Abstract: A multi-layer sheet designed for the sealing of a container (10) made of glass by heat sealing on the sealing ring (12) of the container treated by means of oxides and/or of metal salts comprises at least a support layer (21) and a lower layer (22) made of a polymeric heat-sealable material onto which is grafted an unsaturated carboxylic acid.

Abstract: A sealing product to be sealed on at least one ring-shaped sealing zone which surrounds the opening of a container, made from a sealing sheet including a support layer of a fibrous material of mainly vegetable fibers and a multi-layer structure including, on one of its faces, an adhesive layer and, on its other face, a sealing layer, whereby the sealing product is stamped to make a relief whose form is such that its base follows, at least discontinuously, a contour close to that of the internal edge of the ring-shaped sealing zone, the structure of the sealing sheet including additionally an intermediate layer made of plastic having a good strength, able to undergo plastic deformation, and of which the average thickness is such as it endows the entire sealing product with sufficient malleability and resistance for it to be possible to stamp it to the desired shape without tearing.
