The production process of softcover books is simple, low in cost, and convenient for mechanized production.The softcover books can be divided into the following types due to the difference of some craftsmanship:1. Wire binding softcover. 2. Sewing and binding softcover. 3. Adhesive softcover. 4. Lock thread and plain packaging.
Adhesive binding is a new binding technology that emerged with the emergence of synthetic glue. Cold glue and hot melt glue are used for glue binding. Lock thread and plain packaging is mostly used for books with higher reading frequency and thicker books. Its characteristic is that the binding thread passes through the crease of the signature, and then all signatures of a book are locked together with thread.
