본 발명은 특히 취입 성형 중공 물품들을 제조하기에 적합하고, 특히 하기 특징들을 갖는 폴리에틸렌 조성물에 관한 것이다. 1) 0.957 내지 0.968g/cm3의 밀도; 2) 12 내지 30의 MIF/MIP 비율; 3) 41 내지 60g/10min.의 MIF; 4) 0.45와 같거나 더 큰 장쇄 분지 지수(LCBI); 5) 45 내지 75의 η0.02/1000)/LCBI 비율. A polyethylene composition particularly suited for producing blow-molded hollow articles, having the following features: 1) density from 0.957 to 0.968 g/cm3; 2) ratio MIF/MIP from 12 to 30; 3) MIF from 41 to 60 g/10 min.; 4) long-chain branching index, LCBI, equal to or greater than 0.45; 5) ratio (η0.02/1000)/ LCBI from 45 to 75.
