From bottled food and drinks to kitchen table staples, Mesa offers torque analyzers to accommodate the ever-changing needs of the food bottling industry. Pouch and jar caps can be especially challenging in the food industry. New pouch cap TEB designs do not allow release torque to be used as a seal integrity test. Relative application angle, absolute application angle, strip, and other hybrid methods to be used for testing. Jars often have large diameter caps that cause sensitivity to gripping pressure. They are also clamping pressure sensitive and use an induction seal or shrink wrap foil.
Release Torque Testing
Description: With a highly sensitive strain gage-based torque transducer, a 2000 CPR rotary encoder and proprietary pressure controlled cap and bottle gripper designs, our servo-driven automated torque tester can accurately detect both small and large changes in the torque and angle during the removal of a closure.
TEB (Tamper Evident Band)
Description: When tamper evident caps are used just knowing the release torque is not always enough, often knowing the torque required to break the bands is desired. Using a rotation driven release both the thread break and the band break can be measured. (See pg. 45 of ST-120S operator manual for info on how to set this up).
Description: With the ability to deliver and measure up to 88 lbf.in (10 Nm) of torque, we can find and report the torque it takes to strip out the threads when tightening your containers closure.
Description: Used to tighten a cap to a precise torque. Not often used by itself, aside from an evaluation or validation of a capping process, it can also be combined with the release testing for nondestructive testing as well as fatigue and accelerated aging testing.
