PROBLEM TO BE SOLVED: To provide a resin composition for polypropylene film which causes no problems, for example, bleed whitening or deposition of the lubricant to molding machine chamber and has markedly improved lubrication properties particularly in laminated films, and provide multilayered film and laminated film. SOLUTION: This resin composition is prepared by formulating (B) 0.05-1 pt.wt. of a lubricant to 100 pts.wt. of (A) polypropylene resin containing more than 30wt.% of a propylene-ethylene copolymer having (a) a melt index of 2-12g/10min., (b) the melting calorieΔH of <=90J/g according to the differential scanning type calorie meter, (c) the proportion insoluble in p-xylene is 75-95wt.%, after dissolving in boiled p-xylene, 0.5-5wt.% of the ethylene monomer content in the insoluble fraction and the fraction dissolving in boiled p-xylene, and still soluble, after being cooled down to 25 deg.C has an intrinsic viscosity [η]=1.2-3.0dl/g in decalin at 35 deg.C.
