Case Study: a global bottling company achieves consistent plastic cap and preform color with HunterLab

Global Bottling Company standardizes plastic cap and preform color across plants with HunterLab

HunterLab worked with a global bottling company that was facing challenges with color consistency in its plastic caps and PET preforms across multiple production plants. The customer was using a mix of different color measurement tools, including the ColorFlex EZ for caps and the Vista for beverage color, which led to inconsistent data. This variation was a significant risk to brand integrity, especially as the effects of functional additives like oxygen scavengers on color were not well understood.

HunterLab implemented a solution featuring custom-designed accessories, including cap port plates for the ColorFlex EZ and large preform holders for the Vista, to ensure stable and repeatable measurements. They supplemented this with hands-on color training for the customer's teams. As a result, the global bottling company achieved consistent color measurement across all plants, streamlined its workflows to reduce operator error, and gained greater confidence in tracking additive impacts and making quality decisions.
