Abstract: A stack of individual sheets of film is enclosed by lightproof plastic packaging. An opaque sheet is disposed at the bottom of the stack, and the side of the opaque sheet confronting the packaging is provided with a bar code containing information about the film. The packaging is removed in a lighttight area of a processing unit for the film and the bar code is read. The opaque sheet prevents the radiation used to read the bar code from reaching the film. The information retrieved from the bar code is employed to control processing of the film.
