Abstract:
1. Method for manufacturing a web-shaped packaging laminate comprising: feeding a web comprising at least one layer of the packaging laminate to a nip between a cooling roll and a counter-roll, the cooling roll possessing an outer surface; extruding a film of polymer material into the nip between the cooling roll and the counter-roll while the web is fed into the nip to join together the film of polymer material and the at least one layer of the web; transferring to the outer surface of the cooling roll a surface layer of a water-based composition comprising a dry matter content, the water-based composition comprising the dry matter content being transferred in a liquid form to the outer surface of the cooling roll; transferring the surface layer of the water-based composition on the cooling roll directly to the polymer material in the nip; and the web, the polymer material and the water-based composition forming a laminate which leaves the cooling roll.
