ABSTRACT:
A semi-laminated security pouch for a tamper proof identification card is disclosed. The identification card to be protected by the security pouch has a glass bead security coating on a front face which provides an indication if indicia are tampered with on the face of the card. The pouch comprises front and rear film leaves with a heat reactivatable adhesive layer on the rear leaf card-facing surface. The rear surface of the card is centered against the rear leaf for lamination. The front leaf does not have a heat reactivatable adhesive layer thereon since such a layer would destroy the retroreflective visual characteristics of the glass bead security coating. The front leaf card-facing surface does, however, have the bond promoting coating thereon such that when the pouch is assembled, peripheral portions of the front leaf come in contact with peripheral portions of the rear leaf extending beyond the card edges. The bond promoting coating permits adhesion between the polyester material front leaf and the heat reactivatable adhesive at peripheral portions of the rear leaf.
