A flat-shaped composite material is represented and described for manufacturing a package, including: a polymer outer layer, a polymer inner layer, a fibrous support layer, which is arranged between the polymer outer layer and the polymer inner layer. 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.

A package made of a composite material is represented and described, including: a package base with two front base corners and with two rear base corners, a package gable with two front gable corners and with two rear gable corners, and a package base body with a front panel, a first side panel, a second side panel and a rear panel. The package base and the package gable are arranged on opposite sides of the package base body. The composite material has a polymer inner layer, a polymer outer layer and a fibrous support layer, which is arranged between the polymer outer layer and the polymer inner layer. In order to enable the manufacture of packages with even more complex geometries without impairing the rigidity of the package, it is proposed that the package base body has at least one stress-relief panel, which is arranged between the front panel and one of the two side panels.

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.

There is described a pre-creased sheet packaging material for forming a sealed package comprising: a plurality of longitudinal crease lines, which extend along a longitudinal direction; a plurality of transversal crease lines, which extend along a transversal direction; at least one first additional crease line, which extends along a further direction, which is slanted with respect to longitudinal direction and transversal direction; a first joining point, at which longitudinal crease line and a transversal crease line join with respect to one another; and at least one first area, which is bounded by longitudinal crease line, transversal crease line and additional crease line; further direction being incident to first longitudinal crease line and to first transversal crease line in first joining point; at least one of first longitudinal crease line, first transversal crease line and first additional crease line being interrupted at first joining point.

A sheet packaging material for producing a sealed package containing a food product, comprising crease lines that have sections that are angled towards each other such that at least two sides panels of the sealed package are given a trapezoidal shape.

A composite package, in particular a beverage carton package for liquid foodstuffs is depicted and described which consists at least partially of a package laminate, having a package base body including package edges, an at least partially angular package base and package gable wherein the package base body defines, in an idealised manner, a package front side, package rear side and at least two lateral package sides attaching to the package rear side as well as a package laminate and a package sleeve blank for manufacturing such a composite package. In order to improve grip and ergonomy for an easy to manufacture package, provision is made for the package front side to have a positive arching at least in sections which in each case passes into a lateral package side for a grip panel to be formed at least in sections in the region of the package rear side.

A paper container having a top portion (4) that is tightly closed by bonding together opposing surfaces of first top sealing panels (20) and opposing surfaces of second top sealing panels (22), and each of side panels (16) is folded along a first side panel folding line (26) and a second side panel folding line (27) to form a flap (35) having a substantially triangular shape. The top portion (4) is formed by folding down the flaps (35) onto right and left side surfaces of a tubular body (3) through mountain-folding along front-side top panel vertical folding lines (17), front-side top panel vertical folding lines (18), and front-side top sealing vertical folding lines (23), and through valley-folding along second top portion horizontal folding lines (15) and back-side top sealing vertical folding lines (24).
