As well as color correction, this solution also improves the quality and performance of rPET and improves bottle mechanical strength, helping to reduce stoppages, blowouts and scrap while also reducing energy consumption during the bottle blowing process. These factors result in an increased requirement for toners and specialized solutions that are designed to withstand the recycling process, and ensure optimum packaging is achieved in terms of color and quality. THE SOLUTION When added to PET preforms or rPET, ColorMatrix Optica blue toners and color formulations work to correct any yellowing or color variation, resulting in packaging that maintains a neutral or blue color with improved quality and performance.
