A very cool and easy product. Thanks for sharing.
I have had experience with collectible book repairs and a great product for archival binding work is PVA glue. A small bottle is about $10 and will last for 100's of LP repairs. A tiny bead along the detached seam is all you need and won't add more paper material to the inside of the sleeve.
The Seamzeasy would be very good for fully blown out bindings or torn hinges.
Although they do not mention if it is acid free or archival which could discolor an album jacket over time through off-gassing.
