ABSTRACT:
A method for producing packaging material in web form comprising a carcass layer having through holes, openings or slits, a barrier layer on one side of the carcass layer, a plastic lining arranged outside the barrier layer, and a laminant thermoplast arranged between the carcass layer and barrier layer. The method involves bringing the barrier layer at the same time as the carcass layer to adhere to the plastic lining and/or to the laminant thermoplast film in a press nip. The press nip comprises an impression roller exhibiting a jacket surface faced with an inner facing layer of elastic material possessing a first hardness and a first thickness, and an outer facing layer of elastic material possessing a second hardness and a second thickness. The first hardness is greater than the second hardness and the first thickness is greater than the second thickness.
