CORRUGATED BOARD GLUES
Improve board quality, production efficiency and process stability with Exilva®
stronger board, lower cost, faster run
What if your corrugator isn’t the constraint, your glue system is?
Corrugators are under constant pressure to increase throughput, reduce total cost, and deliver consistent board quality across more demanding substrates. Yet many plants still operate below true capacity. One of the factors that can limit performance is the adhesive system. Instead of fully supporting the process, it can introduce variability, influence achievable speeds, and impact both waste levels and downstream conversion efficiency.
Rethinking your adhesive system
Exilva® is Borregaard’s bio-based performance technology for adhesive systems, developed to tackle these challenges directly. Added in the glue kitchen, it enhances how your adhesive performs—improving stability, strengthening bonding, and enabling more efficient production. The result is lower glue consumption, reduced energy use, and flatter, stronger board with less waste.
Combined with our technical service, Exilva becomes part of a complete performance solution. Our specialists optimise your adhesive system to your corrugator, optimize process parameters and machine settings, and ensure performance under production conditions. This helps ensure stable day-to-day production performance, not just in theory, but on your corrugator.

Read moreProven performance
Small improvements in glue performance have a direct impact on overall corrugator efficiency. More stable adhesives mean fewer interruptions, more consistent bonding, and the ability to run at higher speeds without increasing risk. At the same time, reducing glue and steam usage lowers both raw material costs and energy consumption—without compromising board quality.
These advantages translate directly into measurable results: customers have reported up to 47% reduced glue consumption, 12% lower steam usage, and up to 63% higher production speed, along with improved bonding.

From nature to know-how
Everything you need to know about cellulose fibrils in corrugated board
In this article we have collected our key learnings from working with corrugated board in over 170 trials. You will find information about reduced starch consumption, prolonged stability of viscosity in starch adhesives, robustness, increased productivity, bonding quality and how to fight warp.
Fighting warp from the inside - flattening effect with exilva
In this article we focus on warp. Warp is one of the most common problems that corrugated board manufacturers face.
The secret to stronger corrugated boards
In this article I have investigated what effect Exilva Microfibrillated Cellulose (MFC) has on bond strength.
Customer results
Over a two‑year collaboration, Norwegian corrugated board producer Glomma Papp and Borregaard have tested and developed a boron‑free corrugated board solution using Exilva Combo. The work addresses increasing regulatory concerns around boron derivatives while demonstrating how Exilva can enhance board quality and productivity in industrial production.
Based on approximately 70 million m² of boards produced with Exilva, Glomma Papp measured a 14% improvement in productivity and an 11% reduction in warp.
Frequently asked questions
-
How is Exilva implemented in an existing corrugator setup?
Exilva is added directly in the glue kitchen and can be integrated into existing adhesive formulations without major equipment modifications. Our technical specialists support the implementation by optimising glue recipes and process parameters.
To evaluate the impact in your own production, you can request a trial with our team and measure the results directly on your corrugator.
-
How does Exilva reduce glue consumption in corrugated production?
Exilva improves the efficiency of starch-based adhesives by enhancing their stability and bonding performance. A more consistent adhesive system reduces the need to overdose glue to compensate for variability, allowing for lower starch usage while maintaining performance. In practice, this enables measurable reductions in glue consumption without compromising board quality.
-
How does Exilva improve bonding and prevent delamination?
Exilva strengthens the adhesive bond by improving fibre interaction and ensuring a more uniform distribution of the adhesive across the paper surfaces. This results in stronger, more consistent bonding, even across varying paper grades and operating conditions. By reducing weak points in the bond, the risk of delamination during production and downstream use is significantly lowered.
-
Can Exilva replace boron in corrugated adhesive systems?
Exilva contains no added boron and is a bio‑based alternative that can partly or fully replace boron derivatives in starch‑based corrugating adhesives, while maintaining bonding performance and process stability.
To explore how this can work in your setup, you can contact our team to discuss your requirements and request a trial.
-
How does Exilva improve bonding performance?
Exilva improves bonding by stabilizing the adhesive and ensuring a more uniform and well-controlled glue film on the flute tips. This leads to stronger, more consistent bonds and better interaction between paper layers.
In industrial trials and customer cases, this has resulted in improved bonding strength, reduced delamination, flatter boards, and fewer bonding-related defects.
-
How does Exilva reduce glue and energy consumption?
By stabilising the adhesive system and improving bonding efficiency, Exilva enables lower glue usage and reduces the need for excess steam. This translates directly into lower raw material and energy costs on every run.
In multi-week trials and production cases, this has resulted in up to 47% reduction in glue usage and up to 12% lower steam consumption. -
How does Exilva help reduce waste and rejects?
More stable and predictable adhesive performance leads to consistent board quality. This reduces production variability, minimises defects, and allows operators to run faster without compromising quality.
In industrial trials, this has led to fewer bonding defects, less warp, and consequently a reduction in waste and rejects. -
How does Exilva enable higher operating speeds?
Exilva improves adhesive stability and bonding reliability, allowing corrugators to increase speed without increasing process risk. This helps unlock unused machine capacity while maintaining consistent performance.
Across multiple trials and case studies, this has enabled up to 67% increases in operating speed, depending on grade and setup.
