Intended for the home, Ozaphan was a nonflammable film derived from cellophane. Instead of an emulsion coated base, Ozaphan incorporated a light sensitive dye into the base itself. The film was half the thickness of celluloid film, making it cheaper and able to fit on smaller reels. It was used only in the projector; the negative was shot on conventional film.

The most common subjects were non-fiction and animation. The 1936 Olympics in Germany was well-documented. In the years immediately before the Second World War, political films became more common. Production ended in 1941. Ozaphan made a comeback in the 1950s and 1960s, including an 8 mm version, but Ozaphan film was inherently black and white and could not ultimately compete with conventional film. By the late 1960s production ceased for good.
