<p>The invention concerns a composition comprising (by weight): 55 to 99.5 parts of EVOH copolymer; 0.5 to 45 parts of polypropylene (A) and compatibilising agent (B), the proportions of (A) and (B) being such that (A)/(B) ranges between 1 and 5; the ratio of the MFI of EVOH over the MFI of polypropylene is higher that 5, MFI representing the melt flow index. Said composition is useful for making barrier films, in particular for oxygen, used in packaging.</p> |
