A landfill with perfected seal, which is essentially characterized by having its upper edge slightly remelted and bent inward on itself, forming on the edge of the fold a horizontal flange of very little width, on which the seal is retained when entering under pressure in the landfill and said seal being constituted by a circular sheet embedded in a flange around its edge, vertical and folded on itself, in such a way that when entering the seal with the flange downwards, in the opening of the dump, it does so under pressure acting said tab as a laminar spring and once the seal is entered it is impossible to remove it without destroying it.
