  • Sealer 200 first fill their interior with the desired gas mixture, so that the gap 16 is filled with the desired gas mixture.
  • the partial vacuum can be carried out, so that the volume of the intermediate space 16 is provided with the desired gas mixture.
  • a Geschirrritt 1 which preferably consists of a magnesium oxide porcelain.
  • the Geschirrritt is designed in particular as a plate and preferably has a total length of about 330 mm (+/- 15 mm) and a
  • the Geschirrwent 1 is in particular for the insertion and transport of the packaged with the foil plate in standardized
  • At least one further container may be positioned on the dish unit.
  • a jug or the like may be provided, which for filling with sauces or small
  • an adhesive bond is used which, in particular, provides an adhesive area 8 on an elevation 19 on or in the edge portion 4.
  • the adhesive area 8 is formed circumferentially and continuously and is in particular rounded at the corners, so that the adhesive can be applied as a sealing material uniformly and sealable.
  • the adhesive used preferably has a high stability and in particular a viscosity of at least 1500 millipascal seconds at a
  • edge portion it is possible that a decorative edge is provided in the edge portion. But it is also possible that the plate is formed without decorative edge.
  • a PET film is provided for sealing the food and / or at least partially prepared menu components, in particular also
  • the film has a correspondingly adapted surface tension of at least 38 mN / m and in particular 42 or 43 or 44 mN / m.
  • the surface tension of the film used is greater than that of the plate.
  • at least the underside of the PT film used is at least partially treated by a surface treatment.
  • a corona treatment is performed.
  • the food-facing side of the surface treatment is subjected.
  • the dose to be introduced in corona treatment is the specific input of electrical energy into the moving foil web.
  • the adhesive behaves in such a way that it always tends towards the higher surface tension.
  • Corona treatment must always be aligned at the required level to maximize the subsequent adhesion of the food so covered to the underside of the PET film.
  • the application of the adhesive to the Geschirrwent 1 is carried out with an adhesive application machine, the adhesive application machine can have both fixed elements and orbiting elements and nozzles.
  • a rotating element is taken into account by shearing a so-called crumb formation
  • the adhesive Hafthotmelt adhesive is preferably applied with a clearly specified amount and temperature.
  • the tool does not touch the tableware unit 1.
  • the pressure can be effected for example by gas pressure, in which a gas mixture is blown onto the film. This prevents the plate from being damaged.
  • the invention provides an advantageous tableware with food arranged on the body covered by a foil, and an advantageous method of sealing is provided.
