A packaging material is provided, comprising a core material layer and at least one polymer layer being laminated thereto. The core material layer is provided with at least one area being configured to assist in folding the packaging material into a bottom end corner of a package to be formed, wherein the packaging material comprises a first set of crease lines being designed to form a bottom end of the package, and a second set of crease lines being designed to form a main body of the package. The at least one area comprises an intersection of a plurality of crease lines, each having a triangular cross-section, while a plurality of crease lines of the first set of crease lines, each having a triangular cross-section and having a virtual extension through the intersection, are terminated such that they end at a distance from the intersection.

Method for producing a packaging material

A sheet packaging material for producing a sealed package comprises two first boundary edges parallel to a longitudinal direction and two second boundary edges parallel to a transversal direction orthogonal to the longitudinal direction. The sheet packaging material includes at least a bottom transversal crease line including a bottom central portion, a bottom end portion and a bottom side portion. The sheet packaging material includes a pair of slanted crease lines inclined relative to both the longitudinal and transverse directions. The slanted crease lines have first ends pointing to one of the second boundary edges and second ends pointing to a continuous line parallel to the transversal direction and including the bottom central portion and the bottom end portion. The slanted crease lines delimit, with the bottom side portion, a flap area of the sheet packaging material designed to form at least part of a lateral flap of the package.
