COATING STARCH ADVANCES WORLD PULPPAPER78 The papermaking industry and especially the coated graphical papers have to face various challenges. Europe is an aging society in a mature market showing quite limited growth rates. The lifestyles of people are changing rapidly especially with regards to the work environment e.g. home offices and flexibility of people communication and electronic media as well as social networking and on-line shopping to name but a few. For the paper industry these trends led to an increasing consolidation combined with rationalism of companies their production processes and product portfolio. During the crises in 20089 the graphical paper industry was hit heavily and a further decline of about 3 on the average for that year is expected for the future. As a result the paper industry in Europe is now focusing on cost optimisation at maintained quality. The trend towards a greener and more environmentally sustainable paper making process led to an increased use of starches in coating during recent years. Papermakers realised that by using classical coating starches cost optimisation had reached its boundaries. Today some further developments of nature-derived cost effective coating binders remain possible thanks By Dr. Andreas Becker Cargill Technology Manager Industrial Andreas Voigt Cargill Senior Specialist Paper Applications Solutions C iFilm coating starch Customer focused development of nature-derived binder for cost effective coating of Paper and Board The partnership between paper producers and their suppliers is an essential component of product innovation to close cooperation between the papermaker and a starch supplier who is fully aware of their clients specific requirements. PARTNERING THROUGH INNOVATION The partnership between paper producers and their suppliers is an essential component of product innovation. Exchanging ideas and experiences with people from paper production and RD is key as the understanding of customers needs is one of the most important ways to develop the best solution. At Cargill based on our very good experience in paper coating combined with customer knowledge and valuable feedback from our customers we have been able to focus our development on the main product requirements that need to be met maximise coating solids minimise synthetic binder content and improve coating colour rheology all without compromising on paper quality. TECHNICAL OPTIMISATION We know paper coating requires fine-tuning of multiple parameters to optimise runnability and performance e.g. coating colour rheology water retention coater adjustment. It is about taking a holistic view rather than looking at the effect of starch in isolation. Advanced instrumentation techniques allow us to understand the rheological behaviour of starch its interactions with other coating colour components and interactions between the coating colours and the base
