ABSTRACT:
A package comprising a light-proof envelope or bag containing a plurality of X-ray film sheets stacked for co-operation with a dispensing machine and useful in a daylight handling system for daylight loading and unloading of cassettes. The film sheets are identical and may have a photographic emulsion layer on one or both surfaces. The adjacent films in the stack have their surfaces in contact. Each sheet has a cut-away portion along one edge thereof for coacting with a film selector cam. In the stack, the sheets are alternated so that the cut-away portions lie along a common stack edge and are arranged in two parallel rows. The cut-away portions in adjacent sheets are in different rows and in superposition. After the package is in a dispenser, the envelope or bag is stripped from the stack so that the sheets can be removed one at a time from the stack and passed into film holders or cassettes engaged with the dispensing machine.
