Natural performance booster for Corrugated Board Glues
Exilva is Borregaard’s innovative bio-based performance backbone for corrugated board glues. It strengthens bonds, improves glue stability and enables faster production – helping you reduce glue and energy consumption while producing flatter, stronger board with less waste.
Why it matters
In modern corrugating operations, producers must continuously optimize glue performance, reduce waste, and increase speed – whether dealing with demanding substrates like coated paper, heavy kraft, ultra-light liners, and SC fluting, or standard recycled and lower-grade papers. Exilva is added directly in the glue kitchen, delivering technical advantages that translate into clear commercial value.
Key benefits:
- Improve bond quality and strength: Achieve stronger ECT and consistent bonding across all paper grades.
- Run faster and reduce waste: Higher bond strength means higher corrugator speeds, less warp, fewer delaminations and flatter board.
- Lower glue and energy costs: Use less adhesive and reduce steam consumption thanks to faster bonding and drying.
- Better glue stability: Controls viscosity drift and penetration for consistent glue performance.
- Supports sustainability goals: Fully bio-based and enables boron-free operation; safer in use than synthetic alternatives.
- Versatile and easy to integrate: Works with all board qualities, processes and recipes — from kitchen prep to final box.

Customised optimisation
Every corrugator is different. Borregaard’s technical team partners with you to run tailored Exilva trials, demonstrating clear performance gains for your specific process and benchmarks.
