Abstract: The invention provides a biaxially oriented film comprising a multimodal high density polyethylene (HDPE), wherein the multimodal HDPE has a density determined according to ISO 1183 in the range of 952 to 968 kg/m3 and an MFR2 of 0.3 to 3.0 g/10) min when measured at 190° C. with a load of 2.16 kg according to ISO 1133, and wherein the multimodal HDPE comprises at least two fractions: (C) 30 to 70 wt % relative to the total weight of the multimodal HDPE, of a lower molecular weight fraction being a polyethylene with a density in the range of 955 to 980 kg/m3 and an MFR2 of 100 to 2000 g/10 min when measured at 190° C. with a load of 2.16 kg according to ISO 1133; and (D) 30 to 70 wt % relative to the total weight of the multimodal HDPE, of a higher molecular weight fraction being a polyethylene with a density in the range of 925 to 970 kg/m3 and an MFR2 of 0.0001 to 1.0 g/10 min when measured at 190° C. with a load of 2.16 kg according to ISO 1133.
