PURPOSE:To obtain the subject film free from a trouble of fine powder scattering of an inorganic filler, by stretching an unstretched film composed of a polyamide resin with a low melting point and a thermoplastic polyester resin with a specified particle size and low intrinsic viscosity. CONSTITUTION:An unstretched film composed of (A) 100pts.wt. polyamide-based resin (preferably nylon-6/66, nylon-6/12, nylon-6/66/12, nylon-11 or nylon 12) with <=200 deg.C melting point and (B) 25-90pts.wt. thermoplastic polyester resin with <=0.5 intrinsic viscosity and 0.05-30mum, preferably 0.05-20mum particle size as the essential components is stretched at least in one axis, thus obtaining the objective film. |
