Definitions

  • the present invention generally relates to the manufacturing of a laminated paper product with integrated electronics. More particularly, the present invention concerns a process for improving the front to back registration of a laminated paper product comprising integrated electronics.
  • the paper product with integrated electronics must be planar with homogeneous thickness and the surface of the paper product must be printable with high quality images.
  • EP3269558 entitled “A manufacturing process for a laminated paper product” for instance describes the manufacturing of a laminated paper product with integrated electronics.
  • the method described in EP3269558 comprises the steps of printing and cutting a first paper, printing and cutting a second paper, and forming a paper product by providing planar electronics between the first paper and the second paper when the first paper and the second paper are overlaid on top of each other and glued to each other.
  • a drawback of the manufacturing method described in EP3269558 is that the pre-cut second paper must be very precisely and individually aligned with respect to the pre-cut first paper when forming the paper product such that the front to back registration of the final paper product is guaranteed. If the second paper is not suitably aligned with respect to the first paper, for example if the second paper is rotated with respect to the first paper, the front to back registration of the final paper product is poor. The alignment operation must also be repeated for all the second papers and the corresponding first papers. This is a very sensitive alignment which must be accurately controlled to maximize the quality of the final paper product. The manufacturing method described in EP3269558 is therefore too slow to be developed at large scale.
  • EP3269558 after overlaying the second paper on top of the planar electronics and the first paper, a heated roll applies heat and pressure to the three aligned layers to active the glue. There is a risk that the planar electronics are damaged by the temperature elevation and/or by the pressure applied on the three overlaid layers.
  • European Patent Application EP0858061 entitled “A safety label and a device for its manufacture” describes a method for manufacturing labels with integrated electronics and uniform thickness.
  • the manufacturing method of EP0858061 is developed to produce labels comprising a radio-frequency tag fitted between two sheets of cardboard.
  • a continuous roll of printed cardboard is provided with the front and the back of the label such that they form a single body.
  • a labelling machine positions the radio-frequency tags over the non-printed side of the printed cardboard.
  • Two rollers perpendicular to the advance of the continuous printed cardboard cause the folding of the printed cardboard along a longitudinal line such that both halves of the continuous printed cardboard are overlaid on top of each other and glued together.
  • EP0858061 The manufacturing method described in EP0858061 is developed for cardboard with a much smaller substance than those used in manufacture of conventional labels, as described on page 3, lines 27-31 of EP0858061 .
  • a drawback of this manufacturing method is therefore that it requires working with rolls of flexible substrate which can easily be folded.
  • the manufacturing method of EP0858061 is not compatible with substrates and paper sheets which are thicker and more rigid than cardboard for the manufacturing of labels, such as for example substrates and paper sheets used to manufacture cards or playing cards or tickets, PVC cards, etc.. It remains very challenging to feed a roll of continuous thicker substrate to the two rollers of EP0858061 and to fold the continuous thicker and rigid substrate along a longitudinal line while ensuring a satisfying front to back registration of the final paper product.
  • the manufactured labels of EP0858061 must be submitted to pressure rollers which press down the two halves of the labels together and which submit the manufactured labels to an elevation in temperature.
  • the applied heat and pressure risk damaging the radio-frequency tags and there is a risk the tags do not function properly anymore.
  • the above defined objectives are realized by a method for manufacturing a laminated paper product with integrated electronics, wherein the method comprises the steps of:
  • the manufacturing method according to the present invention results in an improved front to back registration of laminated paper products.
  • a laminated paper product is produced with very precise alignment of the two flaps with respect to each other when the two flaps are overlaid on top of each other by folding a strip along its fold line.
  • the use of a strip comprising both the front and the back of the laminated paper product lowers the risk of a possible misalignment of the front with respect to the back of the laminated paper product due to a rotation of the paper sheet when overlaying the front on top of the back of the laminated paper product when the front and the back of the laminated paper product are manufactured from a paper sheet which would comprise several strips.
  • the laminated paper product has a uniform thickness of at most 7 millimeters, preferably at most 6 millimeters, enabling to maintain the tactile properties of existing paper cards or cardboard cards that have no electronics integrated.
  • both flaps overlaid to form the laminated paper product are printed next to each other on the paper sheet.
