An oral tobacco pouch product includes a pouch wrapper formed of a web having a longitudinal integrated fin and lap seal. The pouch wrapper contains a filling material including tobacco material and optional additives. The longitudinal integrated fin and lap seal is formed on a forming collar.

The invention provides a method of manufacturing packaging comprising the steps of: a) providing a packaging material (2) comprising cartonboard, semi-rigid plastics or other semi-rigid packaging material; b) forming fold lines (8) and/or cuts within the packaging material (2) by subjecting the packaging material (2) to laser (12) or mechanical scoring; c) folding the packaging material (2) along the fold lines (8) and/or cuts and securing in position to form a substantially tubular container (200); and d) forming at least one seal (302, 304) by sealing together at least two opposing regions (122, 124, 126, 128) of a blank (4) to form an at least partially sealed package (300); e) performing at least one of steps b), c) and d) on a horizontal or vertical fill, form and seal apparatus (400).

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.

Apparatus (10) for producing tubular packages includes a packaging material dispenser (12) and a forming section (20). The forming section (20) comprises a progressive folding region (26a, FIG. 8) having a plurality of discrete, elongate external guide surfaces (50, 52, 54, 56) extending generally in the machine direction (A). The elongate external guide surfaces are spaced apart from one another and configured for contact with an outer surface of the packaging material so as to progressively guide and fold the packaging material about a longitudinal axis from a planar configuration into a tubular structure. The elongate guide surfaces may be arcuate and may be provided by means of guide rods. 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.

A vertical form, fill, and seal (VFFS) machine and method for producing an oral sachet designed to be placed in a users mouth, the oral sachet. The oral sachet includes permeable paper that does not contain fiberglass. The permeable paper forms a pouch that includes a top seal arranged at first end of the pouch, a bottom seal arranged at a second end of the pouch opposite from the first end, a vertical seal that extends from the top seal to the bottom seal, and a cavity located between the top seal and the bottom seal. Granular contents, including at least one granular or powdered component, are arranged within the cavity of the permeable-paper pouch.

A first film can be conveyed through a horizontal form-fill-seal machine that contains tooling stations in which bottom sealer bars are positioned in different tooling stations relative to side sealer bars. The first film can be processed by the machine to form a first pouch. After the first pouch is formed, a vertical height of one or more of the side sealer bars and/or one or more of the bottom sealer bars can be selectively adjusted. The same bottom and side sealer bars remain in the machine during the selective adjusting of the vertical height. After the selective adjusting of the vertical height of the component, a second film can be conveyed through the horizontal form-fill-seal machine. The second film can be processed by the machine to form a second pouch having at least one dimension that is different than the first pouch.

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.

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 device or similar structure.

The presently disclosed subject matter is directed to a pouch for cooking a food product and a method of making a pouch for cooking The pouch for cooking a food product may have a film, a longitudinal seal so as to form a sealed tube, a first transverse seal at a first end of the pouch, and a second transverse seal at a second end of the pouch. The pouch may have a surface area to food product volume ratio from 3:1 to 9:1. The pouch may have at least one layer with at least 5% polybutylene. The longitudinal seal may extend from the first end of the pouch to the second end of the pouch. The longitudinal seal may seal the film to itself.

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.
