Product Details

This method is used to measure the force required to separate corrugated board between the flute tips of corrugated medium and its linerboard facings.

Good adhesion of the corrugated medium to its facings is important in obtaining high quality corrugated board and boxes. The pin-adhesion test provides a means of determining the nature and strength of the bond formed during the combining operation and may be used to detect some manufacturing defects, such as poor adhesive penetration, spotty adhesion, and containerboard with low internal bond strength.

The test described in this procedure will measure the Z-direction force required to separate selectively either the inside or outside facing of corrugated board.
