Abstract

The present invention relates to a multilayer film comprising: • an inner layer system comprising a first surface and a second surface; • a first skin layer bound to the inner layer system at the first surface of the inner layer system; and • a second skin layer bound to the inner layer system at the second surface of the inner layer system; wherein • the inner layer system comprises a first ethylene-based polymer; and • at least one of the first or the second skin layer(s) is a sealing layer and comprises a second ethylene-based polymer having a peak melting temperature Tof at least 10° C. below the Tof the first ethylene-based polymer, Tbeing determined as peak melting temperature in accordance with ASTM D3418 (2008); wherein the multilayer film is a bi-directionally oriented film wherein the orientation is introduced in the solid state. Such film allows for the production of a sealed package having a sufficiently high sealing strength at reduced sealing temperatures, also referred to as the seal initiation temperature.
