You know those 2400-foot, 600-foot, and other lengths of half-inch tape
that are used in 7-track and 9-track drives? The reels are commonly
enclosed in plastic straps with latches; the strap with the latch
is the "tape seal". I think "Tape Seal" may actually be a trademark
of Wright Line. The latch part usually has a plastic hook extending
from it that you can hang the tape up by on a Wright Line tape stand
or cabinet.

There are non-Wright-Line tape seals with very different plastic
designs that serve the same general purpose, but are specifically
designed for auto-loading tape drives. These seem to be more
common in IBM shops.
