A photonic crystal film, a method for manufacturing the photonic crystal film, and an anti-forgery article comprising the photonic crystal film are disclosed. The photonic crystal film includes a polyurethane-based polymer matrix and colloidal particles dispersed in the polyurethane-based polymer matrix and arranged in a crystal lattice structure. The colloidal particles includes one or more selected from metal nanoparticles, metal oxide nanoparticles, organic nanoparticles, and carbon structure nanoparticles.
Two piece transaction card having fabric inlay
Disclosed embodiments generally relate to a transaction card with a fabric inlay. The transaction card may include a housing component having a first housing surface opposite a second housing surface and an inlay component having a first inlay surface opposite a second inlay surface. The inlay and housing may be joined along the second inlay surface and the first housing surface. In addition, the first inlay surface may include a fabric material and a backer layer configured to support the fabric material of the first inlay surface.
Coextruded foil composite material and its use in card bodies
A composite film material usable in a data carrier card body includes a first outer plastic layer, an inner plastic layer and a second outer plastic layer, all the layers together forming a co-extruded composite. The plastic material of the first outer layer is a polyethylene terephthalate glycol copolymer (PETG) or contains a PETG, the plastic material of the inner layer is a thermoplastic copolyester elastomer (TPC) or contains a TPC, and the plastic material of the second outer layer is a PETG or contains a PETG.
Laminating apparatus
A laminating apparatus, in which films can be heated sufficiently, has a simple structure and allows films to be loaded easily. The laminating apparatus includes a sheet feed mechanism unit configured to convey a sheet into an apparatus main body, a film supply unit, and a press-bonding mechanism unit configured to perform a thermal press-bonding process while sandwiching the sheet between a pair of films. A sheet feed unit including the sheet feed mechanism unit is appropriately changeable between an open state and a closed state. The film supply unit includes rollers at supply positions where the films sufficiently wind around heating rollers of the press-bonding mechanism unit. The sheet feed unit includes counter rollers configured to abut the rollers in the closed state and separate from the rollers in the open state.
Patch lamination device and method
A patch lamination device includes a laminate feed roller, a laminating roller, and a laminate spreader. The laminate feed roller is configured to feed a patch laminate ribbon along a laminate path. The laminating roller is configured to laminate individual patch laminates of the ribbon to a surface of a card substrate. The laminate spreader is positioned between the laminate feed roller and the laminating roller. The laminate spreader is configured to reduce the formation of trough wrinkles in a patch laminate that is tensioned between the laminate feed roller and the laminating roller during lamination of the patch laminate to a card substrate using the laminating roller.
Laminating machine
A laminating machine comprises at least one material source, configured as a sheet feeder, for sheets of a material to be laminated. The laminating machine further comprises at least one laminating unit. The laminating machine also comprises at least two lamination sources, each for at least one web-type laminating material. The laminating machine additionally comprises at least one laminating unit for producing a material web, which is laminated on both sides, from the sheets and the respective at least one laminating material. At least one lamination control device is disposed downstream of a laminating region of the laminating unit, along a transportation path provided for the transporting of the laminated material web. The control device monitors a control region, lying outside a transport region that is occupied by the transportation path provided for the laminated material web.
LAMINATE, VERIFICATION, AND METHOD OF PRODUCING LAMINATE
A laminate includes a recording layer, a translucent front covering layer and a security foil laminated between the recording layer and the front covering layer and sealed in the laminate. The security foil has a thickness that is or less the thickness of the recording layer to prevent or reduce falsification reusing the security foil. The security foil includes a relief layer having a relief surface and a protective layer covering the relief surface. In the thickness direction of the laminate, the protective layer adheres to the recording layer and the relief layer adheres to the front covering layer. The adhesion strength between the security foil and the recording layer is higher than the adhesion strength between the security foil and the front covering layer.
Method for Producing a Volume Hologram Film Having Security Elements Formed as Transfer Sections
A method for forming a volume hologram film having security elements which are formed as a transfer section of the volume hologram film is described, wherein the volume hologram film has n volume hologram layers arranged one over another. The production of the volume hologram film is carried out in a roll-to-roll method with the following method steps: a) providing a carrier film from a supply roll; b) applying an i-th photopolymer layer to the carrier film; c) forming an i-th volume hologram in the photopolymer layer; d) forming an i-th volume hologram layer by curing the i-th photopolymer layer; e) repeating process steps b) to e) n1 times; f) applying an adhesive layer to the background layer; g) winding the volume hologram film onto a take-up roll.
