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