October 2024 Düsseldorf, Germany Maritim Airport Hotel ONLINE, Live-Stream World Congress Platinum Sponsor KOREA PACKAGING ASSOCIATION INC. Media Partner Premium Media Partner Supporter Diamond Sponsor www.pef-world-congress.com Solutions for sustainability and PCR content in packaging Avient Corporation showcased solutions to enhance the customer experience when working with post-consumer recycled (PCR) content, particularly in packaging applications. Among the highlighted technologies were advancements specifically beneficial for PET bottle applications, as Dr Jan Sültemeyer, Global Sustainability Leader at Avient, revealed. One of the key technologies introduced was the Colormatrix AAnchor Acetaldehyde Control Technology. This newly formulated acetaldehyde (AA) scavenger has been specifically developed for PET packaging to address the challenges associated with increased rPET content. AAnchor not only aims to improve the recyclability and quality of PET packaging but also to reduce risks related to regulatory compliance and the migration of the active AA scavenging component and non-intentionally added substance (NIAS) species, which are often concerns with other types of AA scavengers. Dr Sültemeyer elaborated on the rigorous testing the scavenger underwent: “We have thoroughly tested AAnchor in our Global Technology Center in Knowsley, UK. Our CycleWorks Innovation Center is also able to simulate complete material performance chains in mechanical recycling on a scale of 50-100 kg, enabling us to test for issues such as deposits in the mould, which are common with other products.” He further emphasised that even at temperatures exceeding 300 °C, the stability of the scavenger was maintained. AAnchor has been adopted by a customer in the water sector and was recognised as a finalist in the Product Technology Innovation of the Year category at the PRSE Awards. Another solution showcased was laser marking for label-less or naked bottles. “This method offers significant advantages by eliminating the need for printing inks, thus removing the necessity for de-inking during the recycling process,” explained Dr Sültemeyer. “Laser marking is a growing trend, and our additives can increase the marking speed and enhance contrast for better readability”. www.avient.com F.l.t.r.: Jan Sϋltemeyer, Global Innovation and Sustainability Manager, Mirco Groeseling, Market Development, Packaging and Sustainability Manager, John McClelland, Sales Director, Avient
