It comprises at least one longitudinal weld (3) linking the ends of said sheet, at least one internal welding strip (11) situated inside the packaging to form said longitudinal weld (3), the internal strip (11) comprising a sealing material which becomes liquid during the welding of the ends and fills cavities (13) formed at the ends of the internal strip (11) so that the packaging is leak-proof once welded.
