  • the substrate can be printed with all known printing processes, e.g. Book, offset, flexo, screen, Helio and copper intaglio printing.
  • the choice of which printing process is used depends on the desired print quality, on the respective technical conditions and the number of copies.
  • Flexographic printing also called aniline or rubber printing

  • the method is carried out in such a way that the inward-facing sealing layer by means of a Printing method is attached to the carrier material, the print image to the Shoulder area of the container corresponds.
  • a method for producing cover material according to the present invention is preferred where the inward-facing sealing layer and the outward-facing printing in be applied to a printing unit by printing the cover material on both sides.
  • the present invention also relates to the use of cover material made of a carrier material with, based on a container to which the lid material is applied, after outside-facing printing and an inward-facing sealing layer, whereby the sealing layer on the inside in the form of a printed image that covers the shoulder area of the container corresponds, is attached to the carrier material and the printed image on the shoulder area corresponds to a container, for closing by sealing the container with the corresponding shoulder area.
  • FIG. 1 shows, by way of example and schematically, a cup 1 made from side wall 2, bottom 3 and the upper edge, which forms the shoulder 4, after the cup 1 has been filled for example with a food or a drink, such as yogurt, jam, Dried fruit, a chocolate preparation or another dessert or with Drinking water or fruit and vegetable juices, the cup 1 is covered with the lid 10 and the lid 10 is sealed onto the cup 1 along the shoulder 4.

  • the sealing layer of primer 8 and sealing wax 9 is applied only or essentially only at those locations on the carrier 5 which come into contact with shoulder 4. This is shown schematically by the dash-dotted lines indicated. For the present example, this would mean that the sealing layer 8,9 has been printed in a ring on the carrier 5. It goes without saying that that Print image of the sealing layer from the shoulder area 4 of the cup 1 may differ slightly. For example, with a very wide shoulder 4, the printed image of the sealing layer 8.9 be narrower, e.g.

  • the present cover material has the advantage of being extremely economical with the starting materials to deal with, especially by using the primer or adhesion promoter and sealing wax only sparingly is used where it is actually needed.
  • the primer or coupling agent is used in amounts of 0.2 to 30 g, preferably 3 to 20 g, per square meter and the sealing wax in quantities of 0.5 to 30 g, preferably 1.5 to 20 g, per square meter and in particular applied with 6 to 10 g per square meter.
  • the primer, resp. Adhesion promoter and the sealing wax usually for processing in the Printing machine must be absorbed in a solvent, the amount is reduced on the solvent to be evaporated considerably. This is expressed both in energy requirements and also in the amount of solvent.
  • the present procedure is further below advantageous because the production of the lid material is one machine less needed.
  • the sealing layer does not have to be applied separately as a layer or film, but can be applied in the same operation and occasionally in the application of the printed image same printing unit, can be applied.
