Arrangement for manufacturing a web-shaped packaging laminate (9), comprising an extruder (3) arranged so as to extrude a film (5) of polymer material down into a nip between a cooling roll (1) and a counter-roll (2), and also means of introducing at least one other layer (4) of the packaging laminate into the said nip for joining the film (5) together with the layer (4). According to the invention, the arrangement comprises an arrangement (6) for covering the cooling roll (1) with a surface layer of a water-based composition (7) comprising a dry matter content. The invention also relates to the method for manufacturing the web-shaped packaging laminate (9), in which the composition (7) is transferred as a thin layer to the film (5) of polymer material in the nip, while the film of polymer material is still hot.
