    • 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.
    • 一种生产网状包装材料的方法,包括具有通孔,开口或狭缝的胎体层,胎体层一侧的阻挡层,布置在阻挡层外侧的塑料衬里,以及布置在胎体层之间的层压热塑性塑料 和阻挡层。 该方法包括使阻挡层与胎体层同时粘附到塑料衬里和/或在压榨压区中粘附到层压体热塑性塑料膜。 压榨压区包括压印辊,其具有面向具有第一硬度和第一厚度的弹性材料的内表面层的外套表面和具有第二硬度和第二厚度的弹性材料的外侧层。 第一硬度大于第二硬度,第一厚度大于第二厚度。
