<p>A sealing assembly (S) for a container (C) with an opening (O), including a sheet (F) welded to the edge of the opening and consisting of at least three layers, i.e. a weld layer (1) applied and welded to the edge of the opening along a bead (4), an outer barrier layer (2) and an intermediate adhesive layer (3). The weld between the bead (4) of the weld layer (1) and the edge of the opening has a tear resistance higher than the adhesive force between the weld layer (1) and the adhesive layer (3), whereby after the opening (O) has been unsealed for the first time, the weld bead (4) remains in place along the edge thereof and is separated from the weld layer (1) and the adhesive layer (3), which is thus exposed in an area (7) and enables the container (C) to be resealed by reapplying said layer onto the bead (4).</p> |
