Definitions

  • the present disclosure relates, at least in part, to multi-layer sheets and cards that are manufactured from these sheets.
  • Laminated sheets and cards are used in a variety of applications, such as financial transaction cards (e.g., credit or debit cards, phone cards, gift cards, loyalty cards, etc.), security cards (e.g., identification cards), and the like.
  • financial transaction cards e.g., credit or debit cards, phone cards, gift cards, loyalty cards, etc.
  • security cards e.g., identification cards
  • Some known sheets and cards may be formed from multiple layers of plastic based substrates, adhesives and coatings, among other layers.
  • the cards also may include printing, graphics, and or other features.
  • Some cards are desired to have a core layer that is a different color from films disposed on opposite, visible sides of the core layer. Different colors may be used to represent or correspond to logos, color schemes, or the like, of suppliers or purveyors of the cards. But, due to the thin dimensions of the cards, certain combinations of colors may be different. For example, cores formed from dark colors may bleed through or change the appearance of lighter colors on the surface films. As a result, the final product may not have the desired colors or appearance.
  • a method (e.g., for manufacturing an extruded card assembly) includes extruding a sheet of a core layer for a card assembly, co-extruding a sheet of a blocking layer for the card assembly, and bonding the sheet of the core layer and the sheet of the blocking layer.
  • the card assembly can be separated (e.g., cut, punched, or the like) from the sheet of the core layer and the sheet of the blocking layer that are bonded together.
  • the sheet of the blocking layer is formed from a color that prevents the sheet of the core layer from being visible through the blocking layer in the card assembly.
  • bonding the sheet of the core layer and the sheet of the blocking layer includes coupling the sheet of the blocking layer to the sheet of the core layer without use of an adhesive material between the sheet of the core layer and the sheet of the blocking layer.
  • the first blocking layer, the core layer, and the second blocking layer are extruded during a common time period.
  • bonding the sheet of the core layer and the sheet of the blocking layer includes fusing the sheet of the blocking layer to the sheet of the core layer.
  • the first blocking layer, the core layer, and the second blocking layer are extruded during a common time period.
  • a card assembly in another embodiment, includes a core layer having opposite first and second sides, and a blocking layer having opposite first and second surfaces.
  • the second surface of the blocking layer can be bonded to the first side of the core layer such the first surface of the blocking layer is visible.
  • the blocking layer can have a thickness of no more than two mils while preventing color of the core layer from being visible through the first surface of the blocking layer.
  • the blocking layer is formed from a color that prevents the core layer from being visible through the first surface of the blocking layer.
  • the overlayer layer is a first blocking layer, and also including a second blocking layer on an opposite side of the core layer than the first blocking layer.
  • Figure 1 is a side view of an extruded card assembly formed in accordance with one embodiment
  • Figure 3 schematically illustrates an extrusion system used to form a sheet of material that can be cut into one or more of the card assemblies shown in Figure 1 according to another embodiment
  • Figure 4 is a flowchart of a method for manufacturing an extruded card assembly according to one embodiment.
  • such a thin blocking layer may be formed from two dissimilar materials (e.g., colored pigments and a binder agent) and, when such materials are included in a thin layer, the layer may shrink more than the core layer and thereby cause bending of a card assembly.
  • a thin blocking layer also may suffer from undesirable visual consequences, such as the pigments in the layer forming large, visible gobules.
  • FIG. 2 schematically illustrates a co-extrusion system 200 used to form a sheet of material that can be cut into one or more of the card assemblies 100 according to one embodiment.
  • the co-extrusion system 200 extrudes both the blocking layer 110 and the core layer 104 at the same time (e.g., concurrently) such that the layers 104, 110 are physically bonded together.
  • the co-extrusion system 200 includes a container body 208 holding a supply of material used to form the blocking layer 110 and a container body 210 holding a supply of material used to form the core layer 104. These materials may be in a fluid state in the respective container bodies 208, 210. For example, the materials may be heated in a fluid state in the container bodies 208, 210.
  • the materials can flow, responsive to a pushing force generated by one or more actuators (e.g., rotating screws), out of the container bodies 208, 210 and into corresponding dies 202, 204.
  • the dies 202, 204 have openings shaped to cause the materials flowing out of the container bodies 208, 210 to be formed into the planar bodies or sheets shown in Figure 1.
  • the sheet formed from the co-extrusion of the sheets of the layers 104, 110 may then be cut into one or more card assemblies 100 described above.
  • the resultant sheet formed by the fusion of the layers 104, 110 can have a printable surface 102 (shown in Figure 1) on the layer 110 and a colored core layer 104. Because the layers 104, 110 are physically bonded, fused, or welded together, there may not be a need to laminate the layers 104, 110 together with an adhesive. This can avoid the bending of the card assembly 100, and can reduce the cost and/or complexity of forming the card assembly 100.
  • one or more additional sheets of the layer 110 may be co-extruded with the layers 104, 110 described above.
  • an additional container body and die may be positioned to extrude another layer 110 on the opposite side of the layer 104 so that the layer 104 has two layers 110 extruded on opposite sides of the layer 104.
  • two or more layers 110 may be extruded onto the same side of the layer 104 at the same time that the layer 104 is extruded.
  • Figure 3 schematically illustrates an extrusion system 300 used to form a sheet of material that can be cut into one or more of the card assemblies 100 according to another embodiment.
  • the extrusion system 300 extrudes only one film of the blocking layer 110 or the core layer 104 for bonding with a previously formed film of the other of the core layer 104 or the blocking layer 110.
  • the extrusion system 300 includes a container body 302 holding a supply of material used to form an extruded layer 304 by extruding the material through a die 302, similar to as described above in connection with the co-extrusion system 200.
  • the extruded layer 304 can represent a film of the blocking layer 110 or a film of the core layer 104.
  • a previously formed film 306 may have been created and/or solidified at an earlier time, and may represent the other film of the blocking layer 110 or the core layer 104.
  • the material forced out of the die 302 forms the planar extruded film 304 of the blocking layer 110 or the core layer 104.
  • the extruded film 304 is physically bonded with the pre-formed film 306 by pushing the films 304, 306 together between mechanical rollers 310.
  • the films 304, 306 can be fused together to form a single body (e.g., a film of the card assembly 100).
  • FIG 4 is a flowchart of a method 400 for manufacturing an extruded card assembly according to one embodiment.
  • the method 400 may be performed by one or more embodiments of the systems 200, 300 shown in Figures 2 and 3 to form the card assembly 100 shown in Figure 1.
  • material used to form the blocking layer 110 (shown in Figure 1) is extruded into a planar film.
  • the material may be extruded in a relatively thin dimension, such as no more than two mils thick or another dimension.
  • material used to form the core layer 104 (shown in Figure 1) is extruded into a planar film.
  • the films used to form the blocking layer 110 and the core layer 104 may be co-extruded, such that the films are extruded at the same time or during the same time periods.
  • one or more of the films of the layers 104, 110 may be formed at a different time and/or using a technique other than extrusion.
  • the films of the layers 104, 110 are fused together.
  • the films are extruded and bonded together while the materials of the films are still in a state that is heated and or at least partially fluid.
  • the films can then bond together and cool to form a single body sheet.
  • the films can be bonded together without the use of an adhesive or other material between the films.
  • the fusing of the layers 104, 110 may occur at the same time as the layers 104, 110 are co-extruded.
