The invention further relates to a closed container, to a method, to an apparatus and to the use of the container precursor.

The invention relates to a closed container, delimiting an interior from an exterior, wherein the closed container comprises a sheetlike composite; wherein the sheetlike composite comprises a layer sequence, comprising as mutually superposed layers in a direction from an. inner face of the sheetlike composite to an outer face of the sheetlike composite a) an inner polymer layer, b) a barrier layer, and c) a carrier layer; wherein the closed container is characterised by a shaping coefficient, determined according to the method described herein, in the range from 1.0 to 10.0 m.sup.2/kg. Further, the invention relates to a method by which a closed container with a shaping coefficient is obtainable; to the closed container obtainable by this method; to an apparatus, designed for producing one of the afore mentioned closed containers; to a use of a sheetlike composite for producing one of the afore mentioned closed containers; and to a use of one of the aforementioned closed containers for storing a foodstuff.

Package material comprises one or more layers of plastic laminate, a first side, a second side and an penetration area (40). Two weakening lines (30, 30b) extend from the penetration area (40) creating a space in between and thus forming an opening ( ) in the package material. The package material comprises a plastic opening device ( ), with a first and second portion ( ) attached to the first and second side, respectively and a material bridge ( ) penetrating through the penetration area (40). The second portion covers at least partly the penetration area and comprises a guiding portion ( ) extending from the penetration area (40) onto the space adjacent and to the weakening lines (30, 30b) as to facilitate rupturing substantially along the at least one weakening line.

A package material comprises a multilayer material structure with layers of plastic laminate, a penetration area (5, 62, 250) and two weakening lines (10) creating an area in between. The package material comprises an opening device with a first (3, 63, 220) and second (2, 222) portion attached to respective sides and a material bridge (31, 65, 231) penetrating the penetration area and connecting the first portion to the second portion. The second portion at least partly covers the penetration area and comprising a rupture section (13, 213) covering at least partly the two weakening lines. The rupture section comprises one or more rupture recesses (14, 141-145, 232) disposed over or adjacent to the weakening lines for guiding a rupture of the multilayer material structure along the weakening lines.

A package material blank comprises a body panel having a main panel, two second panels arranged adjacent to the main panel and at least one third panel. End closure panels arranged adjacent to the body panel, the end closure panels comprising a top and bottom closure panels arranged adjacent to the main and the at least one third panel, respectively and flap closure panels arranged adjacent to the two second panels. Lines of weakness separate each of the body and end closure panels. A line of weakness is provided on the main panel having a first portion and a second portion, wherein the first portion extends from a first point to a second point and the second portion extend from a third point to the second point.

The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer of paper, paperboard or other cellulose-based material, an innermost, heat sealable and liquid-tight layer of a thermoplastic polymer, the innermost polymer layer intended to be in direct contact with the packaged food product, a barrier layer laminated between the bulk layer and the innermost layer. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.
