Zusammenfassung:	A method is described for joining a first sheet (110) and a second sheet (120) of packaging material, which comprises: preparing the first sheet (110) with a first joint edge (111) transverse to a longitudinal axis (Y1) of the first sheet, and having a particular configuration with a non-straight edge; arranging the second sheet (120) with a second joint edge (121) transverse to a longitudinal axis (Y2) of the second sheet; superimposing the first and second joint edges (111, 121) to join the first and second sheets (110, 120) so that the longitudinal axes (Y1, Y2) are aligned, and the second sheet (120) constitutes a continuation of the first sheet (110) along the longitudinal axes; welding together the first and second joint edges (111, 121) superimposed on each other.
