ABSTRACT:
A sheet film pack has a pack housing for receiving a plurality of sheet film units in a stack, and a sliding lid for closing an opening of the pack housing, through which a topmost sheet film unit of the stack is moved to an exposure position outside the sheet film pack. The sliding lid has a grip that extends beyond the pack housing in the closed position to close the opening. The sliding lid also has a protuberance that protrudes from an inside surface in the vicinity of the grip. The protuberance is engaged with an edge of the pack housing when the sliding lid is in the closed position, to ensure light-tight contact of the lid with the pack housing even when a large load is applied to the grip.
