Problem Summary

Strength is an important issue in the paper industry and is even more crucial in the recycled fiber market. The quality of recycled fiber is continuously decreasing making it more difficult for paper producers to meet their required specification or match the market trend, which is often decreasing the basic weight.

To overcome this problem, producers have to reduce the paper machine speed, which causes a loss in production, or use starch, sprayed or applied to the Size Press, which increases effluent.

Recommended Solution

Hercobond® Dry Strength Technology is a cost-effective option to recover or reach the strength specification, especially in the recycle fluting and liner markets.

Results show that in many cases, Hercobond® Dry Strength Technology can provide higher strength characteristics, which can overcome the need for sprayed starch or decreasing the applied starch rate in the Size Press, or even decreasing the basic weight.

Key benefits of Hercobond® Dry Strength Technologies include:

Increased dry strength characteristics (tensile strength, burst, concora, short crush test)
Improved quality grade
Decreased basic weight
Increased production rate
Improve drainage and/or reduced steam consumption
Reduced dust in the drying section
Reduced sheet steeling
Reduced breaks
Lower the fiber quality
Reduced effluent load compared to starch
