Pin Adhesion Testing

The pin adhesion test measures the bond between the liners and the corrugated medium in a corrugated paperboard structure. It is tested by measuring the force required to separate the facings from the flute tips. The test is conducted using a special fixture in combination with a crush tester such as that used in the testing described above.
