摘要： The polymer composition (1) comprises a water-soluble polymer composition (12) and a salt (3). The pH-value of the polymer composition is 4.5 to 5.5. This enables a stable polymer composition (1). The polymer composition (1) can be compatible with food contact and enables a packaging of food, with a water-soluble polymer composition.

摘要： 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.

摘要： The polymer composition (1) comprises a water-soluble polymer (12) and a salt (3). The polymer composition (1) is non-corrosive to metal. This means, that the polymer composition (1) does not cause corrosion. In particular, the polymer composition (1) does not cause corrosion to the processing machine under processing conditions of the polymer composition (1). Processing conditions of the polymer composition may include elevated temperature in an extrusion process.
