Multilayer film which comprises a core layer (C) and two outer layers (O—, O-2) sandwiching the core layer, wherein (i) the core layer (C) comprises a bimodal ethylene/1-butene/C6-C12-alpha-olefin terpolymer, (ii) one outer layer (O-1) comprising (ii-1) a low density polyethylene or (ii-2) the bimodal terpolymer as defined for the core layer (C) or (ii-3) a metallocene produced linear low density polyethylene and optionally a low density polyethylene (iii) the other outer layer (O-2) comprising (iii-1) a metallocene produced linear low density polyethylene and optionally a low density polyethylene, and its use for packaging, especially for frozen food packaging.
