Handbooks usually use thin paper (60-80g/m ²) and a hard shell cover structure. The inner pages need to be laid flat at 180 ° without falling off, and the requirements for the flexibility and bonding strength of the adhesive layer are both high. Unlike ordinary books and magazines, hand books have a very high frequency of flipping and are often repeatedly folded. If the glue layer is too hard, the spine of the book is easily broken; If it is too soft, the inner page will fall off.
