RECYCLABLE PAPER PACKAGING WITH HIGH BARRIER TO WATER VAPOR AND OXYGEN

A recycling-friendly, easily producible paper packaging laminate with a high barrier to water vapor, oxygen and/or aromas is characterized in that a barrier film (3) comprises at least a substrate layer (4), joining layer (5) and barrier layer (6), wherein the joining layer (5) is arranged between the substrate layer (4) and the barrier layer (6), in that the substrate layer (4) consists predominantly of polyethylene or polypropylene with a polyethylene fraction or a polypropylene fraction of at least 60% by weight of the substrate layer (4), in that at least the at least one substrate layer (4) of the barrier film (3) is stretched, in that the proportion of the paper layer (2) is between 50% by weight and 90% by weight of the paper packaging laminate (1), and in that the barrier film (3) is joined to the paper layer (2) by a hydrophilic adhesive layer (9), wherein the side of the paper layer (2) facing the barrier film (3) is uncoated.
