Abstract
The cellulose-based packaging includes a tubular body obtained by welding or bonding a sheet, including at least one longitudinal weld linking the ends of said sheet, at least one internal welding strip situated inside the packaging to form the longitudinal weld, the internal strip including a sealing material which becomes liquid during the welding of the ends and fills cavities formed at the ends of the internal strip so that the packaging is leak-proof once welded.
