Claim:
Packaging material configured to be folded and sealed to produce a gable-top package for pourable food products which possesses top and bottom portions, the packaging material comprising: a web of material provided with a crease pattern along which the web of material is foldable to form the gable-top package; the crease pattern on the web of packaging material comprising: a first transverse fold line extending transversely across the web of material between one longitudinally extending side edge of the web of material and an opposite longitudinally extending side edge of the web of material; a second transverse fold line extending transversely across the web of material between the one longitudinally extending side edge of the web of material and the opposite longitudinally extending side edge of the web of material; the second transverse fold line being positioned at one longitudinal end of the web of material and defining a top sealing area at which the web of material is sealed when the packaging material is folded and sealed to form the top portion of the gable-top package; the first transverse fold line being spaced from the second transverse fold line in a direction toward an opposite longitudinal end of the web of material; a plurality of longitudinal fold lines extending longitudinally away from the first transverse fold line toward the opposite longitudinal end of the web of material, with adjacent pairs of the longitudinal fold lines defining respective walls of the gable-top package when the packaging material is folded and sealed; a pair of oblique fold lines each extending obliquely from the first transverse fold line to the second transverse fold line such that an area is bounded by the pair of oblique fold lines, by a portion of the second transverse fold line extending between the pair of oblique fold lines and by a portion of the first transverse fold line extending between the pair of oblique fold lines; the area enclosing six, and no more than six, triangular panels, each of the triangular panels being outlined by three fold lines forming a part of the crease pattern; and three of the six triangular panels together forming an isosceles triangle, the isosceles triangle being defined by three of the fold lines forming a part of the crease pattern.
