  • each tray comprises several different packaging items, for example meat, vegetables and/or pasta, rice or the like, which are most preferably filled in sequence.
  • the deep drawing of the trays in the forming station is preferably done by negative pressure.
  • the bottom film is heated prior to the heating station, more preferably, the bottom film is heated uniformly.
  • the bottom film has a temperature between 150 to 170°C during the forming, preferably deep drawings of the trays into the film.
  • the inventive packaging comprises heating means which heat the film, so that a uniform temperature in the bottom film can be achieved. This can be achieved by one or more roll(s) around which the bottom film is wound and which are heated.
  • the inventive packaging machine comprises means to remove the packages from the packaging machines.
  • these means are vaccuum cups with which, more preferably each package can be removed individually.
  • the inventive packaging machine comprises means to reduce the packages from multiple rows to one row. This preferred embodiment of the present invention has the advantage, that the transfer of the packages to an autoclave are simplified.
  • the packaging machine comprises identification means which identify packages which have an unacceptable filling standard.
  • An unacceptable filling standard according to the present invention is either a filling standard which is too high or too low.
  • a rim which is polluted with the packaging item is also a package with an unacceptable filling standard according to the present invention, because this could have a negative impact of the sealing of the lid to the trays.
  • This unacceptable filling standard is identified by identification means, for example a camera or any other sensor that is capable of detecting such an unacceptable filling standard.
  • Packages which comprise an unacceptable filling standard are preferably marked.
  • This mark is identified preferably by the same or other identification means and these packages are sorted out of the production process after the packages have been cut out of the bottom film. This could be, for example, done with a robot which receives its signal from the identification means which recognizes the mark on the tray. Such a mark could be, for example, printed on the folds package.
