摘要： The present invention relates to [1] a polypropylene-based resin composition satisfying the following requirements (1) and (2) in a differential molecular weight distribution curve which is obtained from measurement by the gel permeation chromatography using polystyrene as a conversion standard, and in which the abscissa represents a logarithmic value log(M) of a molecular weight M, and the ordinate represents a dw/dlog(M) value obtained by differentiating a concentration fraction w by the logarithmic value log(M) of the molecular weight:
(1) In the differential molecular weight distribution curve, a value obtained by integrating the dw/dlog(M) values in the range of (5.5 ≤ log(M)) is 25% or less relative to a value obtained by integrating the dw/dlog(M) values over the entire range of log(M); and
(2) In the differential molecular weight distribution curve, a value obtained by integrating the dw/dlog(M) values in the range of (log(M) ≤ 4.5) is more than 10% relative to a value obtained by integrating the dw/dlog(M) values over the entire range of log(M).
The present invention also relates to [2] a polypropylene-based resin composition having a melt flow rate (MFR) of 10 to 500 g/10 min and a half-crystallization time of more than 0.05 seconds; and further relates to [3] a polypropylene-based resin composition containing 40 to 99% by mass of a polypropylene-based resin (A) having a melting point (Tm-D) of higher than 120°C, 0.5 to 59.5% by mass of a polypropylene-based resin (B-1) having a melting endotherm (ΔH-D) of 0 to 80 J/g, and 0.5 to 59.5% by mass of a wax (B-2).
