Chroma Color® has developed a specialized formulation path to solving the need for colorant alternatives to Carbon Black as a means to address the recycling of black or dark colors in packaging for improved environmental sustainability.

Chroma Color®’s alternative recipes allow the MRF sorting operations to identify and successfully sort the plastic articles according to the APR NIR Sorting Potential of a Whole Plastic Article. The leading third-party independent lab P.T.I. of Holland, Ohio, conducted all testing and analysis.

ChromaNIR’s Sortable Black Technology is based upon IR reflecting/transparent components using a proprietary combination of specialty dyes and organic pigments. The Chroma Color® path to success allows for expanded exploration of additional Black options, including near-Black and other Dark Color families.

ChromaNIR’s TESTING BASICS:

-The following packages were evaluated using the APR test method: Near Infrared (NIR) Sorting Potential of a Whole Plastic Article (Sort-B-01).

– A total of five recipes were tested using bottles made by extrusion blow molding.

– Three carbon black free formulations were tested in HDPE and One in PP.

– One control formula with carbon black was included.

ChromaNIR’s RESULTS:

– Four Carbon Black Free recipes passed with 100% sortation.

– As anticipated, the one control formula with carbon black failed with 0% sortation.

– A leading independent lab PTI of Holland, OH, tested the plastic articles.
