Waterbased barrier coatings for sustainable packaging innovation In close collaboration with paper and board producers, food packaging convertors, retailers and major brand owners, TopChim develops water-based barrier coating solutions for the manufacturing of environmentally-friendly fibre-based packaging systems that require specific barrier performances. Increasing demand for easily recyclable and biodegradable packaging is driving the innovation team of TopChim to provide an alternative to replace paraffin coatings and the use eco-unfriendly fluorinated compounds to increase the sustainability of food packaging and easily applicable coatings for mono-layer packaging systems to substitute hard-to-recycle multi-material packaging using polyethylene. TopChim NV/SA was established in June 1996. We are a Belgium based and world-wide operating research driven chemical company, specializing in coating technology. We apply the latest technologies in chemical science to develop high-performance ecological coating solutions for the paper, cardboard and packaging converting industry. The pioneering work in chemistry and biopolymer technology is the result of active collaboration with European institutes and universities involved in our fundamental research. The research efforts of our science department have been translated amongst other things into the production of waterborne dispersions of biopolymer pigments on an industrial scale. TopChim is committed to continuing its search for solutions for optimal paper and board coating production that are both environmentally friendly and economically attractive. We are focused on the success we can bring to our customers' operations through innovation.
