ABSTRACT:
A resin composition for injection molding that has excellent transparency, and also has excellent strength and sufficient flexibility. The composition contains 50 to 99% by weight of component A, which is a copolymer of ethylene and .alpha.-olefin having a carbon number of not less than 4, and 1 to 50% by weight of component B, which is an olefin-containing polymer. The component A has: (a) a melt flow rate (MFR) of 10 to 120 g/10 min.; (b) a density (D) of not more than 0.915 g/cm.sup.3 ; and (c) at least one peak of elution volume indicated by an elution curve obtained by temperature rising elution fractionation (TREF), wherein the peak corresponds to a temperature of not more than 85.degree. C., and the elution curve may also indicate substantial elution volume at temperatures other than the temperature to which the peak corresponds.
