Optional jigs used with the tensile tester for measuring the internal bonding resistance of paper and paperboard. The specimen with double adhesive tape is sandwiched between two 25mm-square blocks of well-polished stainless steel, and a pressure of 150kgf is applied to stick the specimen to the blocks. As in the tensile test, the lower clamp is moved downward to apply a delamination load to the paper layers. Then the blocks are fixed in the clamps of the tensile tester. Tension is applied as in the tensile test to delaminate the specimen. The load at the rupture of paper layers is recorded. In addition, the position of delaminated layers is determined and the state of delaminated surface is observed.

The bonding strength of adhesive paper and adhesive paper tape is usually measure by the 180° constant-speed peeling test. These jigs are mounted on the upper frame and moving crosshead of the constant-speed tensioning universal tester. The specimen is secured by the upper and lower clamps, through two low friction guide rolls, and loaded as in the ordinary tensile test. A special mechanism is provided so that the peeling point is always located in the vertical line passing the upper and lower clamps, to achieve high accuracy and reproducibility. By changing the position of the rolls, you can use this instrument for a wide range of thickness and hardness of specimens.
