Puncture test of container board
|Publication Date:||1 January 2010|
This tester (Fig. 1) measures the energy required to puncture container board or corrugated board with a pyramidal point affixed to a pendulum arm. Results are reported in "puncture units," comprised of two major components: the energy to tear the material and the energy to bend it out of the way of the point.
