This nonflammable mildew proof material is easy to dye and is available in many colors. Cellulose acetate film or safety film is used in photography as a base material for photographic emulsions.

Cellulose acetate became widely used in the automotive industry because of its mechanical strength toughness wear resistance transparency and ease of moldability. The cellulose acetate membranes have improved solvent resistance particularly to low molecular weight alcohols and increased heat resistance. Cellulose acetate is used as a film base in photography as a component in some coatings and as a frame material for eyeglasses. Cigarette filters are usually made from cellulose acetate fibre but sometimes also from paper or activated charcoal either as a cavity filter or embedded into the cellulose acetate.

It is also used as a synthetic fiber and in the manufacture of cigarette filters found in screwdriver handles ink pen reservoirs and x ray films. In photographic film cellulose acetate replaced nitrate film in the 1950s being far less flammable and cheaper to produce. A nitrocellulose slide nitrocellulose membrane or nitrocellulose paper is a sticky membrane used for immobilizing nucleic acids in southern blots and northern blots.
