A process for the hermetic sealing of containers, characterized essentially by starting from a sheet formed by a sheet of paper, one of whose faces is provided with a regularly distributed and firmly attached layer, of a thermoplastic material, proceeding to the separation of said sheet. laminated piece by die-cutting, of the individual seals that are subsequently applied on the neck edge of the container to be sealed, so that the thermoplastic material-coated area coincides with the edge of the container, the heat application being carried out in a direct way on the sheet of paper, avoiding the local action of the heat on the layer of thermoplastic material and providing sufficient mechanical rigidity for the correct separation of the seal at the opening of the container.
