1. A flat-shaped composite material for manufacturing a package, comprising:
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,
wherein the flat-shaped composite material has a plurality of fold lines, which are arranged and designed such that a closed package an be manufactured by folding the flat-shaped composite material along the fold lines and by connecting seam surfaces of the flat-shaped composite material,
a sleeve surface, wherein the sleeve surface comprises a front surface, a first side surface, a second side surface, a first rear surface a second rear surface,
base surfaces, wherein the base surfaces comprise triangular base surfaces and quadrangular base surfaces, and
gable surfaces, wherein the gable surfaces comprise triangular gable surfaces and quadrangular gable surfaces,
wherein the base surfaces and the gable surfaces are arranged on opposite sides of the sleeve surface
wherein the sleeve surface has at least one stress-relief surface, which is arranged between the front surface and one of the two side surfaces,
wherein a first sleeve fold line is provided between at least on stress-relief surface and the adjoining front surface, and
wherein a second sleeve fold line is provided between at least one stress-relief surface and the adjoining side surface,
wherein at least one stress-relief surface adjoins a quadrangular base surface in the region of the base surfaces and adjoins a triangular gable surface in the region of the gable surfaces.
