Exilva CostSaver
Reduce adhesive use, lower steam demand, and improve starch system efficiency with Exilva® cellulose fibrils.
Exilva® CostSaver reduces total production costs
In corrugating, high adhesive consumption, steam demand, and inefficient starch systems drive production cost. To maintain stable bonding across varying paper qualities and board grades, you often increase glue load, add energy or use more complex formulations.
Exilva® CostSaver addresses this challenge. It improves adhesive efficiency by controlling penetration and increasing holdout, so more adhesive contributes to bonding. You reduce glue use, lower steam demand and improve starch efficiency. In addition, it allows for simpler and more cost-effective formulations, potentially reducing starch usage and even enabling the substitution of modified starch or one-bag mixes (OBM) with native starch where appropriate.
Borregaard’s technical experts collaborate closely with you to tailor the solution to your specific corrugator and paper combination, helping you achieve consistent performance and maximum cost savings in your operation.
You achieve lower total production cost, better resource efficiency, and stable performance while maintaining board quality.
Bio-based and eco-friendly
100% bio-based and biodegradable1. Derived from natural cellulose, Exilva® supports more sustainable corrugating while improving board stability and converting performance.
Documented performance
Reduces adhesive consumption, lowers steam demand, and supports more efficient use of starch: enabling stable, cost-efficient production across a wide range of conditions.
Compliance
Meets key regulatory requirements, including food contact approvals, and is free from VOCs and hazardous substances.
Technical highlights
- Application: Drop-in, compatible with all starches and corrugating processes – with no CAPEX required and minimal disruption to operations.
- Appearance: White paste.
- Mechanism: Exilva® forms a fibrillar network that stabilizes adhesive behavior and controls water distribution and penetration. This improves moisture balance across the board, reducing warp formation and enabling flatter, more dimensionally stable sheets throughout the process.
- How it works: It controls adhesive penetration into the fluting and liner, materials that often differ significantly in porosity, reducing the amount of glue required.

Commercial benefits supported by trials
LOWER TOTAL COST PER M²
Combined savings in adhesive, energy, and formulation reduce overall production cost.
REDUCED STEAM AND ENERGY USE
Lower adhesive load reduces water input, decreasing steam demand and energy cost.
OPTIMISED STARCH SYSTEM COST
Supports more cost-efficient formulations, including increased use of native starch where applicable.
These improvements deliver measurable value: you reduce adhesive and energy costs, lower the total production cost per m², improve yield through more efficient resource use, and achieve more stable, cost-efficient operations.
Ultimately, improved adhesive efficiency enables you to run corrugators with lower material and energy input, reducing both direct and hidden costs while improving profitability, process stability and overall plant performance.
