Abstract (en)

[origin: WO2014173423A1] The present invention relates to a multilayer film comprising a layer sequence made of (a) a layer (a) composed of at least one polyethylene of low density in the range from 0.915 to 0.935 g/cm3 or of a mixture of (α) at least one polyethylene of relatively low density in the range from 0.915 to 0.935 g/cm3 and of (β) at least one aliphatic C3-C6 olefin homo- or copolymer, (b) a layer (b) composed of a mixture of I at least one polyethylene of low density in the range from 0.915 to 0.935 g/cm3 and II of at least one thermoplastic polymer selected from the group comprising polystyrenes and styrene copolymers, (c) a layer (c) composed of at least one polyethylene of low density in the range from 0.915 to 0.935 g/cm3 or of a mixture of (α) at least one polyethlene of low density in the range from 0.915 to 0.935 g/cm3 and of (β) at least one aliphatic C3-C6 olefin homo- or copolymer, where the tear propagation force of the multilayer film both in machine direction and perpendicularly to machine direction is at most 1000 mN, determined for a total film thickness of 50 μm in the Elmendorf test in accordance with DIN EN ISO 6383-2.
