摘要：
A polypropylene resin having: (1) a melt flow rate (MFR) of 6 to 100 g/10 minutes, (2) a molecular weight distribution (Mw/Mn), measured by gel permeation chromatography, of 3 to 6, and (3) a 116° C. non-eluted component content (100-W116(%)) of 50% or more and a content of components eluted at 90° C. or less (W90) of 10 to 30%, measured by temperature-rising fractional chromatography (TREF).
