Packaging film comprising a sealing layer and a substrate

摘要

A packaging film containing a) a heat-sealable layer comprising a mixture of from 50 to 80% by weight of a random terpolymer (I) comprising from 90 to 97% by weight of propylene, from 2 to 6% by weight of ethylene and from 1 to 6% by weight of a C4- to C10-alk-1-ene, and from 20 to 50% by weight of at least one ethylene polymer (II),and b) a base layer (support layer) of a thermoplastic polymer. The packaging film according to the invention is distinguished, in particular, by easy heat-sealability over a broad temperature range.
