CLEVELAND – July 8, 2019 – PolyOne today launched a new portfolio of infrared- detectable black colorants for plastic packaging, which will allow formerly unrecyclable black waste plastic to be properly sorted at recycling facilities. PolyOne’s new black colorants address this issue by eliminating carbon black and enabling black plastics to be sensed, sorted, and recycled efficiently. PolyOne employs approximately 6,900 associates, is certified ACC Responsible Care® and Great Place to Work®, and is a founding member of the Alliance to End Plastic Waste. 

Plastic / metal hybrid designs can bring the best of both worlds – reduced weight and structural integrity. Investigate processes that enable plastics and metal to be formed together, including insert molding and heat staking. Take advantage of hybrid plastic/metal designs

The global preference for plastics in consumer packaging has led to explosive growth and the production of hundreds of millions of containers for different applications per year. Along with the tremendous benefits that plastics bring to society, there is also a responsibility to ensure plastic waste does not end up in the environment. Ultimate is recognized by the Association of Plastic Recyclers and the European PET Bottle Platform for having no negative impact on the recycling stream.

Cesa™ Slip lubricants improve the flow characteristics of plastics during processing. Improves the flow characteristics of plastics during processing A full line of dispersions for rubber and plastic applications.

With the recognition, OnColor™ NIR Sortable Colorants are preferred for high-density polyethylene (HDPE) resin in black and dark colors, according to the APR Design® Guide for Plastics Recyclability. OnColor NIR Sortable Colorants from Avient provide a solution to this problem, allowing the packaging to be visible to a NIR optical sorter, enabling it to sort into the correct plastic stream. Avient is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.
