I think what some may be refering to is that thin box wrapping tape that has 
the strands (filaments) in it, say about 3/4" wide. Most magnetics 
manufacturers use Kapton tape which Mouser and others stock. It has an 
orange-clear color to it, and I think 3M makes it. Not all cores need to be 
taped though. Most ferrite cores for RF circuits just use magnet wire or wire 
with teflon insulation, nothing more. The only reason to use it would be if the 
core is electrically conductive.
