Package for dairy products, sheet, multi-layer film and method associated

Package for dairy products, in particular solid or semi-solid dairy products, comprising:

• a bag (10) provided with at least one pair of lateral walls (11, 12) reciprocally joined by means of first welding lines (16) and second welding lines (19, 20, 19′, 20′), and at least one bottom wall (13), so as to define one housing compartment (35);
• and
• at least one dairy product (P) housed in said compartment (35) defined inside said bag (10),
• wherein the bag (10) comprises said second welding lines (19, 20, 19′, 20′) made in correspondence with top parts (33, 34) of the bag (10) and positioned on opposite sides of said bottom wall (13), said second welding lines (19, 20, 19′, 20′) being disposed diagonally with respect to said first welding lines (16) and with respect to the bottom wall (13) and configured and oriented so as to progressively narrow said housing compartment (35) toward said bottom wall (13) of the bag (10), said dairy product (P) comprising at least a central support zone (Z) on said bottom wall (13), said central support zone (Z) being defined by a rounded surface, such as a circular, oval, elliptical surface, and said bag (10) comprising lateral support zones (Z1, Z2) defined by at least said opposite top parts (33, 34),
• wherein said second welding lines (19, 20, 19′, 20′) are made in welding directions (21, 22, 21′, 22′) that intersect the bottom wall (13) of the package and provide ideal extension lines (37, 38, 37′, 38′) that cross at a point (36, 36′) positioned externally to the bottom wall (13) of the package,
• wherein said bottom wall (13) of the package is made in a single piece with the lateral walls (11, 12) and is recessed toward the inside of the package, so that at least one folding line (28) is created therein;
• wherein said dairy product (P) is at least partly immersed in a preserving liquid;
• wherein the dairy product (P) rests partly on the bottom wall (13) of the bag (10) and at least part of forces generated by a weight of the dairy product and the preserving liquid is discharged onto the second welding lines (19, 20, 19′, 20′), thus allowing a self-stabilization of the package substantially in a vertical position with respect to a support plane O;
• and
• the point (36, 36′) is positioned on a longitudinal axis (L) of symmetry of the bag 10.
