The invention relates to a method for producing a laminar product suitable for manufacturing external covers of sanitary towels and nappies, formed by a polymeric coating deposited over the surface of a non-woven fabric substrate, as well as to the laminar product obtained using said method. The method comprises the following steps: obtaining adhesive polymeric mixtures, feeding the mixtures, in a melted state, to a curtain-type applicator, coating the substrate with the adhesive polymeric mixtures, and winding the laminar product obtained. The product obtained comprises a polymeric coating bonded to the non-woven fabric substrate, wherein the polymeric coating consists of an adhesive polymeric layer that has a reduced thickness, ranging between 1 and 10 micra, said product being suitable for medical and personal hygiene applications.
