Hi-Op Paperboard PerFect Formation Analyzer

Hi-Op Paperboard PerFect Formation Analyzer (Hi-Op PPF) revolutionizes product quality optimization and productivity by measuring the sheet uniformity at different “scales of formation”!

With the Hi-Op PPF, paperboard makers can optimize formation in ways unachievable with traditional Beta-ray single index instruments. The Hi-Op PPF quantifies formation into its component values. Individual component values correlate well with paperboard properties such as strength.

The Hi-Op PPF Formation Values are relative to “perfect paperboard” and to user selected “reference sheets”.

Samples are easily compared to selected reference sheets such as a competitor’s paperboard or the “best” sheet produced on a particular paperboard machine. The Relative Formation Values are reported for each size component. If this value is one, then the formation of the tested paperboard and reference paperboard are equal. If the value is greater than one, then the tested paperboard is better than the reference paperboard, and vice versa. Relative Formation measurements save time and money when determining the difference between sheets and when optimizing the paperboard machine forming sections.


Formation quality values are reported for each of the 10 components (size ranges) of formation:

Component Range

Process changes affect formation values, at different size ranges. Likewise, different size ranges relate to different sheet properties.
