Abstract: A multi-layer packaging film is provided having at least four layers arranged in sequence comprising: (1) a heat-sealing first layer comprising at least 50% by weight of a copolymer of propene, and at least one ?-olefin selected from the group consisting of ethylene, butene-1, methylpentene-1, hexene-1, octene-1, decene-1 and mixtures thereof, said copolymer having a propene content of at least 60 wt. %, a Tm between about 100° C. and about 145° C., a Mw/Mn of between 1 and 5, and n-hexane extractables of less than 4 wt. %; (2) second and fourth layers each comprising (a) at least 10 wt. % of a first copolymer of ethylene and at least one C4-C8 ?-olefin, said copolymer having a density of from 0.900 to 0.915 g/cm3 and a melt index of less than 2 dg/min., (b) at least 10 wt. % of a second copolymer of ethylene with from 4 to 18 wt. % of a vinyl ester, alkyl acrylate, acrylic or methacrylic acid, and (c) from 0 to 60 wt.
