We recently introduced an 8 x 8 soft-bound book. Here is some important information about our production process:
Heritage Makers is using a new method of perfect binding called “PUR” which is a hot melt adhesive manufactured with polyurethene reactive material. After the adhesive is applied, a natural chemical reaction occurs as it is exposed to moisture in the air. This reaction creates a superior bond within the fibers of the paper giving the product greater pull and flex strength. It also doesn’t allow the adhesive to get brittle and crack (allowing pages to fall out) like traditional perfect binding components.
We are one of only a few PUR perfect binders in the U.S. and wanting this new technology was one of the reasons we waited to bring soft-bound books on as a product offering.
