Abstract
A biaxially oriented polyethylene film structure comprises at least three layers, at least one layer comprising a polyethylene composition, the polyethylene composition having a density of from 0.941 to 0.962 g/cm; a melt index, Iof from 0.5 to 5.0 g/10 min; and a molecular weight distribution Mw/Mn, of from 3.0 to 8.0. The biaxially oriented film has good optical properties.
