    Paperboard bending stiffness tester - technical literature bending stiffness, also known as bending strength, refers to the resistance moment generated when the paper is bent by force within the elastic deformation range, which is a basic physical indicator
    to measure the bending strength of paper.

    Reflected on the carton, the bending stiffness of the paper will affect the bending, compression and torsion resistance of
    the cardboard.

    The thickness, the bulk of the pulp, the degree of beating, the degree of sizing will affect the bending stiffness, but also pay attention to the stiffness and surface hardness is not the stiffness, stiffness and hardness is based on the sound of turning the page to express, tactile hardness and compressibility
    .

    Stiffness is also a must for
    printing paper.

    If the stiffness of the paper is not enough, it will hinder the paper feeding and receiving in the printing process, and the speed of printing will be reduced, and even the performance of printed materials such as books will be poor
    .

    For lithographic paper, a high stiffness of paper is one
    of the basic conditions.

    To detect the bending stiffness of paper and paperboard, it is necessary to use the bending stiffness tester, which is an ideal testing instrument for papermaking, packaging industry, quality inspection agencies and other departments
    .
