Perfect binding is a method of bookbinding that is utilized for many types of less expensive books, manuals, and other simple collections of documents. Unlike some binding processes that require sewing the pages into the spine of the book, perfect binding requires no sewing at all. Instead, a water-resistant adhesive is used to hold the pages in place by attaching them to the cover of the document. The perfect binding book thickness can reach 4cm/ 1.57'', the thickness of dictionary and bibles.
