Abstract:
A polypropylene resin composition comprising polypropylene as a main component, said polypropylene resin composition having the characteristic features:1) a melt flow rate (MFR), determined at 230Â° C. under a load of 2.16 kg, in the range of 0.01-5 g/10 min, 2) a content of a high molecular weight polypropylene exhibiting an intrinsic viscosity (&eegr;), determined at 135Â° C. in decalin, of 8-13 dl/g in the range of 15-50% by weight, 3) a gel areal density in number of 3,000/450 cm2 or less, and 4) a molecular weight distribution, determined by gel permeation chromatography (GPC), in the range of 6-20 for Mw/Mn and 3.5 or higher for Mz/Mw.
