A multilayer film is described which comprises a base layer of a propylene polymer and at least one heat-sealable layer of a combination of a) from 67.5 to 89.6 % by weight, based on the heat-sealable layer, of an olefin resin composition comprising a copolymer or terpolymer of ethylene, propylene, butylene or further alpha -olefins having 5 to 10 carbon atoms, or mixtures thereof b) 5 to 15 % by weight, based on the heat-sealable layer, of a low-molecular-weight resin which is compatible with the olefin resin composition, c)from 5 to 15 % by weight, based on the heat-sealable layer, of a propylene homopolymer, d)from 0.3 to 1.5 % by weight, based on the heat-sealable layer, of a polydiorganosiloxane and e) from 0.1 to 1.0 % by weight, based on the heat-sealable layer, of a silicate having a leaf-like structure. m |
