Paper - Tensile Strength Constant Rate of Elongation

Tensile strength is indicative of the serviceability of many papers including wrapping paper, bags, gummed tape and cable wrapping. The tensile strength of printing papers is indicative of the potential resistance to web breaking during printing and converting operations during travel of the web from the roll through the equipment.

Stretch or bending stiffness is indicative of the paper's ability to conform to a desired contour. This is critical for creped paper, towels, napkins, decorative papers, bags, and liners for cans, barrels or cartons.

Tensile energy absorption is a measurement of the ability of a paper to absorb energy and indicates the durability of the paper when subjected to repeated strains and stresses.

Using a Chatillon^® tensile system, these three tensile breaking properties may be determined.

Industry standards for determining the edge tear resistance of paper is:
