From Warp to Wow: Transforming Corrugated Board Quality with Exilva Bio-based Enhancer

Borregaard | October 20, 2023

In the world of corrugated board production, it's not just about making boxes; it's about delivering quality, savings, and a bottom-line boost. But what's often standing in the way? Warp – the elusive problem that can impact everything from quality to customer satisfaction. It's time for a game-changer, and it comes in the form of Exilva, a natural and bio-based performance enhancer.

Warp in corrugated boards can result in a ripple effect of problems, including waste, customer complaints, and reduced quality. Warp causes increased down time on the converting lines, which is quite costly in productivity and waste.

These production hiccups can take a toll on your bottom line. The cause? Uneven adhesive application, moisture imbalances, and insufficient drying processes.
