Security films that are useful for pharmaceutical packaging. In particular, anti-counterfeiting security films having a luminescent composition on or in a fluoropolymer layer, which luminescent composition luminesces upon the application of ultraviolet radiation in the 200 nm to 300 nm range, in which the luminescent component is optionally and preferably not viewable to the unaided eye. The films are particularly useful for the formation of anti-counterfeiting blister packaging in compliance with FDA regulations.
