Abstract

A multilayer film comprises six layers in the layer arrangement 1/5/4/3/6/2. The first layer (1) serves as a heat sealing layer and comprises a homogeneous ethylene/alpha-olefin copolymer wherein the alpha-olefin has from 3 to 20 carbon atoms. The second layer (2) is a second outer layer and serves as an abuse layer. The third layer (3) is an O2-barrier layer and is between the first layer and the second layer. The fourth layer (4) is an inner layer comprising at least one member selected from the group consisting of polyamide and polyester. The fourth layer is between the fifth layer and the sixth layer. The fifth layer (5) is an inner layer serving as a first tie layer, the fifth layer being between the first layer and the third layer. The sixth layer is an inner layer serving as a second tie layer, the sixth layer being between the second layer and the third layer.A seventh layer comprising polyamide or polyester can be placed between the third and the sixth layer. The invention also pertains to a packaging article, such as a bag, pouch, casing, etc., which is made from or comprises the multilayer film as well as a packaged product comprising a product (e.g., food) surrounded by a package comprising the multilayer film.
