`DATA STORAGE CARD AND METHOD FOR
`THE MANUFACTURE OF A DATA STORAGE
`CARD
`
`FIELD OF INVENTION
`
`This invention relates to a data carrier card, in particular a
`chip card and/or magnetic stripe card, and to a method for
`producing a data carrier card.
`
`BACKGROUND
`
`Data carrier cards are usually manufactured nowadays
`from plastic foils, for example by several foils being lami
`nated together to form a card body, whereby the card body is
`normally punched out of the foils and Subsequently processed
`further in order to provide on the card body a corresponding
`data storage means or data processing means, in particular in
`the form of a microchip or a magnetic stripe.
`In general, plastic foils can be produced by extrusion pro
`cesses whereina molten stream of plastic material is melted in
`an extruder and pressed through a nozzle to form the foil.
`In the print DE 10 2004 013 201 A1 there is described a
`so-called coextrusion process wherein at least two polymeric
`molten streams of different composition are merged to
`thereby produce foils having areas with different material
`properties.
`In the print GB 2 348 394 Athere is described a further
`process for coextrusion wherein a foil comprising longitudi
`nal strips of various colors is formed between a lower and an
`upper layer.
`In the production of conventional data carrier cards there
`exists the problem that areas with different material proper
`ties, such as Zones designed in different colors, must be pro
`duced in separate processing steps, e.g. by measures of print
`ing technology, which makes the production of Such data
`carrier cards elaborate.
`
`SUMMARY
`
`The object of the invention is therefore to form areas with
`different material properties in a data carrier card in a simple
`a.
`The data carrier card according to the invention comprises
`a card body comprising one or several foils, wherein the foil
`or at least one of the several foils is a coextruded foil which
`comprises at least two areas with different material proper
`ties. The invention is based on the finding that foils produced
`by coextrusion can be employed for data carrier cards in
`suitable fashion in order to form areas with different material
`properties, in particular different Surface areas. In this manner
`it is possible to omit separate processing steps for forming
`areas with different properties.
`The card body of the data carrier card according to the
`invention has, in a preferred variant, several Superposed foils
`which are laminated together or configured as a whole by
`coextrusion. At least one of the foils here is a coextruded foil,
`whereby the whole layer arrangement can also be formed by
`coextrusion, however, so that the layer arrangement can in
`this case also be equated with a single coextruded foil which
`has areas with different properties in the direction of the
`thickness of the foil and preferably also over the surface of the
`foil.
`In a further embodiment of the invention, the card body
`likewise has several Superposed foils, wherein at least a por
`tion of the foils are formed from one material over the entire
`Surface and are arranged on at least one side of the coextruded
`

`foil. In this manner it is possible to increase the stability of the
`card body. The foils formed from one material over the entire
`Surface can be transmissive or opaque foils, whereby trans
`missive is understood to mean both completely light-trans
`missive, i.e. transparent, and partly light-transmissive, i.e.
`translucent.
`In an especially preferred embodiment, the at least two
`areas of the coextruded foils or of at least one coextruded foil
`are formed from different materials. Likewise, the at least two
`areas can be formed from the same basic material with dif
`ferent additives. The various areas with different material
`properties can differ in particular in their optical properties.
`For example, at least one area of the at least two areas of a
`coextruded foil can be opaque and at least one other area of
`the at least two areas of the coextruded foil can be transmis
`sive, in particular transparent or translucent. The optical prop
`erties of the areas can also differ with regard to their polar
`ization properties. In particular, at least one area of the at least
`two areas can be polarizing, so that it only passes light with a
`predetermined polarization. In this manner it is possible to
`produce different optical effects in the cardbody in especially
`simple fashion.
`In an especially preferred embodiment of the data carrier
`according to the invention, at least one area of the at least two
`areas of the, or at least one, coextruded foil is formed from
`more elastic and/or more hardwearing material than at least
`one other surface area of the at least two surface areas of the
`coextruded foil. If the data carrier card is employed later for
`example in an electronic identification book for identification
`of a person, in particular an area of the, or at least one,
`coextruded foil that is located at the seam of the later identi
`fication book is more elastic than an area of the coextruded
`foil not located at the seam of the later identification book. In
`this manner a high stability of the identification book is guar
`anteed in an area where the relevant identification data are
`preferably located (i.e. remotely from the seam), whereby at
`the same time a good handling of the identification book upon
`turning of the pages is guaranteed by the elastic area at the
`SCall.
