Zusammenfassung:	The present invention deals with a multilayer structure comprising a first polyethylene layer as a first external layer. The first polyethylene layer is oriented in at least machine direction. The structure also comprises a second polyethylene layer as a second external layer. It further comprises a layer made of a copolymer of ethylene and vinyl alcohol (EVOH) between the first external layer and the second external layer and a tie layer on each side of the EVOH layer. Furthermore, the tie layers comprise one or more copolymers of ethylene.
