Abstract
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 low tack heat activated adhesive flanked by relatively thin side stripes of high tack heat activated adhesive on the foil layer.
