Packaging laminate for a packaging container for oxygen-sensitive liquid food,such as milk, juice, wine and cooking oil. The packaging laminate (10) has a layer (11) of paper or paperboard, and a layer (12) serving as gas barrier and composed of a material with barrier properties against gases, in particular oxygen. The layer (12) serving as gas barrier is bonded to the paper or paperboard layer (11) by a lamination layer (13), which has a central layer (13a) of polymer and outer layers (13b and 3c) of an adhesive on both sides of the polymer layer (13a). The packaging laminate (10) also has outer liquid-tight coatings(14 and15) on both sides of the paper or paperboard layer (11). |
