Abstract
A multilayer film includes an inner layer system having 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 first ethylene-based polymer being LLDPE-A; and ≥10.0 and ≤90.0 wt % of HDPE having a density of ≥940 and ≤970 kg/m; the first layer contains a polymer formulation (B) including LLDPE-A, the second layer contains a polymer formulation (C) including a modified polyethylene; and the coating layer includes a polyurethane; wherein the multilayer film is a bi-directionally oriented film, and the orientation in both directions is introduced in the solid state. Such multilayer film exhibits reduced oxygen transmission rates and/or water vapour transmission rates.
