Abstract: A screw cap is disclosed comprising a composition based on a multimodal ethylene polymer having a standard density (SD) greater than 950 kg/m3 and a melt flow index MI2 of less than 10 g/10 min, said multimodal ethylene polymer comprising from 35 to 65 wt %, based on the total weight of the multimodal ethylene polymer, of a fraction of ethylene polymer (A) having an SD(A) of more than 965 kg/m3 and a melt flow index MI2(A) of at least 10 g/10 min, and from 65 to 35 wt % based on the total weight of the multimodal ethylene polymer, of a fraction of a copolymer (B) of ethylene and at least one alpha-olefin containing from 3 to 12 carbon atoms, and having a melt flow index MI2(B) of less than 10 g/10 min and a content of said alpha-olefin(s) of from 0.1 to 5 mol %. This composition is said to demonstrate an excellent balance between ESCR, injectability and impact resistance, together with excellent organoleptic properties.
