The flat-shaped composite material has a plurality of fold lines, which are arranged and designed such that a closed package can be manufactured by folding the flat-shaped composite material along the fold lines and by connecting seam surfaces of the flat-shaped composite material and a sleeve surface. The sleeve surface includes a front surface, a first side surface, a second side surface, a first rear surface, a second rear surface, and base surfaces. The base surfaces include triangular base surfaces, quadrangular base surfaces, and gable surfaces. The gable surfaces include triangular gable surfaces and quadrangular gable surfaces. The base surfaces and the gable surfaces are arranged on opposite sides of the sleeve surface. The manufacture of packages with even more complex geometries without impairing the rigidity of the package should be achieved by a third sleeve fold line, which has a plurality of sections, which each adjoin a side surface and a rear surface, and of which at least one section is curved and of which at least one section is straight. A package sleeve made of a composite material and a package manufactured from the composite material or from the package sleeve are also represented and described.

The present invention relates to a sheetlike composite comprising, as mutually superposed layers, a) a carrier layer, b) a barrier layer, and c) an inner polymer layer,
wherein the sheetlike composite has a multitude of groove lines arranged and configured such that, by folding the sheetlike composite along the groove lines and joining seam areas of the sheetlike composite thereby obtaining seams, a closed container is obtainable, wherein the closed container has a roof area, wherein a first portion of the groove lines of the multitude of groove lines at least partly forms a circumference of a first part-area of the roof area, wherein the groove lines of the first portion, relative to the first part-area of the roof area, have at least partly convex curvature, wherein the first part-area of the roof area has a first length in a longitudinal direction and has a second length in a circumferential direction at right angles to the longitudinal direction, wherein a ratio of the first length to the second length is in a range from 0.2 to 2.0. The invention further relates to methods of producing a sheetlike composite, a container precursor and a closed container, and to the aforementioned method products; to a further container precursor; to a further closed container; and to a use of the sheetlike composite.

The present invention relates to a method of manufacturing a laminated packaging material comprising a first, outermost layer of a transparent polymer, to be directed towards the outside of a package made from the laminated packaging material, a substrate layer, and a second, outermost layer of a thermo-sealable polymer, arranged on the other side of the substrate layer opposite to the first outermost layer, and optionally one or more further material layers between the substrate layer and the second, outermost polymer layer, the laminated packaging material exhibiting a visual or tactile pattern, or a combination thereof, in the first outermost transparent polymer layer. The invention also relates to a laminated packaging material produced by the method and to a packaging container for liquid or semi-liquid food, produced from the laminated packaging material.

A package is provided, comprising a packaging material having a bulk layer and being formed into a three-dimensional container by folding the packaging material along predefined crease lines thus forming a fracture along the crease lines. At least one of the crease lines forms a hinge mechanism having a single axis of rotation.

A sheet of packaging material to form a package, comprises a receiving region to receive an opening device of the package attached thereon, the sheet of packaging material further comprises two reference marks detectable by a detecting unit of an applying device arranged for applying the opening device on the receiving region. A method for producing a package comprises folding, filling and sealing a sheet of packaging material to obtain the package, the packaging material comprising a receiving region to receive an opening device and two reference marks, the method comprising detecting the reference marks and selecting a subsequent action to be performed on the package and/or the opening device on the basis of the detected position of the reference marks.

A paper-based or paperboard-based container (100) for holding a pourable food product is described, the container comprising: a substantially planar bottom portion; a top portion arranged opposite the bottom portion and comprising a top panel and a top sealing region (126) forming a top seal of the container; and a wall portion extending between the bottom portion and the top portion and comprising a plurality of wall sections (108b, 108c) bordering the top panel and a longitudinal sealing band (14) extending between the bottom portion and the top portion and over at least one of the wall sections, wherein the top sealing region is folded onto said at least one of the wall sections comprising the longitudinal sealing band (14) and being attached thereto. A blank and a sleeve for producing the container is also described, as is a method for producing the container.

A paper container includes a body front panel (5), a body left side panel (6), a body right side panel (8), and a body back panel (7), which are contiguous through body vertical folding lines. A vertical direction sealing panel (25) is configured to form a quadrangular tubular body (26). A top portion (28) has an inclined surface (S) which is lower on the body front panel side and higher on the body back panel side. The inclined surface has an opening, and a spout is provided at the opening. The body vertical folding line through which the body front panel and the body right side panel are contiguous with each other and the body vertical folding line through which the body front panel and the body left side panel are contiguous with each other are approximately symmetrical bent lines bent toward a center of the body front panel.

A sheet packaging material includes fold lines along which the sheet packaging material is foldable to form a sealed package containing a pourable food product. The packaging material comprises at least one base layer that imparts stiffness, at least one lamination layer applied to and covering the base layer; and a removable portion which, in use, is partly detachable from a remainder of the sheet packaging material and foldable at a folding zone to free a pour opening by which to pour the food product from the package. The removable portion comprises at least one aperture formed at least in the base layer and covered by a cover material, and the removable portion is crossed by one of the fold lines defining in use an edge between two walls of the package.

A spray retort system includes a vessel having an interior and a load defined by at least one paperboard container. The at least one paperboard container comprises a body having a top end, a bottom end, and an exposed edge, and the load is positionable within the interior of the vessel. The system further includes at least one nozzle positioned within a top interior portion of the vessel to spray processing fluid onto a top of the load and a first supplemental nozzle arranged on the top interior portion of the vessel to spray processing fluid downwardly along the exposed edge of the at least one paperboard container.
