METHOD OF PRODUCING A PACKAGING MEANS ENVELOPING CONTAINER PRECURSORS, ESPECIALLY EACH FOR A SINGLE DIMENSIONALLY STABLE FOODSTUFF CONTAINER, WITH FOLDING OVER OF THE CONTAINER PRECURSOR

The invention relates to a method comprising, as method steps, A) providing a multitude of container precursors, in each case comprising: a) providing a sheetlike composite, wherein the sheetlike composite comprises a first longitudinal edge, a further longitudinal edge and, from the first longitudinal edge to the further longitudinal edge: i. a first longitudinal 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; d) contacting and joining the first longitudinal edge to the further longitudinal edge thereby obtaining a longitudinal seam; and e) reducing the first internal angle and the third internal angle each to not more than 15° and increasing the second internal angle and the fourth internal angle each to at least 165°; and B) enveloping the multitude of container precursors with a packaging means. The invention further relates to a packaging means obtainable by the method, to an apparatus and to a use of the apparatus.
