Abstract
The present invention is directed to a multimodal polyethylene copolymer comprising a first and a second copolymer of ethylene and at least two alpha-olefin comonomers. The multimodal polyethylene copolymer is highly suitable for the production of films providing high impact strength in the sense of high Dart drop impact strength (DDI) and low extractables. The invention further presents final articles such as films made therefrom.
