ABSTRACT:
A security pocket has a front, transparent panel and a back panel, capable of being printed upon. Three sides of the perimeter of the two panels is permanently bonded, leaving a top opening into the pocket. The back panel includes a closure flap, which carries a permanent, pressure sensitive adhesive and, a tear strip. The front panel includes a removable strip, coextensive with the closure flap, which includes a layer of silicone release material facing the adhesive material. After the pocket is filled, the removable strip is removed and the closure flap is folded over and permanently sealed to the front panel. The transparent panel is a plastic film having significant antistatic properties which enables the flat, empty, two ply pocket to be fed through a sheet fed non-impact printer, without formation of excess static electricity.
