A paperback book is a type of book that is bound with a flexible, paper-based cover.
Usually by applying hot melt glue, the backs of the sections are collated and then trimmed before being bound to the cover.
The binding method is the same as the perfect bound, however, instead of hot-melt glue, Polyurethane Reactive (PUR) glue is used.
In this method, the folded sections are collated and sewn together before being glued to the covers’ spine.
The cover and text are bound together using a wire-stitch. This happens along the fold line which is usually in the centre. 2 metal staples are usually used but more can be added.
Round corners can be done by trimming the corners of the pages to form a slightly round edge instead of sharp right angles.
Flaps can be added to the front or back of the book cover. It is usually 1 or 2 folds but more can be added.
