Beschreibung
Zusammenfassung:	A biaxially stretched polypropylene film (100) comprising a biaxially stretched film layer (101) containing a propylene-based polymer, wherein the long period of crystals in the TD direction obtained by a small-angle X-ray scattering (SAXS) measurement is 28.0 nm or less. Film de polypropylène étiré biaxialement (100) comprenant une couche de film étiré biaxialement (101) contenant un polymère à base de propylène, la période longue des cristaux dans la direction TD obtenue par une mesure de diffraction des rayons X aux petits angles (SAXS) étant égale ou inférieure à 28,0 nm. プロピレン系重合体を含む二軸延伸フィルム層（１０１）を備え、小角Ｘ線散乱（ＳＡＸＳ）測定から求められるＴＤ方向の結晶長周期が２８．０ｎｍ以下である、二軸延伸ポリプロピレンフィルム（１００）。
