Beverage caps no longer need look like an after-thought thanks to a new solution from Milliken Chemical that enables caps to copy beverage or brand colour. The system, based on Milliken’s ClearTint colourants technology, is in commercial application in the US and Latin America. Production at three major European drinks companies is imminent.
Milliken trialled its Clear-Tint colourant with a range of PP grades and found the best results with clarified PP – particularly clarified random copolymer grades – that generate high quality transparent colours without the need for re-tooling.
An advantage of ClearTint over conventional pigments is its simplified approval process that, once its five primary colours have been set, does not require approval for every new colour.
