ABSTRACT The invention relates to a heat sealable at least mono- axially orientated multilayer film consisting of a propylene polymer as the base layer, on at least one surface of which a layer combination is arranged which from the outside towards the base layer, is composed of A) a heat sealable outer layer of (a) 66.5 to 94.5% by weight of a linear statistical ethylene copolymer with a low density (LLDPE), (b) 5 to 30% by weight of a low molecular weight resin which is compatible with the LLDPE, with the exception of a low molecular weight resin of .alpha.-olefins having at most 3 C-atoms, (c) 0.3 to 2% by weight of a mixture of a polyethylene wax and an oxazoline wax, and (d) 0.2 to 1.5% by weight of a polydiorgano-siloxane wherein the sum of components a) to d) is 100% by weight, C) an adhesion layer containing modified polyolefin, D) a gas-barrier layer based on a saponified ethylene vinyl acetate copolymer containing 40 to 85 mol% of vinyl acetate units which are saponified to an extent of at least 90%, E) an adhesion layer containing a modified polyolefin. The film, owing to its gas-barrier properties, is particularly suitable for packaging products which require low gas permeability and aroma protection.
