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. Brand owners and packaging manufacturers who need to use increased levels of rPET content, in support of their sustainability goals and the circular economy, should benefit from this solution.
