Packaging material for the formation of a packaging container, including a top side, the packaging material bounded by a first edge and second edge opposite the first edge, and the packaging material comprising at least:
- a base layer configured to provide stiffness and strength and having a hole,
- a first cover layer,
- a second cover layer,
- a gas- and light-barrier layer comprising a gas- and light-barrier material,
- a further cover layer, being interposed between the gas- and light-barrier layer and the base layer, and
- at least one separation element covering the hole, wherein the separation element is formed from a portion of the first cover layer and/or of the second cover layer and/or of the light-barrier layer and/or of the further cover layer;
- wherein the hole extends within a plane being defined by a longitudinal axis and a transversal axis orthogonal to the longitudinal axis;
- wherein the hole is arranged in an area forming the top side packaging container, the area being delimited by:
- two transverse crease lines parallel to the transversal axis comprising a first transverse crease line and a second transverse crease line;
- and
- two longitudinal crease lines parallel to the longitudinal axis comprising a first longitudinal crease line and a second longitudinal crease line;
- wherein the second longitudinal crease line forms a front edge of the top side;
- wherein the first longitudinal crease line is parallel to the first edge of the packaging material;
- wherein the packaging material is configured to be sealed to form the top side of the packaging container by binding together as a seam the packaging material between the first edge and the first longitudinal crease line;
- wherein the first longitudinal crease line is located between the hole and the first longitudinal edge, such that the hole located apart from the seam;
- wherein an imaginary longitudinal line parallel to the longitudinal axis and an imaginary transversal line parallel to the transversal axis mutually intersect at a respective center point of the hole;
- wherein a first maximum extension of the hole along the imaginary longitudinal line is larger than a second maximum extension of the hole along the imaginary transversal line;
- wherein the hole has an asymmetric shape with respect to the imaginary transversal line,
- wherein the packaging material comprises a plurality of crease lines along which, in use, the packaging material is folded, and
- wherein the first maximum extension ranges between 30 mm to 45 mm and the second maximum extension ranges between 10 mm and 20 mm and in that the hole is arranged in an area delimited by two crease lines parallel to the longitudinal axis and two crease lines parallel to the transversal axis.
