Abstract
A polyolefin resin composition containing an ethylene-.alpha.-olefin copolymer having: (A) a density d of 0.86 to 0.96 g/cm.sup.3 ; (B) a melt flow rate MFR of 0.01 to 200 g/10 min; (C) a molecular weight distribution Mw/Mn of 1.5 to 4.5; (D) a composition distribution parameter Cb of 1.08 to 2.00; and (E) an orthodichlorobenzene-soluble content X (wt %), at 25.degree. C. a density of d (g/cm.sup.3) and a melt flow rate MFR (wt %) satisfying that: (i) when the density (d) and the melt flow rate MFR satisfy relationship (I): d-0.008.times.logMFR.gtoreq.0.93 (I) the orthodichlorobenzene-soluble content X satisfies relationship (II): X<2.0 (II) (ii) when the density d and the melt flow rate MFR satisfy relationship (III): d-0.008.times.logMFR<0.93 (III) the orthodichlorobenzene-soluble content X satisfies relationship (IV): X<9.8.times.10.sup.3 .times.(0.9300-d+0.008.times.logMFR).sup.2 +2.0(IV)
