For my money, there ought to be one always, though careful handling in a
controlled environment can probably get away with skipping them.
Shipping is where the worst stresses occur, of course, so is the most
important.  I've received a number of tapes for imaging over the last
few years, and I don't think a single one had anything to keep it
packed.  One such tape had slipped an outer chunk of the pack around the
inner rest, producing a hard crease.  Needless to say, there was a read
error there.
