A method of making a printed identification card core (51), a printable sheet (31) for manufacturing cores (51) for laminated identification cards (61) and a core (51) for a laminated identification card (61). The method includes the steps of extruding polyethylene (13) onto one side (15) of a release film (17), laminating a porous, printable polyolefin film (19) to the polyethylene side of the release film (17), die cutting the polyolefin film (19) and the polyethylene film (13) to form rectangular bodies (41) each having a die cut transversely extending fold line (47) dividing each of the rectangular bodies (41) into two identically sized rectangular panels (43, 45), printing on the porous, printable polyolefin film (19) within said panels (43, 45), removing a rectangular panel (41) from the release sheet (31) and folding the rectangular body (41) about the fold line (47) to locate the printed polyolefin surfaces on the exterior of the core (51). The core so manufactured can be inserted into a laminatable pouch (53) and laminated to the core (51) to form a tamper resistant identification card (61). The printable sheet (31) includes a plastic sheet (17) having a release surface on one side (15) thereof, a layer (13) of extruded polyethylene applied to the release surface of the plastic sheet (17), a layer (19) of porous, printable polyolefin applied to the layer (13) of extruded polyethylene and die cut panels (43, 45) formed in the layer (13) of extruded polyethylene and the layer (19) of porous, printable polyolefin. The core (51) for the identification card (61) includes an inner layer (13) of polyethylene on each side of the core, a pair of layers (19) of porous, printable polyolefin located outwardly of the inner layers (13) of polyethylene and printed indicia (48, 50) on the outer faces of the layers (19) of printable polyolefin. |
