  • Publication number: 20110248076
    Abstract: A non-foil packaging laminate for liquid food packaging comprises a core layer of paper or paperboard, outermost liquid tight, heat sealable layers of polyolefin and, applied onto the inner side of the layer of paper or paperboard, an oxygen gas barrier layer formed by liquid film coating of a liquid gas barrier composition and subsequent drying, the liquid composition containing a polymer binder dispersed or dissolved in a liquid medium. The laminate further comprises a layer of a polyolefin-based matrix polymer with inorganic filler particles distributed therein and inorganic particles dispersed also in the gas barrier layer from the liquid gas barrier composition. Also disclosed is a method for manufacturing the packaging laminate and a packaging container made from the packaging laminate.

  • Publication number: 20110204137
    Abstract: The present invention relates to a method for visualization of non-visible information on a packaging material to provide traceability. The method comprises the steps of: reading the non-visible information from the packaging material by means of a magnetic head reader, processing the non-visible information in a central processing unit together with additional new non-visible information, and printing an optional portion of the amount of combined non-visible information onto the packaging material as a traceability marking. The invention also relates to a device for carrying out the method and a packaging line with a filling machine making use of the device.

  • Publication number: 20110162326
    Abstract: A packaging laminate includes at least one material layer provided with magnetisable particles. A roller can be configured to apply crease line patterns on the packaging laminate while also applying magnetic fields for magnetising at least some of the magnetisable 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.

  • Patent number: 6315939
    Abstract: Stretch blow molded containers are made from a preform made of a plastic material suitable for stretch blow molding such as, e.g., PET. The preform is heated to a temperature suitable for stretch blow molding and is introduced into a mold. An explosive gas mixture is introduced into the preform with a stretching pressure and the preform is axially stretched with the help of a stretching rod. After stretching, the explosive gas mixture is ignited, the explosion creating a blowing pressure which presses the wall of the preform against the inner wall of the mold so as to impart to the container its definite form. Due to the temperature shock generated by the explosion, the inner surface of the container is simultaneously sterilized.

  • Patent number: 6260723
    Abstract: A package for flowable media and a snap lid which package and snap lid are both made from thermoplastic material, in which a collar-shaped head of the package surrounds a pouring aperture of the package, which collar-shaped head has a retaining ring on its outside, an inside annular surface, and an upper end having an edge with a snap catch, which upper end can be closed using the snap lid. The snap lid has a closing wall from which an annular sealing lip projects towards an inside of the package, and can be brought into contact with an inside surface of the edge in sealing engagement. The closing wall is provided with an outside catch for snap engagement with a snap catch of the edge of the head. The head of the package widens outwards and upwards at its edge, and both the inner surface of this edge and an outer surface of the sealing lip on the snap lid are curved convexly relative to each other. The invention also includes preforms for making the package of the invention.

  • Patent number: 5906279
    Abstract: A stack (31) of cup-shaped containers (2, 4, 6) coaxially inserted one inside another is described, each with a side wall (32) on one end of which a base (33) is arranged, and on the other end a flange (1), wherein the container (2, 4, 6) is composed of a flexible material and the flange (1) is substantially stiffer than the side wall (32) and the base (33). In order to make such a stack (31) more easy to manufacture and to take apart, it is provided according to the invention that apart from the outermost cup-shaped container (4), each inner container (2) is partially radially folded, and that the degree of folding gradually increases towards the innermost cup-shaped container (2).
