| description | The present invention relates to a multimodal ethylene copolymer composition comprising 5 to 25 wt.%, relative to the total weight of the multimodal ethylene copolymer composition, of a first ethylene copolymer (A1) comprising a copolymer of ethylene and at least a first α-olefin comonomer, with a density as determined according to ISO 1183-187 ranging from 920 to 960 kg/m3; 15 to 35 wt.%, relative to the total weight of the multimodal ethylene copolymer composition, of a second ethylene copolymer (A2) comprising a copolymer of ethylene and at least the first α-olefin comonomer, with a density as determined according to ISO 1183-187 ranging from 920 to 960 kg/m3; 40 to 80 wt.%, relative to the total weight of the multimodal ethylene copolymer composition, of a third ethylene copolymer (B) comprising a copolymer of ethylene and at least the first and a second α-olefin comonomer; wherein said third ethylene copolymer (B) has a higher weight-average molecular weight (Mw) than said first ethylene copolymer (A1) and said second ethylene copolymer (A2); wherein the composition has a density as determined according to ISO 1183-187 in the range of from 915 to 930 kg/m3; an MFR5, determined according to ISO1133, in a range of from 0.5 to 5.0 g/10min; and wherein a content of the second α-olefin comonomer in said third ethylene copolymer (B) is in a range of from 15 to 85 % based on the total comonomer content on mol basis in said third ethylene copolymer (B). A process for preparing the composition and films comprising the composition are also disclosed. |
