outside periphery of the fitment and is external to the flexible pouch body, but is secured to the periphery of the flexible pouch body with one or more outer sleeves or loops.
