Paper PerFect Formation Analyzer (PPF) - OpTest

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

With the PPF, papermakers are able to rapidly optimize formation in ways unachievable with traditional single index instruments. The PPF quantifies formation into its component values. Individual component values correlate well with paper and board properties such as strength and printability.

The PPF Formation Values are relative to “perfect paper” and to user selected “reference sheets”.

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

 
ADVANTAGES

Quality Improvements
• Print quality
• Sheet strength
• Higher opacity
• Press room performance Production Improvements

Increased machine throughput
• Improved runnability
• Fewer rejects Formation Quality Results

Formation values from 0.4mm to 60mm
"floc” or component size ranges
Excel™ based reports and data files
Displays, stores & prints digital images

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

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