CA 2465964

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/10min, said multimodal ethylene polymer comprising from 35 to 65wt%, 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 35wt% 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/10min 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.

L'invention concerne une capsule à vis, qui comprend une composition à base de polymère d'éthylène multimode présentant une densité normale (SD) supérieure à 950 kg/m?3¿ et un indice de fluage MI¿2? inférieur à 10 g/10min. Ledit polymère d'éthylène multimode comprend, sur la base de son poids total: entre 35 et 65 % en poids d'une fraction d'un polymère d'éthylène (A) présentant une SD(A) supérieure à 950 kg/m?3¿ et un indice de fluage MI¿2?(A) d'au moins 10 g/10min; et entre 65 et 35 % en poids d'une fraction d'un copolymère d'éthylène (B) et au moins une alpha-oléfine contenant 3 à 12 atomes de carbone et présentant un indice de fluage MI¿2?(B) inférieur à 10 g/10min et une teneur de ladite (desdites) alpha-oléfine(s) comprise entre 0,1 et 5 % en moles. La composition de l'invention est réputée présenter un excellent équilibre entre l'ESCR, l'injectabilité et la résistance au choc, ainsi que d'excellentes propriétés organoleptiques.
