Abstract
In a packaging machine 2 with a movable part 27, which can be moved toward a packaging 26 or a product to be packaged, and a carrier movable with the part 27 and connected to the part 27, the part 27 and/or the carrier consists of a magnesium alloy 28, for example Mg Ag3 Se2 Zr1 or Mg A19 Zn1. A magnesium alloy 28 has low mass, low moment of inertia, high capability to conduct heat, high heat capacity and good stiffness. It can also be used for heated, package-building elements, for example, a longitudinal sealing jaw 33 movable toward a foil tube 6, a cross-sealing jaw 16, 17 or a cutting knife 25. Relatively small forces are needed for moving a part 27 and/or a carrier 23 consisting of a magnesium alloy 28, which makes the packaging machine 2 less expensive to operate.
