  • Patent number: 9676512
    Abstract: A forming device and method for use in a packaging machine of the type where packages are produced from a tube. The forming device comprises two opposing sealing elements between which the tube is arranged to be flat-laid and squeezed to heat the thermoplastic and obtain a first transverse seal of the tube. It further comprises two volume control elements. The forming device is characterized in that it is arranged to displace the first transverse seal off-center in relation a longitudinal axis of the first portion of the tube in a displacement direction essentially perpendicular to the first transverse seal to enable later shaping of a corresponding final package with a wall arranged with a predetermined angle of inclination in relation to the displacement direction. The invention also relates to a machine, a process and a packaging laminate.

  • Patent number: 9156576
    Abstract: An arrangement is provided to prevent emissions of hydrogen peroxide from a packaging machine forming sealed packaging containers from a packaging material web. The packaging machine has a sterilization portion comprising an inlet chamber, a peroxide bath and an aseptic chamber. The aseptic chamber is held at an overpressure while the inlet chamber is held at an underpressure during normal operation of the packaging machine. The peroxide bath functions as a seal between the inlet chamber and the aseptic chamber. A safety chamber placed in front of the inlet chamber is held at an underpressure to avoid peroxide emissions to the environment. The packaging material web will pass the safety chamber before going into the inlet chamber.
