摘要： Disclosed are a polypropylene resin composition comprising a crystalline polypropylene having a high stereoregularity and a terpene resin and a petroleum resin each having no polar group; a polypropylene stretched film formed from the polypropylene resin composition; and a polypropylene multi-layer stretched film having a base layer formed from the polypropylene resin composition and a surface layer formed from a polypropylene type polymer. The polypropylene stretched film and a polypropylene multi-layer stretched film have excellent water-vapor barrier properties and transparency, and a high Young's modulus. Further, disclosed are a polypropylene resin composition comprising a crystalline polypropylene having a high stereoregularity and a hydrogenated petroleum resin; a PTP packaging polypropylene sheet formed from the polypropylene resin composition; and a PTP packaging polypropylene multi-layer sheet having a base layer formed from the polypropylene resin composition and a surface layer formed from a propylene type polymer, wherein the proportion of the thickness of the base layer to the total thickness of the sheet is more than 50 %, and the total thickness of the sheet and the proportion of the thickness of the base layer satisfy the specific relationship. The PTP packaging polypropylene sheet and the PTP packaging polypropylene multi-layer sheet have excellent water-vapor barrier properties and transparency, and a high rigidity.
