Zusammenfassung:A recycling-friendly, easily producible paper packaging laminate with a high barrier against water vapor, oxygen and/or aromas is characterized in that a barrier film (3) comprises at least one substrate layer (4), a joining layer (5), and a 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 content or a polypropylene content of at least 60 wt.% 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 content of the paper layer (2) is between 50 wt.% and 90 wt.% 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.
