Final answer:
The sensitive emulsion is not found on the label side of a film packet; it is coated on the film base within the packet and is exposed to x-rays to capture dental structures, only becoming visible after processing.
Step-by-step explanation:
The label side of a film packet in dental radiography typically includes several pieces of information which are essential for identifying and organizing the radiographs. It would feature the patient's name or identification number, the type of film, the exposure time, and sometimes the date of the radiograph. What you would not find on the label side of the film packet is sensitive emulsion, as this is actually part of the film itself, placed within the packet and is sensitive to x-rays. The emulsion is coated on both sides of the film base and is protected by the outer cover of the packet. The purpose of the emulsion is to record the dental structures, which become visible after the film is processed.
