A light-proof tearable sheathing for a pack of photographic or X-ray sheet films insertable in a film supply magazine of a film cassette-loading device includes a winding flap which is wound on a shaft of the winding device to pull the sheathing from the film pack, a folded connection flap opposite to the winding flap and glued to the sheathing by a glue tape, and a tearing tape provided between two spaced strips of the glue tape and tearable from the sheathing to open the latter for the removal therefrom of individual film sheets.
