Abstract: Process for manufacturing metallic strip for packaging comprising strip steel covered on at least one of its faces with a coating containing a sub-layer of tin and an external film of polymer, according to which: on one hand, a layer of tin is deposited on at least one of the faces of the steel strip; and on the other, a layer of tin is vacuum-deposited on one face of at least one polymer film; then at least one polymer film covered with tin and the steel strip having at least one layer of tin are brought together in such a way that the face of at least one film of polymer covered with tin or tin base alloy will be across from one face of the steel strip having a layer of tin and injecting a flux between the said faces to clean the surfaces covered with tin; and at least one polymer film is welded on the face of the steel strip.

Abstract: A treatment process for metal in which there is applied to a metal surface a film of an organic product, the film is heated to a suitable temperature for a suitable time so that all or a portion of the product becomes fixed on the metal surface and the organic product becomes partly cross-linked on the surface. Applications to corrosion protection, to lubrication and to preparation for coating, especially varnishing sheets.
