Abstract: A packaging system for 101/2-inch magnetic tape reels in which ten such reels are axially stacked and separated by stacking rings. This axially stacked assembly is then stretch-wrapped in a manner which produces substantial overlap of the stretch-wrap material. A support panel assembly, and two mounting plugs, capture the reels and the wrap material, to thereby seal the reels, and also support the reels with the edges thereof protected. An overpack box conforms to the shape of the support panel assembly, to further support and protect the reels, with the reel edges out of contact with the inner surface of the overpack box.
