<p>The invention relates to the use of a multilayer film for protecting a substrate which gives off volatile compounds which comprises: a surface layer comprising, by weight, from 70 to 100%, preferably from 90 to 100%, of a f luoropolymer and from 0 to 30%, preferably from 0 to 10% of an acrylic polymer ; an adhesive layer comprising from 50 to 100% of an acrylic polymer, from 0 to 50% of a f luoropolymer, from 1 to 10% of a UV stabilizer and from 0 to 50% of an impact modifier, characterized in that the thickness of the surface layer is between 2 and 15 µm, preferably between 2 and 10 µm, more preferably still between 3 and 8 µm, and the thickness of the adhesive layer is between 30 and 75 µm, preferably between 30 and 60 µm, more preferably still between 30 and 50 µm. The invention also relates to a substrate .protected by the multilayer film.</p> |
