摘要： There is described a packaging blank (2) comprising a first longitudinal boundary edge (8), a second longitudinal boundary edge (9), a first transversal boundary edge (10) and a second transversal boundary edge (11). The packaging blank also comprises a top crease pattern (4) having a first transversal crease line (15) and a second transversal crease line (16) and a bottom crease pattern (5) having a third transversal crease line (17) and a fourth transversal crease line (18). The second transversal crease line (16) is closer to the first longitudinal boundary edge (8) and/or to the second longitudinal boundary edge (8) than the first transversal crease line (15) and/or the fourth transversal crease line (18) is closer to the first longitudinal boundary edge (8) and/or the second longitudinal boundary edge (9) than the third transversal crease line (17).

摘要： A packaging material (100) is provided, comprising a core material layer (140) and at least one polymer layer (142, 145, 147) being laminated thereto. The core material layer (140) is provided with at least one area (C1, C2, C3, C4) being configured to assist in folding the packaging material (100) into a bottom end corner (PC1, PC2, PC3, PC4) of a package (10) to be formed, wherein the packaging material (100) comprises a first set of crease lines (132) being designed to form a bottom end (BP) of the package (10), and a second set of crease lines (134) being designed to form a main body (MB) of the package (10). The at least one area (C1, C2, C3, C4) comprises an intersection (IX) of a plurality of crease lines (BC, LCB), each having a triangular cross-section, while a plurality of crease lines (LCC, DC, BC') of the first set of crease lines (132), each having a triangular cross-section and having a virtual extension through said intersection (IX), are terminated such that they end at a distance (D) from said intersection (IX).
