  • a heat shrink film in the form of a heat shrink film jacket is placed around a stack of goods, wherein the heat shrink film coat protrudes with a circulating H societyschrumpffolienteil Scheme over the top of the stack for Oberschrumpf Struktur upper side. Further located a cover sheet on the top surface of the stack. The heat shrink film portion is first folded over so that it rests substantially flat on the lid sheet. This can be done in a separate machine.
  • the heat-shrinkable film portion may, for example, have been fixed in the region of at least one corner by spot welding, so that the still unthreaded heat-shrinkable film jacket does not slide down during transport of the stack.
  • spot welding Such a local welding in the region of the top to protect against slipping down can also be done by a horizontally oriented and vertically movable welding bar.
  • the four side surface portions of the heat shrink film jacket are shrunk by moving the stack through two vertically oriented heaters.
  • the disadvantage here is that shrinks during shrinkage and subsequent cooling of the heat shrink film coat not only in the longitudinal direction, but also in the transverse direction. In this case, in particular in the region of the long sides of a stack of goods, half-moon formation occurs, since here the heat-shrinkable film jacket pulls up due to transverse shrinkage.
