Abstract
Multilayer film which comprises a core layer (C) and two outer layers (0-1, 0-2) sandwiching the core layer, wherein (i) the core layer (C) comprises 90 to 100% by weight of a first bimodal ethylene/1-butene/C6-C12-alpha-olefin terpolymer having a density between >925 kg/m3 and 970 kg/m3 with respect to the total weight of the layer, (ii) two outer layers (0-1) and (0-2) comprise (ii-1) the bimodal terpolymer as defined for the core layer (C) and (ii-2) a second bimodal ethylene/1-butene/C6-C12-alpha-olefin terpolymer having a density between >910 kg/m3 and <925 kg/m3.
Claims20
A multilayer film comprising a core layer (C) and two outer layers (O-1, O-2) sandwiching the core layer, wherein
- (i) the core layer (C) comprises from 90 to 100% by weight of a first bimodal ethylene/1-butene/C6-C12-alpha-olefin terpolymer having a density between >925 kg/m3 and 970 kg/m3 with respect to the total weight of the layer,
- (ii) the two outer layers (O-1) and (O-2) each comprise a blend of
- (ii-1) the first bimodal terpolymer as defined for the core layer (C) and
- (ii-2) a second bimodal ethylene/1-butene/C6-C12-alpha-olefin terpolymer having a density between >910 kg/m3 and <925 kg/m3.
