<p>A description follows of a film with a high thickness coating, consisting of a thermoplastic base, wherein the high thickness coating comprises a first layer made up of a primer in dispersion, suspension or aqueous emulsion and at least one subsequent homogeneous layer of a PVDC (polyvinylidene-chloride) copolymer, wherein said at least one homogeneous layer of PVDC (polyvinylidene-chloride) copolymer is present in a quantity of at least 20 g/m<2>. The main advantage of this product is that it has extremely reduced diffusional properties with respect to water vapour, gases and aromas, and is therefore a product with optimum barrier properties, an excellent quality for the production of blister-type packaging, for example. <IMAGE></p> |
