Abstract
A dental radiographic film packet includes soft corners for greater patient comfort. Corner areas contain additional air space to permit additional flexing of the film chip in these areas. Furthermore, other internal structures, such as cardboard elements, have been removed to increase flexibility in these areas. The outer surface of the film packet is seamless at the corners to eliminate any sharp edges.
