Shown and described are a packaging machine and a method for producing a packaging unit from a packaging sleeve group comprising a plurality of flat folded, upright packaging sleeves, and an outer packaging. It is provided that the packaging machine comprises at least one conveyer unit for conveying the packaging sleeve group in a conveyor direction perpendicular to the longitudinal extent of the packaging group and at least one outer packaging unit for preparing an outer packaging-shaping sheet material in a base position, and in that, seen in the conveyor direction behind the sheet material in the base position, a sealing unit is provided for sealing of the sheet material enclosed in the packaging sleeve group.

The invention relates to a method comprising, as method steps, a) providing a sheetlike composite comprising, as mutually superposed layers of a layer sequence, from an inner face of the sheet like composite to an outer face of the sheetlike composite i) an inner polymer layer, ii) a barrier layer, and iii) a carrier layer, wherein the sheetlike composite comprises a first longitudinal edge and a further longitudinal edge, wherein the first longitudinal edge lies opposite the further longitudinal edge, wherein the sheetlike composite includes, in the following sequence in the direction from the first longitudinal edge to the further longitudinal edge: i.a first longitudinal g crease, ii.a second longitudinal crease, iii.a third longitudinal crease, and iv.a fourth longitudinal crease; b) producing a first longitudinal fold characterized by a first internal angle along the first longitudinal crease and a third longitudinal fold characterized by a third internal angle along the third longitudinal crease; c) producing a second longitudinal fold characterized by a second internal angle along the second longitudinal crease and a fourth longitudinal fold characterized by a fourth internal angle along the fourth longitudinal crease; and d) contacting and joining the first longitudinal edge to the further longitudinal edge thereby obtaining a longitudinal seam. The invention further relates to a container precursor and to a closed container, each obtainable by the method, to an apparatus and to a use of the apparatus.
