The Exilva Blog

The last few years have seen a very fast increase in the use of biologicals and biocontrol agents in crop protection and agricultural products as part of the shift towards more sustainable and environmentally friendly agriculture.

With an increasing trend to more environmentally friendly and low VOC paints, waterborne coatings are becoming more favoured over solvent-based coating, due to their lower solvent concentration.

The corrugated business is an industry always in development. After five years of looking into the corrugated industry and how Exilva can be applied to different glue recipes, we have seen elevating results at more than 70 corrugators around the world. Timer after time customer’s state great results. Our latest success story involves a trip to one of the biggest players in the industry. Our common mission was to fix edge delamination that occurs at slitter scorer on double wall and heavy single wall. Names and location of the customer has been anonymized. 

In this blog post 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. Finally, we share feedback and learnings from customers!

To wrap up this corrugated boards application series we finish with a focus on warp. Warp is one of the most common problems that corrugated board manufacturers face. Producing bent or twisted boards results in excessive scrap, waste and reduced production rates. There may be a number of factors that contribute to this problem; leaving out the machinery and focusing on the moisture control in the bonding process, what happens when we add Exilva (Microfibrillar Cellulose, MFC) to the adhesive?

The bonding quality determines the ultimate strength of the corrugated board. In my previous blog post I revealed increased speed results for the production of corrugated boards. In this blog post I have investigated what effect Exilva Microfibrillated Cellulose (MFC) has on bond strength.

Having demonstrated the viscosity stabilizing effect of Exilva in starch adhesives, for this third blog post in the corrugated boards application series, I will focus on the effect on glue ability and production speed.

In a previous blog post, I explained how the new technology of Exilva microfibrillated cellulose may improve the viscosity stability of starch adhesives. Here is the second blog post in the corrugated boards application series, and now I have entered the glue kitchen of a corrugated boards manufacturer to evaluate the robustness and stability effects of Exilva.

Quaternary ammonium compounds (QACs) are a group of cationic antimicrobials widely used for numerous industrial and pharmaceutical purposes. They are disinfectant chemicals commonly used in disinfectant wipes, sprays and household cleaners. They are very popular these days as they allow products to claim to be antibacterial and are part of many EPA listed products with emerging viral pathogens and human coronavirus (Covid-19) claims.
