ABSTRACT:
A film-mount structure comprises a relatively stiff face sheet and a backing sheet which can be peeled off to expose an adhesive for receiving, in a removable and replaceable manner, a film strip for retention and viewing. In order to protect the cellulose-based face sheet from partial separation when the radiographic film is peeled from the adhesive surface, a thin mylar sheet is adhesively attached in a substantially permanent manner to the face sheet, and the releasable adhesive is applied directly to the other side of the mylar sheet. In this way, the film mounts' reusable feature is retained while maintaining the integrity of the face sheet.
