Abstract
A method for precursor production includes A) providing a multitude of container precursors, and in each case a) providing a sheet-like composite, having 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. The method includes 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.
