Scott Plybond

The Scott Plybond test measures the internal bonding strength of paper, using a lifting motion that is somewhat similar to peeling. A pendulum strikes an aluminum angle bar that has been taped to the paper. If the paper has high internal bond strength, the energy in the pendulum is absorbed to a greater degree. This test is used for both single-ply products and multi-ply products, and is run according to TAPPI Test Method T569.
