Abstract
Disclosed is a polyolefin composition for stretched film including an olefin-based polymer (A) having a melting endotherm (ΔH-D), as obtained from a melting endothermic curve which is obtained under a measurement condition of holding a sample at −10° C. for 5 minutes in a nitrogen atmosphere and then increasing the temperature at a rate of 10° C./min with a differential scanning calorimeter (DSC), of 0 to 80 J/g; and an olefin-based polymer (B) having a melting endotherm (ΔH-D), as observed under the foregoing measurement condition, of more than 80 J/g, wherein a content of the olefin-based polymer (A) is 0.5% by mass or more and less than 17% by mass relative to a total content of the olefin-based polymer (A) and the olefin-based polymer (B), and the polyolefin composition has a melting endotherm (ΔH-D), as observed under the foregoing measurement condition, of 80 to 120 J/g.
