ABSTRACT:
A hard laminate sheet for security booklets and method of making the same. The laminate sheet comprises at least two hard core layers (e.g. of polycarbonate) and a flexible component (e.g. nylon) there between and extending beyond an outer edge of the core layers to form a flexible band. The flexible component may be provided as an intermediate layer also comprising a hard component (e.g. of polycarbonate) juxtaposed with the flexible component and laminated to the adjacent core layers. The flexible component comprises a plurality of apertures within which material of the adjacent core layers is laminated together and affixes the flexible component to the laminate sheet. Additional hard core layers may be laminated to the core layers which sandwich the intermediate layer. Optionally, the laminate sheet may be used for a travel document (such as a passport) and may be laser engraved. Also, optionally, the laminate sheet may comprise a hard core inlay layer configured for containing a contactless integrated circuit chip and antenna or other electronic hardware.
