Strength enhancer for corrugated medium testliner

Producing paper efficiently and consistently is becoming increasingly challenging. Changing fibre sources, greater use of recycled fibres, and continued pressure on cost and resource efficiency require paper manufacturers to do more with less. Maintaining paper quality, process stability, and reliable performance is more important than ever.

Borregaard's strength enhancers help paper manufacturers meet these challenges by improving strength development and enabling efficient production, helping mills achieve their performance targets while optimising fibre utilisation.

We help you with

Strength

Achieve improved SCT, RCT and CMT even with lower-grade OCC.

Lightweight

Produce lighter basis weights without sacrificing performance.

Sustainability

Enhance your use of recycled fibre with confidence in paper quality.

How our solution borresperse paper improves strength and efficiency

Borresperse® Paper is Borregaard’s range of sustainable, bio-based strength enhancers for recycled corrugated medium. Applied through your film, pond or spray sizer, it works with your existing starch system to solve key industry challenges: increasing strength demands, variable fibre quality and the need for lightweighting.
