Customer case:

Retention measurement for a stable wet end and optimized paper quality

Jul 19, 2023

Opal Packaging, Australia, is using Valmet Retention Measurement (Valmet RM3) in their BM9 to measure and control headbox and white water consistency, while optimizing their chemical consumption and paper quality. Valmet RM3 improves machine runnability with fewer breaks and higher productivity, and helps with quicker grade changes and startups while running higher machine speeds.

Valmet Retention Measurement at Opal Packaging, Orora Botany

Best instruments are doing their duty in the background without you even realizing. OPAL B9 has been using Valmet RM3 since the start-up at the end of 2012. We are using RM3 to measure and control headbox and white water consistency. The analyzer is very reliable and a low maintenance tool, maintaining wet end stable in our fast-running board machine. RM3 is a great tool for optimizing chemical consumption and paper quality.
