What is: Tensile Strength ?

Tensile strength is related to the many stress and strain the paper is subjected to in its end-use applications. Tensile strength is the maximum force required to break a strip of paper of a given width in recommended laboratory conditions. It is also defined as kilograms per 15-millimeter width of the paper strip being tested, or the pounds-per-inch width of the paper strip. The measurement of tensile strength is in both cross-grain and grain directions. However, the tensile strength is greater when the measurement is in the grain direction.
