Special Features of the Corrugated Services Linerboard Process

• Fractionation - Long, medium, and short length fibers are separated. Then the fibers best suited for smoothness, printability, and appearance are selected for the top ply. The process results in exceptionally uniform printability and appearance.
  

• Dispersion - stickies and Wax contaminants which might be present in the top ply are
  broken up and dispersed. This final cleaning step insures the cleanest, most uniform sheet possible.
  

• Two fourdriniers - The most proven high performance forming process is used. Each ply of the sheet is separately formed on its own fourdrinier forming section resulting in the best strength and uniformity possible.
  

• High PLI Pressing - The linerboard machine 1^st press is loaded to 1600 pounds per lineal
  inch (PLI) and the 2^nd press to 2400 PLI. The high pressures increase sheet strength through improved fiber bonding.
  

• Hot Press - An additional press is installed in the dryer section especially to create gloss
  and smoothness. This press irons out press marks and molds fibers to an optically smooth
  surface. This results in an extra smooth and glossy sheet which is highly printable and distinctively different from most recycled linerboards produced today.
  

• 3" Cross Direction Moisture Control - The state of the art in cross direction moisture
  control results in sheet moisture uniformity which exceeds the requirements of the most demanding corrugators.
  

• Mill-wide DCS control - Computer linked sensors provide accurate information and consistent, reliable control of the process.
  

• Measurex Paper Machine Supervisory and Control System - Continuous machine and cross direction control of basis weight, moisture, and color.
  

• 24 hour QC coverage - An independent staff of quality control personnel checks paper and roll quality around the clock.