`The different areas of the, or at least one, coextruded foil
`can be formed from any desired plastics. Preferably there are
`employed for this purpose one or several of the following
`materials: polycarbonate, PET (PET polyethylene tereph
`thalate), PETG (PETG-polyethylene terephthalate glycol),
`TPE
`(TPE=thermoplastic
`elastomer),
`TPU
`(TPU-thermoplastic elastomer, urethane-based), polyole
`fins, PA (PA polyamide), PVC (PVC polyvinyl chloride),
`ABS (ABS-acrylonitrile-butadiene-styrene copolymer).
`In the data carrier according to the invention, the transitions
`between two neighboring areas of the, or at least one, coex
`truded foil can further be executed in any desired way, in
`particular in sharp and/or also Smooth manner, whereby the
`properties of the transition can also change along a transition.
`In an especially preferred embodiment of the data carrier
`card according to the invention, one or several coextruded
`foils each having at least one opaque area and at least one
`transmissive area are configured and/or arranged one over the
`other Such that the data carrier card has at least one transmis
`sive window and/or at least one transmissive window strip.
`This makes it possible to form a window area in a simple
`manner without additional processing steps. The window or
`the window strip can extend through the whole cardbody, but
`windows or window strips are also conceivable that do not go
`through the whole thickness of the card body but end at an
`opaque area of a foil.
`In a further embodiment of the invention, the coextruded
`foil or at least one coextruded foil comprises a plurality of
`

`alternating strips, for example longitudinal strips, with differ
`ent material properties. In particular, opaque strips and trans
`missive strips can alternate in the coextruded foil.
`In a further embodiment of the data carrier card according
`to the invention, at least a portion of Superposed coextruded
`foils with alternating opaque and transmissive strips are
`arranged such that the at least one window and/or the at least
`one window strip is formed by the arrangement. For example,
`at least a portion of superposed coextruded foils with alter
`nating opaque and transmissive strips can be arranged Such
`that opaque and transmissive strips of neighboring foils are
`Superposed in each case. That is, the opaque strip of one foil
`lies precisely on or under the opaque strip of another neigh
`boring foil, and the same applies to the transmissive strips.
`Likewise, at least a portion of Superposed coextruded foils
`can be arranged such that opaque and transmissive strips of
`neighboring foils are oriented so as to be offset and/or rotated
`relative to each other, in particular rotated by an angle of 90°.
`There are therefore formed preferably limited windows
`within the surface of the foil.
`The thickness of the card body of the data carrier card is
`between 80 um and 840 um, in a preferred variant of the
`invention. This guarantees a sufficient stability of the card
`body. In a further embodiment of the data carrier card accord
`ing to the invention, the, or at least one, coextruded foil is
`printed or provided with a lacquering at least on one side. In
`this manner it is possible to produce further optical effects.
`Besides the above-described data carrier card, the inven
`tion further comprises a method for producing such a data
`carrier card, wherein the card body of the data carrier card is
`formed by coextrusion of at least one foil such that the at least
`one foil has at least two areas with different material proper
`ties. The coextrusion is effected in particular with a multilayer
`noZZle of a coextrusion assembly and preferably at a tempera
`ture of substantially 230° C. and more, in particular at 250° C.
`In a further variant, one or several further foils are applied to
`at least one side of the coextruded foil by lamination, making
`it possible to form a multi-ply data carrier card. The produc
`tion method usually comprises further steps, in particular the
`punching of the cardbody out of the coextruded foil or out of
`40
`the multi-ply layer structure comprising coextruded foil and
`further foils, the application of a chip or a magnetic stripe and
`the like.

`body comprising a single plastic foil 2. Said foil is produced
`on the basis of a coextrusion process wherein several molten
`streams coming from different extruders are merged in a
`multilayer nozzle, so that there are formed in the foil different
`Surface areas from the various molten streams. The molten
`streams differ here in their material properties. In the embodi
`ment according to FIG. 1, a multiplicity of alternating longi
`tudinal strips 2a and 2b are formed by the multilayer nozzle,
`whereby the strips 2a and 2b in each case belong to the same
`molten stream of a corresponding extruder. The molten
`stream resulting in the strips 2a is based on an opaque poly
`meric material, which is indicated by the dotted cross section
`in FIG. 1 and all further figures. Between two strips 2a there
`is a strip 2b which comes from a molten stream of transparent
`polymer.
`FIG. 4 shows schematically a corresponding coextrusion
`assembly for forming the card body according to FIG. 1.
`Through the extruder EX1 there is produced a molten stream
`for forming the transparent strips 2b, as indicated by a corre
`sponding line L1. Further, through the extruder EX2 there is
`generated a molten stream for forming the opaque strips 2a,
`which is indicated by corresponding lines L2 and L3. The
`formation of the contiguous strips is effected with the help of
`a multilayer nozzle (not shown) having corresponding nozzle
`openings and feeds for the molten streams for forming the
`neighboring strips 2a or 2b. For reasons of clarity, only three
`neighboring strips 2 are shown in FIG. 4, whereby the foil
`cross section according to FIG. 1 is produced by multiple
`repetitions of alternating neighboring strips 2a and 2b.
