There are many options available to paperboard manufacturers to increase the strength of the finished product. Increased refining, starch addition, increased basis weight and addition of dry strength resins are common options. Each of these options has positives and negatives. A new approach to a proven theme is a higher solids liquid dry strength resin technology. This technology and the benefit to paper board manufacturers will be discussed.

As with any commodity, costs of OCC will fluctuate. With the recent down turn in the global economy OCC prices have moderated. OCC now becomes even more attractive as a cost effective and perceived green alternative to unbleached Kraft. However, the more times these materials are recycled the weaker the fiber becomes. This increases the need for strength additives. Traditional dry strength resins have been used for many years without much significant innovation. Most of these materials have significant issues to be addressed before they can be employed. These issues will be reviewed and a new chemistry that addresses most of the issues will be discussed in detail including mill data.
