The Polaroid 405 back for 4x5 takes packfilm; main caveat is that you need a graflock in order to use it without modifying the camera.
Else-wise, look for a Mamiya Press or Universal, which has an interchangeable Polaroid back as part of the system; the Polaroid 600SE is similar with a more limited range of lenses.
