  • Patent number: 9248631
    Abstract: A packaging laminate includes at least one material layer provided with magnetizable particles. A roller can be configured to apply crease line patterns on the packaging laminate while also applying magnetic fields for magnetizing at least some of the magnetizable particles in the packaging laminate. A method of controlling working operations on a packaging laminate in a filling machine involves supplying a packaging laminate to a filling machine, wherein the packaging laminate includes at least one material layer comprising magnetizable particles, with at least some of the magnetizable particles being magnetized particles. The method also involves controlling working operations of the filling machine on the packaging laminate supplied to the filling machine by reading information provided by the magnetized particles.

  • Publication number: 20150375484
    Abstract: Packaging laminate for a packaging container for oxygen-sensitive liquid food, such as milk, juice, wine and cooking oil. The packaging laminate has a layer of paper or paperboard, and a layer serving as gas barrier and composed of a material with barrier properties against gases, in particular oxygen. The layer serving as gas barrier is bonded to the paper or paperboard layer by a lamination layer, which has a central layer of polymer and outer layers of an adhesive on both sides of the polymer layer. The packaging laminate also has outer liquid-tight coatings on both sides of the paper or paperboard layer.
