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 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,
a sleeve surface, wherein the sleeve surface comprises a front surface, a first side surface, a second side surface, a first rear surface and 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 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.