  • both flaps are printed so close to each other on the paper sheet that both flaps have similar thicknesses and similar fiber structure from the paper sheet as both flaps are printed from the same paper sheet. This way, there is very little deviation in the thickness and fiber structure of both flaps when both flaps are overlaid to form the laminated paper product.
  • the laminated paper product is therefore well balanced, and its thickness is uniform over the whole product.
  • both flaps will be printed on similar fiber structures.
  • the printing display and the printing quality of both sets of image pairs on the two flaps of a laminated paper product manufactured according to the present invention will be more similar than when the laminated paper product is manufactured according to a manufacturing process known from the prior art by overlaying and gluing the front and the back of a laminated paper product on top of each other, wherein the front and the back were printed on two separate strips formed on two different paper sheets that are then overlaid and glued together.
  • both flaps fabricated from a strip will demonstrate the same mechanical resistance and the same folding behavior as both flaps are manufactured from the same paper sheet. For example, in presence of elevated humidity in the environment of the laminated paper product, both flaps manufactured from the same paper sheet will deform the same way. This will avoid creating a warping or bending effect that is caused by humidity change over time of a stack of playing cards.
  • the printing speed with the method according to the present invention is typically printing 8000 paper sheets per hour.
  • the die cutting speed with the method according to the present invention is typically die cutting 3000 paper sheets per hour.
  • the strip folding speed with the method according to the present invention is folding 5000 strips per hour.
  • pre-cutting strips of the substrate or of the paper sheet and overlaying both flaps of each strip on top of each other allows using thicker and more rigid substrates and/or thicker and more rigid paper sheets to form laminated products, without rotation of one flap with respect to the other and while guaranteeing a good front to back registration of the final laminated paper product.
  • another technical advantage when working with die cut strips is the maximization of the use of the surface of the paper sheet for the manufacturing of the laminated paper product.
  • the strips can be die cut so as to minimize a margin with respect to the dimensions of the paper sheet, thereby reducing waste of paper sheet.
  • the paper sheet according to the present invention for example comprises a longitudinal direction along which one or more of the respective fold lines of the strips are extending.
  • one or more image pairs are printed on the printing surface of the paper sheet such that a respective fold line separates the image pairs into two sets and such that the respective fold line extends along the longitudinal direction of the paper sheet.
  • the paper sheet for example comprises a longitudinal direction, and one or more of the respective fold lines of the strips are extending along a traverse direction traverse to the longitudinal direction of the paper sheet.
  • one or more image pairs are printed on the printing surface of the paper sheet such that a respective fold line separates the image pairs into two sets and such that the respective fold line extends along the traverse direction of the paper sheet.
  • the adhesive for example becomes active when applying heat and/or pressure.
  • the adhesive may be provided before or after the printing and cutting.
  • planar electronics is not submitted to an elevation of temperature through heating of the overlaid flaps, which guarantees the integrity of the planar electronics.
  • the risk of damaging the planar electronics during manufacturing the laminated paper product is therefore minimized with respect to methods know from the prior art which require submitting the planar electronics to an elevated temperature to cure an adhesive provided between the front and the back of the paper product.
  • the planar electronics is submitted to a slight elevation of temperature when heating the overlaid flaps and applying minimal pressure on them in order to cure the adhesive. In this case, the temperature is chosen adequately as to guarantee the performance of the planar electronics is not jeopardized.
  • the overlaid flaps are laminated by reactivating the adhesive through heat and minimal pressure applied by for example a heated roll system.
  • the temperature of this heated roll system is preferably kept below 120°C to avoid damaging the ink printed on the paper sheet and the planar electronics in the laminated paper product.
  • the lamination process is applied as a last step. No printing of the laminated product must be done afterwards, further reducing the risk for damaging the planar electronics and consequently improving the overall yield of the produced laminated paper product with integrated electronics.
  • the overlaid flaps undergo limited pressure in order to securely glue the flaps together while preserving the physical integrity of the planar electronics integrated in the laminated paper product.
  • the overlaid flaps are submitted to a pressure of maximum 4 bar distributed over one or more rolls.
  • Planar electronics in the context of the present invention for example comprise a RFID inlay.
  • a RFID chip is typically for example 60 ⁇ m thick, and the inlay on the RFID chip itself is usually for example 100 ⁇ m thick.
  • the planar electronics comprise printed electronics.
