[54] A MONOLAYER AND A MULTILAYER MACHINE DIRECTION ORIENTED FILM COMPRISING LLDPE AND A PROCESS FOR THE FORMATION OF A MONOLAYER OR MULTILAYER
[57] Abstract: A multilayer machine direction oriented film comprising at least an (A) layer and (B) layer, at least one of said (A) layer or (B) layer comprising at least 50 wt% of a multimodal linear low density polyethylene (LLDPE) having a density of 905 to 940 kg/m3 and an MFR2 of 0.01 to 20 g/10min and comprising a lower molecular weight (LMW) component and a higher molecular weight (HMW) component;wherein said LMW component is an ethylene homopolymer and said HMW component is an ethylene polymer of ethylene with at least two C4-12 alpha olefins;wherein said film is a stretched film which is uniaxially oriented in the machine direction (MD) in a draw ratio of at least 1:3 and has a film thickness of at least 40 microns (after stretching) and wherein said film does not comprise a layer in which more than 50 wt% of said layer comprises a polymer component having a melting point (Tm) of 100°C or less.
