Moisture proof thermally actuated binding tape for books

摘要

A moisture proof binding tape for edge binding pages to form a book consisting of a non-permeable temperature resistant foil layer covering one side of the backing strip forming a moisture barrier, a high temperature steam resistance adhesive between the foil layer and the backing strip to secure the foil layer to the backing strip, and a relatively thick central stripe of high tack heat activated adhesive flanked by relatively thin side stripes of low tack heat activated adhesive on the foil layer, the central adhesive stripe comprising a non-hygroscopic adhesive.
