Former Useful Method 808 "Plybond Peeling Strength of Linerboard and Corrugated Board" described a simple method which indicated the peeling strength of the weakest ply in a multiply sheet. This procedure can also be applied to the liner after corrugating. A new working group has been formed to reinstate and revise this procedure, with the goal of bringing the method into compliance with current UM guidelines.
If you would like to join the working group and participate in the reinstatement of this Useful Method, please send a message to standards@tappi.org no later than December 7, 2012.
