The study addresses the challenges of color matching in PCR for rigid packaging, offering options that can create global color consistency, quality, and circularity.
Moreover, coloring processes for dark recycled material can be challenging due to the need for high amounts of colorant to overcome the PCR base color.
Another key discovery from the study: If colorant must be added to the base material to achieve the desired color, the addition of color concentrate can be low (around 2%).
