doesn’t necessarily lead to a dramatic increase in the cost of the formulation either. “When selecting pigments to achieve a set colour


criteria however, we are also mindful that it isn’t just carbon black alone that absorbs infra-red, other pigments can absorb it too. So we will always look for Infra-Red Reflective [IRR] pigments to help provide a wider palette of colour options, but still delivering optimal colour performance to the end product. “At Colour Tone we are therefore always ready to


offer the most creative and innovative new products. Our on-going research and development is the basis for our high quality masterbatches, as we continually look to improve not only their composition, but also our production technology and test methods to deliver market leading results.” The entire life-cycle of the product should be


considered when looking at improving design, and not just in packaging but also other plastic products. This novel NIR technology has the potential to be applied to any number of applications from food trays to auto com- ponents and cosmetic packaging, enabling manufactur- ers to get closer to meeting life cycle analysis goals.


Gaukroger continues: “Using IRR pigments as part of


the colour specification would not present an issue for product designers. For most colours the cost penalty would be minimal, just 0.05 pence [0.06 cents] per food tray for example. It would lend the product an additional marketing advantage too by demonstrating that the supplier is environmentally responsible.” Colour Tone was acquired this year by UK com- pounder Luxus. ❙ www.colourtone-masterbatch.co.uk
