Definitions

  • the present invention relates to a shrink tunnel for heat shrinking of film according to the features of the preamble of claim 1.
  • the prior art discloses methods and devices for packaging articles (packaged goods) which use a shrink film as the packaging wrapper for the articles.
  • This shrink film is usually provided as a continuous material on rolls.
  • the shrink film is separated within the packaging device according to the container dimensions.
  • the foil blanks are then wrapped around the articles by means of a wrapping system within the device.
  • the containers are then transported through a shrink tunnel. In the shrink tunnel, the wrapped articles are exposed to warm air, which shrinks the shrink film so that it conforms to the articles and the finished shrink packages are formed.
  • a shrink tunnel can also be used to apply shrink labels to containers. Shrinkage quality and energy consumption play a major role in these processes.
