Abstract
The present invention concerns a multi-layer film comprising at least five layers, with two outer layers, two intermediate layers and one core layer, wherein the core layer comprises an ethylene copolymer having a density between ≥0.910 g/cm3 and 0.925 g/cm3, the intermediate layers comprise an ethylene copolymer comprising 1-octene and having a density between >0.915 g/cm3 and 0.925 g/cm, wherein further the first outer layer comprises between 65 wt. % and 93 wt. % of a first ethylene copolymer comprising 1-octene and having a density between >0.915 g/cm3 and 0.925 g/cmand between 7 wt. % and 35 wt. % of a second ethylene copolymer having a density between >0.925 g/cmand 0.945 g/cm3 based on the total weight of polymers of the layer, wherein further the second outer layer comprises between 35 wt. % and 65 wt. % of a first ethylene copolymer comprising 1-octene and having a density between >0.915 g/cmand 0.925 g/cmand between 35 wt. % and 65 wt. % of a second ethylene copolymer having a density between 0.850 g/cmand <0.915 g/cmbased on the total weight of the polymers of the layer.
