Flat-shaped composite material, package sleeve and package with trapezoidal gable

Abstract

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 and a second rear surface, and base surfaces. The base surfaces include triangular base surfaces and 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. In order to enable the manufacture of packages with even more complex geometries even in the gable and base region, at least one quadrangular gable surface is provided with two small gable surface angles, which are smaller than 90°, with two large gable surface angles, which are greater than 90°, and with an angle sum, which is greater than 360°. 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.