  • the planar electronics according to the present invention comprise one or more Near Field Communication chips, also referred to as NFC chips.
  • the paper sheet has a thickness comprised between 100 micrometers and 3000 micrometers.
  • the paper sheet preferably has a thickness of 170 micrometers
  • the paper sheet preferable has a thickness of 300 micrometers.
  • the paper sheet has a paper weight comprised between 80 and 3000 grams per square meter.
  • the paper sheet preferably has a paper weight of 175 grams per square meter.
  • the paper sheet preferable has a paper weight of 275 grams per square meter.
  • printing image pairs corresponds to printing a set of images from the image pairs on one of the flaps and to printing the set of corresponding images from the image pairs on the other flap such that each of the image pairs is divided by the respective fold line.
  • each flap of the pre-cut strips comprises half of the image pairs printed on the strips.
  • providing planar electronics on the opposite surface of at least one of the flaps corresponds to aligning the planar electronics on the opposite surface of at least one of the flaps such that the planar electronics coincide with the images on the printing surface of the respective flap.
  • planar electronics are aligned with respect to the images on the printing surface of the respective flap. This way, the planar electronics are encapsulated in the adhesive between the two flaps on the laminated paper product. In other words, the planar electronics is surrounded on all sides by adhesive when the two flaps are overlaid on top of each other. This protects the planar electronics from the exterior environment, thereby guaranteeing its integrity.
  • each of the image pairs comprises a front side image of a laminated paper product and a corresponding back side image of a laminated paper product.
  • the laminated paper product is a playing card and each of the image pairs comprises a front side image of a playing card and a corresponding back side image of a playing card.
  • the laminated paper product is a card, a ticket, a leaflet, etc. and each of the image pairs comprises a front side image of respectively a card, a ticket, a leaflet, etc..
  • folding each of the strips along the respective fold line corresponds to overlaying the front side images and the corresponding back side images onto each other, thereby forming pairs of images overlaid onto each other.
  • punching the laminated paper product out of the overlaid flaps corresponds to punching a pair of images overlaid onto each other out of the overlaid flaps, thereby obtaining the laminated paper product.
  • the laminated paper product is for example a playing card and punching the laminated paper product out of the overlaid flaps corresponds to punching a pair of playing card images overlaid onto each other out of the overlaid flaps, thereby obtaining the playing card.
  • the laminated paper product is for example a ticket and punching the laminated paper product out of the overlaid flaps corresponds to punching a pair of playing card images overlaid onto each other out of the overlaid flaps, thereby obtaining the ticket.
  • Punching the laminated paper product out of the overlaid flaps allows a very precise cut of the laminated paper product out of the overlaid flaps.
  • the cut edges along the periphery of the laminated paper product are straight and clean.
  • the cut edge of one flap is aligned with respect the cut edge of the corresponding other flap along a traverse direction to the planed formed by the laminated paper product.
  • the method further comprises trimming edges of the laminated paper product after punching the laminated paper product out of the overlaid flaps.
  • the edges of the laminated paper product produced through the method are trimmed with a cutter after the lamination process when the card edges are too rough.
  • the method further comprises the step of printing opacifying images on the opposite surface of the paper sheet before die cutting the strips from the paper sheet.
  • the method further comprises the step of applying colored adhesive on the opposite surface of the flaps in order to improve the opacity of the printing surface of the paper sheet.
  • the method further comprises the step of aligning the opacifying images with respect to the images such that the opacifying images coincide with the images on the printing surface of the respective flap.
  • applying the adhesive on the opposite surface of at least one of the flaps corresponds to applying hot melt glue on the opposite surface of at least one of said flaps.
  • both flaps are securely fixed to each other when overlaid on top of each other, thereby ensuring the planar electronics does not detach from the opposite surface of at least one of the flaps.
  • any other type of suitable glue may be applied to the opposite surface of at least one of the flaps.
  • applying the adhesive on the opposite surface of at least one of the flaps corresponds to applying hot melt glue on the opposite surface of both flaps.

  • the faster the strip is folded the better the adhesion between the two flaps.
  • the hot melt glue can be cured through passive cooling.
  • the overlaid flaps are laminated by reactivating the adhesive, for example the hot melt glue, through heat and pressure applied by for example a heated roll system.
