Stiffness Tester (Taber Type)

A physical characteristic of paperboard which differentiates it from paper is its greater flexural rigidity,
commonly called stiffness.

For most of its uses, the economic value of paperboard depends upon its bending resistance (stiffness), and
because this property is closely related to the amount of fiber in the board and hence to its cost, a quantitative measurement is of considerable interest to both producer and user.

Bending resistance (stiffness) of paper relates to a number of end use applications, including wrapping, printing, etc
