Pneumatic Ply Bond Tester

Our Internal Ply Bond Tester is engineered to determine the Internal Bonding Strength of Paper, Paperboard, and Laminates, as per the TAPPI Routine Control Method RC-308. The device measures the average energy required (in thousands of foot-pounds) to delaminate a specimen into two piles, ensuring precise evaluation of bonding strength critical for product quality assurance.

This newly upgraded model offers enhanced accuracy and time efficiency, making it an indispensable tool for laboratories and industries focused on paper and board performance testing.
