Abstract

Process for producing coated papers and coated cardboards endowed with properties of barrier against the migration of water vapour, which consists in generating on the surface of paper and/or cardboard, at least one layer based on vinyl polymers and/or copolymers, in submitting the surface of the so-treated paper and/or cardboard to a suitable surface treatment for modifying its structure and for rendering said surface wettable by water-based dispersions, preferably consisting in submitting said surface to a corona-­ effect electrical discharge, and in generating at least one further layer by means of the spreading of conventional coating substances, with a layer of "pre-­ coat" being possibly interposed between bare cardboard and sad polymer-based layer.
Coated papers and cardboards with barrier properties obtained by means of said process.
