Abstract: The invention concerns a fibrous-based oxygen barrier film, which comprises (i) a microfibrillated cellulose (MFC) film, (ii) an oxygen barrier polymer layer, (iii) an optional tie layer, and (iv) an outermost polyolefin layer. The invention even concerns a laminate, in which said multilayer film is combined with a fibrous paper or board base by means of an intermediate poly-ethylene layer. The oxygen barrier polymerlayer, which preferably is EVOH, and the polyolefin layer are brought by coextrusion onto the MFC film. The film and the laminate according to the invention aim at an improved oxygen barrier in high humidity conditions and have use in oxygen-sensitive food packaging.
