ABSTRACT:
A microfiche film pack having a pair of opaque covers, one of which is formed with an offset portion providing a pocket. A sheet of photosensitive material is partially positioned in said pocket, and has a tab which extends from the pocket, there being a light trap in the form of elongated indentations in said covers on opposite sides of said photosensitive sheet. The tab near the indentations is formed with several apertures through which the covers are bonded to each other to cooperate with the indentations in providing the light trap.
The covers are provided with an end portion to be held in fixed position relative to the tab on the photosensitive sheet to enable the latter to be pulled from the pocket in the covers.
