    Titre: Method and apparatus for preparing fold lines
    Contributeur: SIG Technology AG (Corporate Author)
    Date: 25 November 2014
    Description: The method and the apparatus are used for preparing fold lines on laminated materials on the basis of cardboard. At least one region intended for providing the fold line is subjected to heat such that an at least partial local reduction of shear fracture stresses of the material is produced in said region. The application of heat is done using a heating device, which is disposed adjacent to a guide device for the laminate. The local reduction of the shear fracture stresses supports local delamination, which supports the formation of a folding joint.

    Titre: Reclosable pouring element with barrier film and a support wall
    Contributeur: SIG Technology AG (Corporate Author)
    Date: 19 January 2016
    Description: A reclosable pouring element for liquids contained in packagings, in particular liquid food, including a base body, which has a pouring opening, an external thread and a flange for connection to the packaging, a cutting ring, which has a cutting edge and a projection, and a screw lid, which has an internal thread and an actuator, the pouring opening being closed by a barrier film. To achieve improved protection of the barrier film against damage while still having a reliable opening function of the pouring element, it is proposed that the base body has a support wall, on which the barrier film rests.

    Titre: Method and device for sterilising edges of packaging material
    Contributeur: SIG Technology AG (Corporate Author)
    Date: 19 April 2016
    Description: Disclosed is a method for processing cut edges of a blank member, so galled "package sleeve", made from packaging material, in particular paper/plastics composite material, the cut edges of which are open from above and/or below, by applying a processing medium. In order to develop a simple and cost-effective method, in which the risk of contamination of the packagings and the aseptic region of a filling installation when the package sleeves are filled and closed is reduced, the processing medium contains at least one sterilizing medium and the sterilizing medium remains after being applied to the cut edges and is introduced into the packaging material.

    Titre: Device and method for sealing overlapping packaging parts
    Contributeur: SIG Technology AG (Corporate Author)
    Date: 12 September 2017
    Description: A device and method for the fluid-tight sealing of two partially overlapping packaging components, one being a tubular base member formed from a blank of composite cardboard/plastics material, and an additional packaging component forming the upper packaging portion or packaging base, having at least one mandrel and one die, the mandrel having at least two expansion elements which are moved from the operating position thereof towards each other into a rest position, the expansion elements having sealing jaws which, in the operating position thereof, form a closed circumferential outer contour, which corresponds to an inner contour formed by an opening in the die, there remaining between the inner contour and outer contour a narrow annular gap in order to apply a pressing force from the inner side to the overlap region of the packaging components.

    Titre: Planar composite with layers of plastic of different Vicat softening temperatures
    Contributeur: SIG Technology AG (Corporate Author)
    Date: 27 February 2018
    Description: The present invention generally relates to a sheetlike composite comprising a layer configuration with at least the following layers: i. a first layer of thermoplastic KSu; ii. a carrier layer; iii. a barrier layer; iv. a second layer of thermoplastic KSw; wherein the sheetlike composite has at least one further layer of thermoplastic KSv; wherein the Vicat softening temperature of the layer of thermoplastic KSu is higher than the Vicat softening temperature of the layer of thermoplastic KSw. The present invention furthermore relates to a process for the production of the sheetlike composite, a container surrounding an interior which comprises at least one such sheetlike composite, and a process for the production of this container.

    Titre: Robust planar composite with an intermediate layer of increased vicat softening temperature
    Contributeur: SIG Technology AG (Corporate Author)
    Date: 27 February 2018
    Description: The present invention generally relates to a sheetlike composite comprising a layer configuration with the following layers: 0. optionally a layer of thermoplastic KSu; 1. a carrier layer; ii. a first layer of thermoplastic KSv; iii. a barrier layer; iv. a second layer of thermoplastic KSa; v. at least one further layer of thermoplastic KSw; wherein the Vicat softening temperature of the layer of thermoplastic KSv and the Vicat softening temperature of the layer of thermoplastic KSa is in each case higher than the Vicat softening temperature of the layer of thermoplastic KSw. The present invention furthermore relates to a process for the production of the sheetlike composite, a container which surrounds an interior and comprises at least one such sheetlike composite, and a process for the production of this container.

    Titre: Device for changing the jet shape of free-flowing products
    Contributeur: SIG Technology AG (Corporate Author)
    Date: 23 January 2018
    Description: A device for changing the jet shape of free-flowing products, in particular of foodstuffs, including: an inflow area for the free-flowing products to enter, an outflow area for the free-flowing products to exit, and several channels through which to pass the free-flowing products. Each channel includes an inlet allocated to the inflow area and an outlet allocated to the outflow area. The inlets together form an inflow surface with a width and height lying in the inflow area. The outlets together form an outflow surface with a width and height lying in the outflow area. In order to reduce splashing when filling packagings with a non-rotationally symmetrical cross section, the outflow surface is non-rotationally symmetrical.

    Titre: Method and device for sanitizing packagings
    Contributeur: SIG Technology AG (Corporate Author)
    Date: 19 May 2015
    Description: The method and the apparatus serve for disinfecting packaging formed at least in part as packaging sleeves closed all the way around. A disinfectant is applied to the packaging. The packaging sleeves are opened in a longitudinal direction of the sleeve in the region of both ends during the disinfection process and are transported through a disinfection tunnel. The disinfectant is applied to the packaging sleeves inside the disinfection tunnel. Along the disinfection tunnel, disinfectant flowing out of an opened end section of a packaging sleeve is introduced into an opened end section of an adjoining packaging sleeve.
