With the startup of Green Bay Packaging’s new paper machine just weeks away, the Kalamazoo, MI division purchased a Chalmers DST to enhance their testing lab and compliment their design capabilities.
This will make 8 (eight) Chalmers DST for the group as they make light-weighting and right-weighting a priority.
The Chalmers DST measures the structural quality of combined board produced at the corrugator and measures the damage (crush) that occurs during the converting process. This quality can be compared to what should be obtained on undamaged board and a Performance Indicator calculated.
The DST is much more sensitive than caliper, ECT, and BCT and provides feedback in twelve seconds so real time on machine adjustments can be implemented.
Based on the calculated Performance Indicator, the DST can give a very good idea of what the likely stacking performance will be and also the effects of cyclical humidity creep. It is the only test that provides an accurate indication of how a box will perform in a real world environment.
About Korutest Ltd
Korutest was incorporated in 2007 to commercialize the Chalmers DST corrugated board torsional stiffness tester developed at the New Zealand Forest Research Institute in 2004. Uptake of the DST in Europe by companies like DS Smith, Saica, StoraEnso and many smaller companies has been gratifying. In the USA DS Smith, Georgia Pacific, Green Bay Packaging and many other companies are taking advantage of the DSTs usefulness to lower packaging paper weights and improve performance at the same time.
