  • Patent number: 10611117
    Abstract: A packaging laminate includes a core layer having at least one through-hole which on one side is covered by a barrier film and an outer layer of a polymeric material, wherein said outer polymeric layer and said barrier film are laminated to each other in a manner such that said polymeric layer and said barrier film are separated from each other along parallel, visually detectable air-filled channels formed by these two layers within the area of said at least one through-hole.

  • Patent number: 8871318
    Abstract: A packaging laminate comprising a core layer of paper or carton with through-going holes, openings or slits, a first layer of heat sealable thermoplastic material applied on the outermost side of the packaging laminate, a second layer of heat sealable thermoplastic material applied on the other, innermost side of the packaging laminate, one or more barrier layers applied between the core layer and the innermost thermoplastic layer, the thermoplastic material and barrier layers all being laminated to each other within the regions of said holes to form a membrane of barrier and thermoplastic material layers. A method for manufacturing of the packaging laminate and a packaging container that is made from the packaging laminate.

  • Patent number: 8591687
    Abstract: A lamination station for laminating a film to a web of paperboard includes a nip roller and a cooling roller. Between the rollers there is formed a nip which presses together the film and the web of paperboard with an interjacent molten polymer layer or adhesive layer disposed between the film and the web of paperboard. The film, the paperboard and the molten polymer lie, after the nip, in abutment against the cooling roller for a certain angle interval. The nip roller is a shoe-press type roller, either comprising a pressure bar having several hydraulically operated pressure elements, or comprising one or several rigid pressure bars.

  • Patent number: 6898989
    Abstract: A load cell comprising a load carrying structural framework is arranged with at least one measuring zone (15, 16) arranged with a measuring means. A load F applied in the x-direction parallel to two outer beams (1, 4) of the framework is transferred to two inner beams (2, 3) by two side beams (5, 6). The load on the measuring zones (15, 16) is greater than the load applied parallel to outer beams (1, 4) in a ratio of the distance h between the joints of the two outer beams divided by the distance d between the joints of the two inner beams. When a load is applied in the y-direction parallel to the two side beams (5, 6), the load on the measuring zones is also greater than the load applied at the side beams, in this case by a ratio of the distance l between the joints (7 and 11), (10 and 14) divided by distance d.
