The invention relates to a cast film obtained from a polypropylene composition comprising a) at least 95 wt.-% (based on the overall weight of the polyolefin composition) of at least one polypropylene homopolymer PPH having a molecular weight distribution Mw/Mn measured by GPC (according to ISO 16014-4:2003 and ASTM D 6474-99) in the range of 2.8 to 3.5, a MFR2 (ISO1133, 2.16 kg load at 230 °C) between 2.5 and 5.0 g/10 min, and a sum of 2,1-insertion in the range of 0.3 to 1.5 mol% as determined by 13C nuclear magnetic resonance (NMR) spectroscopy, a melting temperature (Tm) (measured according to ISO 11357/part 3/method C2) in the range of 145°C to 160°C, a xylene cold soluble (XCS) content determined according to ISO 16152 based on the overall weight of polypropylene homopolymer of less than 1.5 wt.-%, and b) up to 5 wt.-% of one or more additives, wherein the sum of all ingredients always adds up to 100 wt.-%. The invention relates also to the use of said cast film in pharmaceutical packaging systems.
