Abstract

A polyolefin film which may take the form of a coating on paper has adhered thereto a heat-sealable layer of a polyolefin with a lower melting point than that of the polyolefin film. The film is prepared by applying the layer to or forming the layer on at least one surface of the film e.g. by the application thereto of the lower melting point polyolefin as a solution in a solvent, an aqueous dispersion which is thereafter heated to provide a coating of between 0,2 and 4,0 gm. per square metre, a hot melt the temperature of which may be greater than its gelation temperature, or as a fine dry powder which is thereafter fused. The layer of lower melting point polyolefin may be applied to one surface of the film and thereafter compression rolled. The compression rolling may be sufficient to reduce the thickness of the film to between one-half and one-tenth of its original thickness. The polyolefins may be polymers or copolymers of a -olefins having between 2 and 10 carbon atoms e.g. ethylene or propylene, degraded polyethylene or oxidized degraded polyethylene, and may contain a thermosetting resin such as phenol-formaldehyde. The coatings may be applied, for example, by dipping, kiss-roll, air knife or spreader-bar. The surface of the low melting point polyolefin which remains exposed may be subjected to a corona discharge or flame treatment to improve the surface for printing, or subsequent coating with photographic gelatin emulsions or emulsions of metal oxides in the production of magnetic tapes.
