A packaging machine includes a compact dynamic shuttle buffer arranged upstream of a packaging station.

A form-fill-seal packing apparatus of the flow wrapper type accepts individuated items via in-feed conveyor. Items are moved through horizontal open lower-sided forming tube 10 by resting indirectly on an underneath transit conveyor, through the underside part of a continuous film bag forming from a supply of film around the forming tube, using a forming shoulder. The bag is longitudinally sealed beside the forming tube. Data may be printed on an upper film surface over a platen including an upper part of the forming tube. An outfeed conveyor carries transversely sealed wrapped items on to a vacuum sealer.

A pouch having improved delamination property and a process for making the pouch includes the steps of (I) providing a film structure and (II) preparing a pouch from said film structure provided in Step (I). The film structure comprises a core layer of at least one biaxially-oriented hygroscopic polymer, and the film structure comprises, on at least one side adjacent to the core layer, an adhesive layer comprising Pacacel adhesive.

A film fin sealing device is disclosed herein which may have a groove defining a base. The base of the groove of the fin sealing device may be oriented at a skewed angle with respect to a longitudinal direction of the conveyor of a heat sealing machine. Edges of a thermoplastic sheet or two stacked layers of thermoplastic sheets are introduced into the groove of the film fin sealing device and placed in contact therewith to both heat and fuse the distal edge portions of the thermoplastic sheet(s) to join the edge portions thereof to form a fin seal.

Apparatus (10) for producing tubular packages includes a packaging material dispenser (12) and a forming section (20). The forming section (20) comprises a series of package formers (22a-22e) aligned in the machine direction, each defining a packaging material folding channel (24) through which the packaging material passes. The channels (24) of the package formers in the series vary in shape such that as the packaging material passes through the forming section it is gradually folded about a longitudinal axis from a planar configuration into a tubular structure. A series of items (44) to be packaged is conveyed in the machine direction and may be sequentially introduced proximal to the packaging material (14) at a location such that the packaging material is subsequently folded about each item in turn as it continues through the forming section. The apparatus may be a horizontal or vertical form, fill seal type apparatus. The packaging material (14) may be a semi-rigid packaging material such as paperboard, cartonboard, or semi-rigid plastics.

An exemplary embodiment of a cold seal package forming device (100) is provided, which may have a scoring device configured to score a continuous film laminate, the film laminate comprising a layer of pressure sensitive adhesive/PSA (36) disposed between a first film layer (37) and a second film layer (38); a stripping device configured to strip at least a portion of the second film layer (38) to expose the PSA (36); a forming device configured to form the film laminate into a package (30) having an interior; a feeding device configured to feed a product into the package interior; a sealing device (108, 142) configured to seal the product within the package interior via adherence of the exposed PSA (36) on a portion of a package periphery; and a separating device configured to singulate the package (30) from a continuous web of the film laminate.

A vertical bag-making/filling/packaging machine (1) includes: a top folding portion (20) which forms a first fold (F1) by folding a side of a band-shaped film (F) into a Z-shape; a bottom folding portion (30) which forms a second fold (F5) by folding a center of the film (F) into an M-shape; a top seal portion (40) which forms a top gusset (G3) and a spout portion (G7) protruding from the top gusset (G3) by heat-welding the first fold (F1) and side edges (E1 and E2) of the film (F) so as to make the film (F) into a tube shape; and a bottom-seal portion (50) which forms a bottom gusset (G4) by heat-welding the second fold (F5).

This disclosure pertains to a forming device used in the formation of a package with a self-mating reclosure, where a single self-mating closure wraps around the periphery of the forming device, and one end of the zipper segment extends into the lap seal of the forming device. Alternatively, one or two ends of the zipper segment could extend into a fin seal. The self-mating reclosure is mounted transversely on the sheet of web or film and includes at least one crushed end proximate to one edge of the sheet of web or film. The self-mating closure may be pre-crushed, prior to attachment to the sheet of web or film, or may be crushed after the sheet of web or film is wrapped around a forming forming device or similar structure.

The present invention relates to a device for sealing a packaging material (10), comprising at least one sealing installation (18) which comprises at least one coil core (24) which is surrounded by at least one coil (25), wherein the coil core (24) has at least one gap (32) through which packaging material peripheries (34, 36) to be sealed are guided, wherein at least one element (23) that conducts a magnetic flux is provided, said element (23) for influencing a region (22) of the packaging material peripheries (34, 36) to be heated being disposed so as to be adjacent to the packaging material peripheries (34, 36) to be sealed.

The present invention relates to a sealing device (1, 101, 201) for sealing a packaging material (7, 107) enclosing a filling material (29) to provide portion-packed oral pouched snuff products (43). The sealing device comprises an anvil (3, 103, 203) with a first operation surface (11, 111, 211) and a sonotrode (5, 105, 205) with a second operation surface (13, 113), the anvil and the sonotrode being arranged to allow passage of the packaging material therebetween, the second operation surface being located opposite the first operation surface during operation of the sealing device. The first and second operation surfaces are arranged to weld a first portion (7a, 107a) of the packaging material to a second portion (7b, 107b) of the packaging material. At least one of the first or second operation surfaces comprises a first welding surface (11a, 111a) defining a first extension plane and a second welding surface (11b, 111b) defining a second extension plane, which has a different orientation than the first extension plane. The first and second welding surfaces are partly delimited by a cutting edge (15, 115, 215) having an extension direction along the first and second welding surfaces, such that the cutting edge separates the first welding surface from the second welding surface. The present invention further relates to an arrangement (19) for manufacturing of portion-packed oral pouched snuff products, which arrangement comprises such a sealing device. The present invention also relates to a method for portion-packing of an oral pouched snuff product.
