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 thereof destined to define the opposite ends of respective lateral edges delimiting the side wall portions of the package; each V-shaped crease line extending in proximity of the respective transversal crease lines.

Sheet packaging material for producing a sealed package containing a pourable food product and a sealed package obtained from a sheet 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.

Package

A method for producing a sealed package for a product may include: providing a sheet packaging material having a crease pattern with a first transverse crease line, a second transverse crease line, and a plurality of further crease lines interposed between the first and second transverse crease lines, the further crease lines extending transversely to the first and second transverse crease lines; obtaining a sealed preliminary packaging unit from the sheet packaging material, the sealed preliminary packaging unit having a preset inner volume and containing the product; exerting a forming action on the sealed preliminary packaging unit so as to fold the sheet packaging material defining the sealed preliminary packaging unit and obtain a package therefrom. During the step of obtaining the sealed preliminary packaging unit, the sheet packaging material may be processed without being folded along the further crease lines.
