To provide polypropylene resin compositions capable of providing films excellent in rigidity, transparency, sliding properties, anti-block properties and resistance to whitening with time, and films composed thereof.

Polypropylene compositions comprise 99.5-99.99 pts.wt. polypropylene resin material containing 2-5 wt.% 40°C extract by o- dichlorobenzene as the solvent having 50 wt.% propylene units whose number average molecular weight is 3,000-100,000 and further having a difference in amount between the 90°C extract and the 40°C extract of not more than 5 wt.% and a melt peak temperature by differential scanning calorimetry(DSC) of not lower than 150°C; and 0.01-0.5 pt.wt. fatty acid amide, and films are molded with the used of these polypropylene resin compositions.
