PURPOSE: To obtain a PP resin composition for a drawn film having excellent blocking resistance, transparency and scratch resistance and useful as a packaging film, etc., by compounding a PP resin with a specific crushed silica fine powder at a specific ratio. CONSTITUTION: This resin composition is produced by compounding (A) 100 pts.wt. of a PP resin with (B) 0.03-0.30 pts.wt. of a crushed silica fine powder surface-treated with a polyorganosiloxane such as a polyalkylsiloxane. The PP resin preferably has a melt flow rate of 1.0-5.0g/10min. |
