Description
A stable, non-flammable film that replaced Cellulose nitrate products. Initially safety film was made from Cellulose acetate, but its introduction to the motion picture industry in 1908 (Eastman Kodak Co.) was unsuccessful. It was soon reintroduced by Pathe Freres in France in 1912 (28 mm size). Kodak introduced 16 mm safety film composed of Cellulose diacetate in 1923 (Cine-Kodak) and 1929 (Lenticular Color). The composition changed to Cellulose triacetate about 1947. Polyester safety film (Cronar) was introduced by DuPont in 1955. Polyester has been the primary safety film since about 1965.