`Coextrusion processes are generally known, so that a
`detailed description of such processes and corresponding par
`allel multi-nozzle extrusion apparatuses for carrying out such
`processes will be omitted. Nevertheless, the use of coextru
`sion processes for producing cardbodies comprising Surface
`areas with different material properties is not known from the
`prior art. The coextrusion preferably takes place at the tem
`perature of the molten streams of approx. 250°C. This results
`in a homogeneous foil without recognizable mechanical
`weak points or predetermined breaking points.
`FIG. 2 shows a second embodiment of a card body accord
`ing to the invention. Said card body 101 has, as in FIG. 1, a
`coextruded foil 2, which can be produced in the same way as
`the foil of FIG.1. Unlike the card body 1 of FIG. 1, however,
`two further foils 3 or 4 are now arranged above the foil 2,
`whereby the foils 3 and 4 in the embodiment of FIG. 2 are
`transparent and consist of the same polymeric material over
`the entire surface. The foils can, in one embodiment, be
`manufactured separately and Subsequently be laminated on
`the foil 2. The foils themselves are preferably likewise pro
`duced by extrusion. The use of further foils increases the
`stability of the card body. The individual foils can further
`more contain different formulation constituents, e.g. laser
`additives, security features, optical features and the like.
`Instead of applying the foils 3 and 4 by lamination, it is also
`possible to form the layer structure according to FIG. 2 in a
`single coextrusion step with an accordingly configured and
`controlled multilayer nozzle. A corresponding coextrusion
`assembly for carrying out such a coextrusion is indicated
`schematically in FIG. 5. There are now employed three
`extruders EX1, EX2 and EX3. The extruder EX1 produces
`the molten stream of the uppermost layer 4 and the molten
`streams of the transparent strips 2b, as indicated by lines L1'
`and L2. Through the extruder EX2 there is generated the
`molten stream for the middle transparent foil 3 (line L3'). In
`contrast, the extruder EX3 produces the opaque molten
`stream of the corresponding opaque strips 2a, as rendered by
`lines L4 and L5'. For reasons of clarity, only three of the strips

`the other areas. Those areas of material not located along the
`bending axis and thus requiring lower resistance can be pro
`duced from less expensive, less stable material. In this man
`ner the costs for production of the card body are reduced.
`As set forth above, the individual strips 2a or 2b of the foil
`2 according to FIGS. 1 to 3 can beformed from the same basic
`polymeric material with different additives. For example, for
`the opaque areas 2a corresponding dyes can be added. Like
`wise, the transparent areas 2b can be configured so as to be not
`completely transparent, but only partly transmissive, i.e.
`translucent, whereby said areas can optionally also be dyed or
`pigmented. Likewise, the individual strips can have polariz
`ing properties. Optionally the strips 2a and 2b can also consist
`of different polymeric materials. Particularly preferably,
`there can be used as plastic materials for the individual strips
`of the foil 2 or also for the foils 3 and 4 the following plastics,
`alone or in combination: poly-carbonate, PET, PETG, TPE,
`TPU, polyolefins, PA, PVC and ABS.
`Further effects can be achieved by configuring the corre
`sponding transitions between the different materials suitably
`depending on the case of application, e.g. Smoothly or
`sharply. The foils 3 and 4 according to the embodiments of
`FIG.2 and FIG.3 can optionally be dyed to thereby create e.g.
`translucent applications or to produce colored gradations in
`transmitted light.
`In an especially preferred embodiment of the invention,
`card bodies are formed from a plurality of coextruded foils
`with different surface areas. This is indicated in the embodi
`ment according to FIG. 7, whereby in this example two iden
`tical coextruded foils 2 with alternating opaque strips 2a and
`transparent strips 2b are arranged one over the other. The
`individual coextruded foils correspond in structure to the
`coextruded foil 2 according to FIG.1. By offset or rotation of
`the layers relative to each other it is possible to produce card
`bodies with transparent windows. According to FIG. 7 such
`transparent windows arise through the strips of the lower foil
`being rotated by 90° relative to the strips of the upper foil. In
`the overlap areas between the transparent strips of the lower
`and upper foils there then arise corresponding square win
`dows.
