<p>This invention relates to a co-extruded multilayer film and particularly for vacuum packaging food products. The film comprises at least one layer formed by an ethylene-vinyl acetate-copolymer with a vinyl acetate content preferably comprised between 9% and 26% range by weight. The film is preferably radiated at a lower level than 20 MRad. The film is adapted to resist high stretch ratios during the packaging proces, so that packaging of bodies with projecting portions or cavities is possible, without breaking the film.</p> |
