PURPOSE:To improve transparency by orienting a polypropylene resin containing an alkenyl silane polymer in at least the uniaxial direction. CONSTITUTION:A polypropylene resin including a 0.1wt.ppm-2wt.% alkenyl silane polymer composed of repeated units shown in formula I (in formula, (n) represents an integer of 0-2 and R<1>, R<2>, R<3> an alkyl group, a cycloalkyl group or an aryl group) is oriented in at least the uniaxial direction. A film acquired has extremely excellent transparency and see-through feeling. |
