What glue is used for book binding?

Nowadays, eva-type hot-melt adhesives are generally used to stick the sides of books, and pur-type hot-melt adhesives are also used, but the cost of using pur hot-melt adhesives will be slightly higher.

The process of gluing the spine of the book is as follows:

After folding the pages, smash the pages on the spine of a certain depth to facilitate the penetration of the glue, and then apply glue to press down. After this process is completed, wait for the glue to dry on the back of the book, and the binding step of the book is complete.

However, if the pages of the book are difficult to stick, and it is easy to peel off the pages by directly milling and gluing on the back, it is necessary to lock the thread before gluing, and then gluing, so as to improve the firmness of the spine. In addition, thick books also need to be locked first.

After seeing it, someone asked: Can a book that has been perfect-bound be re-bindered? – Theoretically it is possible! But trouble, consider whether the depth of the reserved gluing spine is not enough, and the back of the book to be re-glued must also be flattened.
