PURPOSE: To obtain a resin composition that can give a biaxially stretched film having less stretch voids and excellent in visual film appearance. CONSTITUTION: A crystalline polypropylene, an additive that is solid under mixing conditions, and an additive that is liquid under the mixing conditions are mixed, then are molded by heating, are mixed, and are granulated to produce a polypropylene resin composition for stretch, in which as the crystalline polypropylene, a polypropylene wherein the catalyst residue measured by the incineration method is 100ppm or less and the chlorine content is 50ppm or less is used, and under the mixing conditions, the solid additive and the crystalline polypropylene are charged into a mixer and are mixed, and then the liquid additive is charged, followed by mixing. |
