Cloth tying tape is used as a temporay measure to tie damaged volumes and to keep multi-part items together while they await treatment or during transport. It is also used as a minimal stabilization measure for certain low-use materials.
This 3M 415 double-sided tape is pressure-sensitive and, as the name suggests, has adhesive on both sides. The outer surface is protected by a layer of release paper, which is peeled off when the tape is used. It is used only for making enclosures, never affixed directly to a collection item.
This tape is used for making books of sewn-on-tapes construction, to make the ties for portfolio-type enclosures, and to make the lifting tapes of built-up enclosures.
