Coated bi-directionally oriented multilayer film

A multilayer film comprising:

• an inner layer system comprising a first surface and a second surface;
• a first layer bound to the inner layer system at the first surface of the inner layer system;
• and
• a second layer comprising a first surface and a second surface, wherein the second layer is with its first surface bound to the inner layer system at the second surface of the inner layer system;
• a coating layer bound to the second layer at the second surface of the second layer;
• wherein
• the inner layer system consists of a polymer formulation (A) comprising ≥10.0 and ≤90.0 wt % of a linear low-density polyethylene (LLDPE-A) and ≥10.0 and ≤90.0 wt % of a high-density polyethylene (HDPE) having a density of ≥940 and ≤970 kg/m3, as determined in accordance with ASTM D792 (2008);
• the first layer consists of a polymer formulation (B) comprising a linear low-density polyethylene,
• the second layer consists of a polymer formulation (C) comprising or consisting of a modified polyethylene;
• and
• the coating layer comprises or consists of a polyurethane;
• wherein the multilayer film is a bi-directionally oriented film wherein the orientation in both directions is introduced in the solid state, and
• wherein the LLDPE-A has:
• a fraction that is eluted in analytical temperature rising elution fractionation (a-TREF) at a temperature ≤30.0° C. of ≥3.0 wt %, with regard to the total weight of the LLDPE-A.
