Zusammenfassung:The present invention is related to a heat sealable coextruded multilayer packaging film peelable on a variety of substrates including polyethylene, polypropylene, polyester, polyvinyl chloride, polyamide, polyacrylonitirle and paper, comprising at least one peelable layer from a pre-compounded precursor formulation containing: -50 to 80% by weight of an ethylene homo and/or copolymer, -15 to 25% by weight of a styrene homo or/and copolymer, -5 to 20% by weight of a thermoplastic elastomeric styrene-butadiene-styrene block copolymer, characterised in that the peel force in said peelable seal film produced by said pre-compounded precursor is modified by the presence in said precursor in the final extrusion step of 5 to 25, and preferably 10 to 20% by weight of homogeneously branched LLDPE and/or polybutene-1.
