Abstract

The present invention relates to a polypropylene-based composite, including (A) polypropylene, and (B) an olefin-based polymer satisfying the following conditions: (1) a melt index (MI, 190° C., 2.16 kg load conditions) is from 0.1 g/10 min to 10.0 g/10 min, (2) a density (d) is from 0.860 g/cc to 0.880 g/cc, and (3) T(90)-T(50)≤50 and T(95)-T(90)≥10 are satisfied, wherein T(50), T(90) and T(95) are temperatures at which 50%, 90%, and 95% are melted, respectively, when fractionating a temperature-heat capacity curve from measurement results by the differential scanning calorimetry precise measurement method (SSA). The polypropylene-based composite of the present invention may show excellent impact strength.
