Abstract:
The present invention relates to a film comprising at least one layer comprising an ethylene homo- or copolymer which has a complex viscosity at 5 kPa shear stress eta5 of 200,000 or less and a shear thinning index SHI(5/300) measured at 190° C. as the ratio between the complex viscosity at 5 kPa shear stress and the complex viscosity at 300 kPa shear stress of 120 or more.
