2, to have a uniform thickness of cardboard and deformation of the performance, to ensure the normative design of the cover;

3, to have a good stiffness and good mechanical strength, in order to maintain the binding of books, album of practicality and durability;

4, to have a certain layer of strength to meet the needs of the process of binding process;
