Abstract: A sheet packaging material for producing a sealed package with a pourable food product; the packaging material has a quadrangular configuration with two boundary edges parallel to a longitudinal direction and two other boundary edges parallel to a transversal direction orthogonal to the longitudinal direction; the packaging material comprises two transversal crease lines extending transversally to the longitudinal direction and dividing the packaging material into: a bottom region containing a bottom crease pattern and configured to form a bottom portion of the package; a top region containing a top crease pattern and configured to form a top portion of the package; and an intermediate region contained between the transversal crease lines and designed to form a main portion of the package having a plurality of side wall portions; the intermediate region further comprises a plurality of V-shaped crease lines having respective vertices located on or adjacent to the transversal crease lines and at given points t

Abstract: A sealed package containing a pourable food product and comprising a bottom portion, a top portion and a main portion interposed between the bottom portion and top portion and including a plurality of side wall portions; the main portion is divided from the bottom portion and said top portion respectively by a bottom peripheral outline and a top peripheral outline extending transversally with respect to a longitudinal direction; each of the bottom peripheral outline and the top peripheral outline has a broken-line shape and is formed by a plurality of contour edges joined to each other; the bottom portion comprises a quadrilateral bottom panel delimited by the bottom peripheral outline and extending orthogonal to the longitudinal direction; the top portion comprises a quadrilateral top panel delimited by the top peripheral outline and extending transversally to the longitudinal direction; the area of the bottom panel is different from the area of a top quadrilateral obtained by projecting, along the longitudi
