Beschreibung
Zusammenfassung:	A multilayer comprises at least one first layer and at least one second layer. The first layer comprises a water-soluble polymer, wherein the first layer has an oxygen barrier. Furthermore, the first layer comprises a salt. The salt can act as a lubricant. The second layer has a water vapor and/or humidity barrier. The multilayer can offer a high barrier-performance with respect to oxygen permeation and permeation of water / humidity. This enables for a broad applicability of the multilayer in various areas as e.g. in packing, in particular for food packing, in particular for packing coffee.
