A photographic cartridge assembly includes a photosensitive film disk rotatably received between opposed parallel walls of a thin cartridge casing. The casing is adapted to be opened, to release the disk for processing and printing, by prying the casing apart until it fractures at one edge and then tearing the casing from the fracture toward the opposite edge. In order to insure that the resulting opening is at a predetermined location in the casing, and is large enough to remove the disk, channels are provided in a casing wall to lead the tear along two paths extending oppositely around the periphery of the disk from the one edge to the opposite edge.
