Board Laminating Case Study

We work hard to fully understand our customers’ requirements, and regularly create bespoke products should a pre-formulated Pafra adhesive not meet a customer’s specific needs. We recently completed an exciting bespoke piece of work for a large UK based board mill in the laminating sector.

The board mill had a customer looking specifically for a 100% compostable film coated board. The product needed to meet the EN13432 standard for industrial composting. This requirement was a good fit with our expertise as we have long been committed to using the most current and sustainable practices. Our compostable range of adhesives are an environmentally friendly alternative to traditional products and benefit from having high strength bond performance, a high adhesion performance and good machine performance.

Our team took a full and detailed brief to gain an in-depth understanding of the customer’s needs. We sourced a polymer that meets the EN13432 standard and created a new formula that would run on a conventional laminator. Having checked this polymer was capable of bonding the specific substrates, we needed to address the issue of polyurethane dispersion. This instability meant that the adhesive could be difficult to apply due to its fast setting nature. Polyurethanes work well for gravure coating and spraying with high volume, low pressure guns, but as other methods apply a lot of pressure on the dispersion this can cause it to collapse. This can prevent machinery from working and make it difficult to clean.

We had to carry out extensive laboratory work to make it possible to run this material cleanly on a conventional laminator. As the product was designed for Gravure coating, rather than laminating, we believe we are the first company to have created a compostable laminating adhesive for this application. As a result of our work, the customer was able to manufacture a home compostable laminate that meets the EN 13432 and are now manufacturing this product at high volumes.
