ABSTRACT:
A cassette shell of a photographic film cassette is made of resin. A photographic film is wound on a spool rotatably contained in the cassette shell. A port portion has a passageway for passing the film therethrough toward the outside of the cassette shell. A plush within the passageway for trapping light coming through the passageway is provided in such a manner so as to be removable from the cassette shell when the cassette shell is subjected to a process for reuse thereof. In one embodiment, the port portion is removably attached to the cassette shell. In another embodiment, the light trapping member is adhered to the portion with an adhesive agent soluble in a solvent in which the cassette shell is insoluble.
