PURPOSE:To obtain the title film useful as a packaging material having excellent transparency, mechanical characteristics, slipperiness and blocking resistance, by uniformly dispersing fine powder composed of a specific thermoplastic resin and inorganic fine powder into a polypropylene film. CONSTITUTION:(A) 0.01-0.2wt.% fine powder composed of a thermoplastic resin (preferably polyamide resin or polyester resin) which has a higher melting point than a polypropylene, is not substantially compatibilized with the polymer and has preferably 0.1-10mum particle diameter and (B) 0.01-0.5wt.% inorganic fine powder (e.g. talc or silica) are uniformly dispersed into the polypropylene to give the objective film having 0.3-0.6 coefficient of weaving obtained from the formula. |
