1. A film comprising:
a polyethylene composition comprising a first polyethylene comprising at least one C3-C20-olefin-comonomer, wherein the polyethylene composition has a density from 0.90 to 0.935 g/cm3, a normalized shear thinning index SHI*(0.1 rad/s) less than 0.95 with SHI*(ω)=η*(ω)/η0, a molecular mass distribution from 3 to 5, and a dart drop impact value, as measured by ASTM D 1709:2005 Method A on 25 μm blown films, of at least 1200 g. |
