High Performance Paper Coatings with LUDOX®

Reduce Slip and Skid with LUDOX®

Control over the frictional properties of paper and cardboard is very important in the manufacturing of paper based flexible packaging.  Slip and skidding of paper based products due to a low coefficient of friction can be the cause of production delays, increased production cost, and damage to packaged materials.  LUDOX® colloidal silica can be used to effectively increase the coefficient of friction on paper and cardboard to prevent issues caused by slip and skid.

 

Common Issues Caused by Slip & Skid of Paper

Telescopingpaper-storage.png

Telescoping, a defect that occurs during paper winding, can be costly to paper manufacturers and converters using web presses.  Telescoping can occur when a force is applied to a roll of paper that overcomes the coefficient of friction and the edges of the paper become progressively misaligned.  These rolls are difficult to unwind with uniform tension and will deform to cause printing distortions and breakage of the web during converting.

Slipping of Stacked CardboardCardboard-stack.png

Slipping and skidding of stacked paper and cardboard during CNC cutting or boxing can lead to defects in the final product that will ultimately increase production cost.  In addition, slipping of stacked packaged goods during transport and storage can lead to product damage and even result in injury to personnel.

Paper Feed Errorspaper-feed.png

Improper feeding of paper through transport rollers is often caused by inadequate friction between paper and the equipment.  This slipping leads to poor print quality, production delays, and damage to equipment.  In order to combat this problem, frictional properties of the paper to the equipment as well as frictional properties of the paper to paper must be carefully controlled.

 

The Solution: LUDOX®

LUDOX® colloidal silica can easily be applied without prior agitation to liner board paper, photocopier paper, recycled paper, corrugated sheets, and boxes to produce a transparent anti-slip coating on the paper surface.  This coating provides excellent friction retention as well as optimum slide angle performance.  The result is paper rolls that are more resistant to telescoping, corrugated sheets and boxes that are less likely to slip when stacked, and paper sheets that are easier to feed through transport rollers.  In addition, LUDOX® improves ink retention on paper surfaces and enhances print quality on boxes and packaging materials. LUDOX® CL-P and LUDOX® CL-X have been specially formulated to provide optimal anti-slip performance on paper and easy cleanup of coating equipment surfaces.
