PROBLEM TO BE SOLVED: To provide a polyolefin-based resin composition for extrusion foaming capable of providing expanded material which has a high expansion ratio and is flexible regardless of a melt tension of a polyolefin-based resin, and to provide a polyolefin-based resin expanded material obtained by the polyolefin-based resin composition for extrusion foaming.SOLUTION: The polyolefin-based resin composition for extrusion foaming contains (a) a polyolefin-based resin, and (b) (b1) an elastomer and (b2) a plastomer, where the mixing ratio of (a) and (b) is in the range of 90/10 to 10/90 by a mass ratio, and the mixing ratio of (b1) and (b2) is in the range fo 90/10 to 10/90 by a mass ratio. |
