摘要： The multilayer (5) comprises at least one first layer (1) comprising water-soluble polymer, wherein the first layer (1) has an oxygen transmission barrier. The multilayer (5) further comprises at least one second layer (2), wherein second layer (2) has a water vapor and/or humidity barrier. The second layer (2) comprises a wax (20). The wax (20) can be in particular a natural wax, in particular food-safe wax, in particular biodegradable wax, in particular bee wax. The wax (20) enables to minimize the risk of migration of odours from and/or to the packaged goods. The multilayer (5) further comprises at least one third layer (3). The third layer (3) also comprises a water-soluble polymer. The first layer (1) comprises a first sublayer (11) and a second sublayer (12), both of which can comprise the water-soluble polymer.

摘要： The invention relates to a polymer composition comprising a crosslinked mixture of at least a water-soluble polymer and Polycaprolactone (PCL). The crosslinking of these components improves the water vapor and/or humidity barrier properties of the polymer composition, while keeping chemical and mechanical stability of the polymer composition. The invention also relates to a multilayer, which comprises at least one first layer comprising the polymer composition, wherein the first layer has an oxygen transmission barrier. The multilayer further comprises at least one second layer, wherein second layer has a water vapor and/or humidity barrier. The second layer comprises a wax. The wax can be in particular a natural wax, in particular food-safe wax, in particular bio-degradable wax, in particular bees wax.
