Abstract: A packaging film suitable for an outer packaging composed of an optionally release-capable, upstretched, at least monolaminar polyolefin film comprising a) a layer (a) based on a mixture of ?) 20-49% by weight of a polypropylene or of at least one propylene copolymer, or combination thereof, and of ?) 80-51% by weight of at least one polyethylene or ethylene copolymer, and optionally ?) customary auxiliaries, with a layer thickness of ?20 ?m, on at least one surface of the layer (a) a release coating (b) composed of cured polysiloxane, wherein the tensile strength of the polyolefin film in machine direction is at least 6.5 N/cm, measured according to DIN EN ISO 527-3, and outer packagings produced therefrom.

Abstract: Multilayer polyolefin film comprising a layer sequence of a sealable layer (a) based on a polyethylene component, a layer (b) based on a polymer mixture of 51-85 wt. % of at least one polyethylene and 15-49 wt. % of at least one propylene homopolymer or copolymer and a sealable layer (c) based on a polyethylene component, wherein the melting point of the layer (a) or the layer (c) is at least 5° C. lower than the melting point of the layer (b); the tear propagation capability of the polyolefin film in the machine direction is <5 N, and the tear propagation capability transverse to the machine direction is at least four times higher than in the machine direction, and the tensile strength is >15 N approximately equal manner in machine direction as well as transversally to the machine direction.
