Abstract

In a thermoplastic multi-layer packaging film comprising (a) an outer polymer layer, (b) an inner heat sealing layer, and opt. (c) an intermediate O2 barrier layer, the heat-sealing layer (b) comprises a copolymer of ethylene and x to y wt.%, w.r.t. the copolymer, of a 4-8C alpha-olefin, with the copolymer having a density of less than 920 kg/cubic m. x=0.5 nC+8; y=1.25nC+15; nc=a number of C in the alpha-olefin.
