Abstract: The invention relates to a coated packaging material that has a substrate having a base material of cellulose, an outer side to be faced away from the packaging item as well as an inner side to be faced towards the packaging item. The inner side of the substrate carries at least one layer of an aqueous composition, which includes at least polyvinyl alcohol and/or at least one polyvinyl alcohol copolymer as well as a cross-linking agent, wherein the aqueous composition has at most 40% by wt. of polyvinyl alcohol and/or polyvinyl alcohol copolymer and a total solid content of at most 55% by wt. The layer and cross-linking the polyvinyl alcohol and/or the polyvinyl alcohol copolymer is dried with the aid of the cross-linking agent with formation of a barrier layer for hydrophobic compounds are performed.

Abstract: The invention relates to a method for producing a coated packaging material, in which at least the steps of a) providing a substrate having a base material of cellulose, an outer side to be faced away from the packaging item as well as an inner side to be faced towards the packaging item, b) coating at least the inner side of the substrate with at least one layer of an aqueous composition, which includes at least polyvinyl alcohol and/or at least one polyvinyl alcohol copolymer as well as a cross-linking agent.

Abstract: The invention relates to a method for producing a coated packaging material (10), wherein at least the following steps are carried out: a) providing a substrate (12), which has a base material (14) made of cellulose, an outside (16) to face away from a good to be packaged, and an inside (18) to face the good to be packaged; b) coating the inside (18) of the substrate with at least one layer of an aqueous composition, which comprises at least polyvinyl alcohol and a cross-linking agent and has a solid content of at most 25 wt %; and c) drying the layer and cross-linking the polyvinyl alcohol by means of the cross-linking agent in order to form a barrier layer (22a, 22b) for hydrophobic compounds. The invention further relates to a packaging material (10) having at least one barrier layer (22a, 22b) for hydrophobic compounds.
