摘要

Disclosed is an ethylene polymer composition containing the component (A), the component (B) and the component (C) defined below. The component (A) is contained in an amount of 120-1700 parts by weight per 100 parts by weight of the component (B), and the component (C) is contained in an amount of 3-20 parts by weight per 100 parts by weight of the component (B). Component (A): an ethylene-a-olefin copolymer satisfying all of the following conditions (a1)-(a3). (a1) The density is within the range of 890-925 kg/m<SUP>3</SUP>. (a2) The melt flow rate (MFR) is within the range of 0.1-30 g/10 minutes. (a3) The flow activation energy (Ea) is less than 50 kJ/mol.
