Ethylene-alpha-olefin copolymer, resin composition containing same and biaxially stretched film thereof

摘要

An ethylene-alpha-olefin copolymer resin having a melt index of 0.5 to 2.0 g/l0 minutes and a density of 0.905 to 0.920 g/cm³ and showing such a temperature raising elution fractionation pattern that the amount of fractions corresponding to a high density polyethylene is 8 to 25% of the total elution and that the amount of fractions eluted up to a temperature of T₄₀° C. is 40% of the total elution and the amount of fractions eluted up to a temperature of T₇₀° C. is 70% of the total elution, wherein the value of 30/(T₇₀-T₄₀) is 2.0 to 3.3% ° C.
