1. A packaging material, comprising:
a core material layer,
at least one polymer layer laminated to the core material layer,
wherein 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,
a first set of crease lines configured to form a bottom end of the package and a first portion of an intersection between the bottom end of the package and a main body of the package, and a second set of crease lines configured to form the main body of the package and a second portion of the intersection between the bottom end of the package and the main body of the package,
said at least one area comprising an intersection of a first plurality of crease lines of the second set of crease lines, each having a triangular cross-section, while a second plurality of crease lines of the first set of crease lines, each having a triangular cross-section and having a virtual extension through said intersection, terminate such that they end at a distance from said intersection and constitute terminated crease lines,
wherein the terminated crease lines of the at least one area comprises one transversal crease line, one longitudinal crease line, and one diagonal crease line.
