The invention relates to the use linear polyethylene having an MIR indicative of the presence of some long chain branching having a density of 0.91 to 0.94 g/cm 3 determined according to ASTM D4703/D1505, an I 2.16 (MI) of from 0.05 to 1 g/10 min, and I 21.6 /I 2.16 (MIR) of more than 35, the MI and MIR being determined according to ASTM 1238 D at 190°C, and a difference between the MD Tensile force based on ASTM D882-02 at 100% elongation and MD 10% Offset yield of a reference film as defined herein having a thickness of 25 μm of at least 15MPa.The invention also relates to coextruded film structures made using such linear polyethylene in the core layer of a multi-layer structure to provide easily processes, strong, highly transparent films. |
