PURPOSE:To obtain the titled resin composition, having high stretchability and capable of providing films having sufficient moldability and mechanical strength even beyond elastic limits, by blending a specific amount of a plasticizer with ethylene/alpha-olefin copolymer having specific physical properties. CONSTITUTION:A resin composition obtained by blending (A) 100pts.wt. copolymer, prepared by copolymerizing ethylene with a >=3C alpha-olefin (preferably propylene or butene-1) and, as necessary, a nonconjugated diene and having <=2g/10min, preferably 0.1-2g/10min melt index, <=0.91g/cm<3>, preferably 0.85-0.91g/cm<3> density and <=30, preferably 5-25 flow ratio with (B) 0.1-20pts. wt., preferably 0.2-10pts.wt., particularly 0.2-5pts.wt. plasticizer (e.g. phthalic acid ester based or aromatic carboxylic acid based plasticizer), dry blending the components, as necessary, melt blending and pelletizing the resultant blend. |
