Heat-sealable seal including a support bonded to an inner seal by a temporary adhesive is provided. The inner seal has a pull-tab which is folded back once on the surface of the inner seal in contact with the corresponding surface of the support. The inner seal includes a laminate having a reinforcing layer and a sheet of a conducting material, to the lower surface of which is applied a heat-sealing film. The temporary adhesive is applied to the whole surface of the inner seal once the pull-tab is folded back. The seal is characterized in that the laminate has over its entire thickness a notch from which the pull-tab emerges, and a fold line formed by the pull-tab once the pull-tab is folded back, the fold line having a shorter length than the length of the notch. Methods of producing the seal are also disclosed.