`Optionally, the surface of the card body can be printed in
`subareas. FIG. 8 shows a card body 301 with printing. The
`card body 301 comprises a plurality of foils (not individually
`shown) with Superposed opaque and transparent areas. This
`results in opaque strips 2a extending through the total thick
`ness of the card body, and transparent strips 2b extending
`through the total thickness of the card body. The card body
`301 is provided with a corresponding print 5, which is applied
`in the opaque area2a in the embodiment of FIG.8. The print
`can optionally also be configured Such that it is located only in
`the transparent, or in the transparent and opaque, area of the
`card body. In particular, the printing can be configured Such
`that corresponding window areas of predetermined size result
`on the transparent Strips.
`FIG. 9 shows a further embodiment of a card body 401
`according to the invention wherein there are configured win
`dow areas 6 which extend only partly into the card body and
`not therethrough. Such recess-like window areas 6 are of
`advantage in particular when a card body 401 is to be pro
`vided later with an MLI (multiple laser image) or a CLI
`(changeable laser image). In the area of the windows 6 there
`can then be provided a greater layer thickness for receiving an
`MLI or a CLI. This in turn permits the configuration of the
`MLIs or CLIs with greater lens radii, thereby simplifying the
`production of the MLIs or CLIs. A cardbody as shown in FIG.
`9 can be produced for example by a multilayer structure
`according to FIG. 7. The generation of window areas of
`
`5
`of the foil 2 are rendered. The formation of the molten stream
`for the uppermost foil 4 according to the line L1 is optional
`and might be omitted, so that only a single additional foil 3 is
`formed on the foil 2. According to FIG. 5 there is realized a
`coextrusion process which produces different molten streams
`not only over the surface in the horizontal direction, but also
`in the direction of the thickness of the layer structure. The
`coextrusion thus also comprises the simultaneous production
`of several different foil layers.
`FIG.3 shows a third embodiment of a cardbody according
`to the invention in a cross-sectional view. The card body 201
`of FIG. 3 corresponds substantially to the card body 101 of
`FIG. 2. However, the foil 2 with the individual strips 2a and 2b
`is now arranged between the two transparent foils 3 and 4.
`This structure also obtains an elevated mechanical stability of
`the card body. As in FIG. 2, the foils 3 and 4 can be manu
`factured separately, in particular by extrusion, and Subse
`quently be laminated on the coextruded foil 2. The layer
`structure of the foils according to FIG.3 can, however, also be
`produced in a single coextrusion step. An extrusion assembly
`provided therefor is rendered schematically in FIG. 6. The
`assembly of FIG. 6 corresponds largely to the assembly
`according to FIG. 5. Via an extruder EX1 there is produced
`the molten stream for forming the upper foil layer 4 and the
`transparent strips 2b of the foil 2, as indicated by lines L1" and
`L2". The extruder EX2 generates the molten stream of the
`opaque layers 2a of the foil 2 (lines L3" and L4"). In contrast
`to the assembly of FIG. 5, there is now produced through the
`extruder EX3 a lower molten stream under the foil 2 for
`forming the foil 3, as indicated by the line L5'. The production
`of the different foil areas in the vertical and the horizontal
`directions is again effected here through an accordingly con
`figured and controlled multilayer nozzle having a multiplicity
`of nozzle openings.
`The card bodies according to FIG. 1 to FIG.3 produced by
`the above-described methods have typical thicknesses of 80
`um to 840 um, whereby thicker or thinner foils can be chosen
`depending on the case of application, and the thicknesses of
`the particular foil layers in a card body can also differ from
`each other.
`Through the card-body foil production according to the
`invention based on coextrusion it is possible to form different
`variants of variously configured data carrier cards in a simple
`manner. In particular, corresponding additives in the indi
`vidual different molten streams of the extruders can be used to
`produce different locally limited effects in the card bodies,
`such as light effects, color shift effects and the like. Further
`light effects can be obtained by corresponding printing of the
`foils. The individual materials constituting the strips of the
`foil 2 according to FIG. 1 to FIG. 3 can derive from the same
`basic material, but with different additives added for strips 2a
`and 2b. Likewise, it is possible to employ completely differ
`ent polymeric materials for the individual strips 2a and 2b.
`The foils 3 and 4 according to FIG. 2 and FIG. 3 can also
`optionally consist of different materials or of materials with
`different additives.
`With the coextrusion process according to the invention it
`is possible to produce in particular card bodies for an elec
`tronic passport document. The cardbody is formed here from
`a material that is flexible in the seam area of the passport to
`thereby guarantee a good turning of pages in the passport
`document. In contrast, the area of the card body on which the
`personal data of the passport are located is formed by a
`material that has a certain stiffness to thereby increase the
`stability of the document. Likewise, in cards with bending
`axes, the areas along the bending axis can be produced, by
`means of coextrusion, from more hardwearing material than

`of the width of the transparent or opaque strips of the foil 2.
