Definitions

  • the invention relates to a cover laminate for plastic cards.
  • offset printing processes are used in combination with screen printing processes, whereby novel digital printing processes in the form of the INDIGO or XEIKO process as well as the various forms of inkjet printing technology can be used.
  • Low-price card systems and identification cards with a low lifespan requirement and / or low security requirements are often only printed on the surface and, if appropriate, provided with an additional coating in a printing process and / or coating process by means of liquid transparent lacquers for the purpose of surface protection.
  • thermoplastic plastic films are attached to the surfaces above the graphically designed films, depending on the manufacturing process, these films are added to a press package in multiple uses and in a typical multi-day transfer laminating process lead to complete cards which are then to be punched into individual cards.
  • identification cards preferably chip card systems
  • graphically designed foils are inserted fully automatically and individually in the respective cavities of the injection mold and back-injected.
  • the corresponding graphically designed foils lie with their printed image on the outside of the cards and are therefore not well protected against scratching or general damage.
  • contactless or hand-held chip cards, or so-called hybrid cards are being produced to an increasing extent, consisting of a combination of these card systems.
  • Non-contact chip card systems are high-quality card systems which are often intended for use over several years or for multiple daily use and must therefore have a high resistance to scratching or general damage to the graphic surface design.
  • DE 33 41 115 A1 discloses an identification card made of a laminate of interconnected, in particular thermoplastic, films, which contains a substrate with electronics comprising contacts, conductor tracks and at least one integrated circuit, and preferably a magnetic track arranged on the front of the card has an area for embossing divided into several lines running parallel to the magnetic track and to the card's longitudinal edges.
  • the aim of the invention is now to simplify the production of such cards and to ensure during the production, in particular of injection-molded cards, that the number of steps required for the completion is kept to a minimum.
  • the invention consists essentially in the fact that the cover laminate is formed from two pre-pressed layers, a printed opaque or white layer being pressed with a further transparent layer with the interposition of an adhesive. Because a cover laminate formed from pre-pressed layers is used, it can be made resistant to the effects of the injection molding process on printing inks, so that a cover laminate that has already been printed and finished can be used immediately.
  • usable cover laminates are produced inexpensively and simply with a minimum of production steps, which are used for novel card systems with high demands on the abrasion resistance of the graphic Design can be used and can also be used for the laminated technical production of card systems as well as for the production by means of injection molding, the design advantageously being such that the transparent layer has 30 to 70% of the layer thickness of the printed layer.
  • the design is particularly advantageously such that the pressed cover laminates have a thickness in the range from 70 to 200 ⁇ m, as a result of which the overall thickness is kept very small.
  • a particularly simple structure provides that the printed layer has a layer thickness of 80 ⁇ m to 100 ⁇ m, the transparent layer being approximately 50 ⁇ m thick.
  • Such a cover laminate can advantageously contain an internal magnetic strip in particular, in order to enable additional functions, with the advantage of a long service life and if the magnetic strip is arranged on the inside of the transparent cover films and is thus used internally in the cover laminate The result is a higher resistance of the magnetic strip in use.
  • the design is advantageously made such that the transparent layer consists of laser-writable plastic.
  • the white or opaque layer primarily increases the distance of the printed plane from hotter zones during production, and additional mechanical protection is provided by the transparent cover layer.
  • the respective temperature and resistance to deformation can be coordinated with one another by choosing suitable plastics, so that subsequently card structures critical for personalization information and also relief printing or the like can be used. are possible without damaging the print image.
  • the printing film sides or the cover laminate Pages that face the inner part of the card can also be coated using screen printing inks in order to achieve a high adhesive bond to the injection molding compound when using different plastic materials.
  • a possible coating system is based on an aqueous polyurethane dispersion, it being possible to use a long-chain aliphatic polyurethane system which is in turn applied by means of screen printing and thus ensures a high adhesive bond between the cover laminate and the injection molding compound or card core.
  • the temperature resistance of the cover laminate should, of course, be chosen so that a plastic mass introduced in the injection molding does not lead to thermal overloading of the cover laminate neither when it is inserted between cover laminates nor when it cures. Furthermore, for the loose encapsulation of chips, chip modules together with the associated antennas for contactless transmissions, the thermal and mechanical durability of the cover laminate should be sufficient to permit hot pressing with the material of the card core.
  • the pressed cover laminates preferably have a heat resistance of greater than 120 ° C.
  • An even higher temperature resistance of the cover laminates preferably greater than 135 ° C., creates even greater security, so that a plastic mass introduced in the injection molding does not lead to thermal overloading of the cover laminate neither when inserting between cover laminates nor during curing or solidification.

  • the graphically designed sheets are connected with transparent plastic sheet sheets 1 in a lamination process to form so-called cover laminates 3, 4.
  • the card core is labeled 5.
  • a transparent plastic film 1 serves as an overlay film.
  • These transparent overlay foils are optionally applied to the inside with thermally activatable hot melt adhesives 6 by means of screen printing, PVC-h, ABS, PET, PMMA up to PC as well as mixtures being able to be used as materials.
  • the magnetic strip introduced is designated by 15, reference numeral 7 represents the graphic design applied.
  • the two pre-assembled films 1 and 2 are connected to the cover laminates 3, 4 by means of a laminating process, typically in multi-storey transfer presses. This can take place in the usual multiple-use form and a renewed collation of the various layers 3, 4 as cover laminates and the further layers 13, 14, as shown in FIG. 4, the respective cover laminates 3 in this case already having a composite.
  • the cover laminates 3, 4 prefabricated in this way are usually punched optoelectronically into individual cover laminates and, for example, fed to an injection molding machine with injection molds 8, 9 and cavities 10, 11 from a magazine.
