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 method for precursor production includes A) providing a multitude of container precursors, and in each case a) providing a sheet-like composite, having a first longitudinal edge, a further longitudinal edge and, from the first longitudinal edge to the further longitudinal edge: i. a first longitudinal crease, ii. a second longitudinal crease, iii. a third longitudinal crease, and iv. a fourth longitudinal crease. The method includes b) producing a first longitudinal fold characterized by a first internal angle along the first longitudinal crease and a third longitudinal fold characterized by a third internal angle along the third longitudinal crease; c) producing a second longitudinal fold characterized by a second internal angle along the second longitudinal crease and a fourth longitudinal fold characterized by a fourth internal angle along the fourth longitudinal crease; d) contacting and joining the first longitudinal edge to the further longitudinal edge thereby obtaining a longitudinal seam.
