Introduction:
Polymer processing aids (PPAs) are indispensable in optimizing the performance of polyolefin films and extrusion processes, particularly in blown film applications. They serve crucial functions such as eliminating melt fractures, improving film quality, enhancing machine throughput, and minimizing die-lip build-up. Traditionally, PPAs have heavily relied on fluoropolymer chemistry for their efficacy.
However, the utilization of fluoropolymers has faced scrutiny due to their categorization as PFAS materials (per or poly- fluoroalkyl substances). Recent regulatory actions, such as the proposed total ban on PFAS and fluoropolymers in the latest REACH dossier of February 2023, have intensified the pressure on brand owners to seek alternatives devoid of PFAS. This has led to a concerted effort among polyethylene resin producers and film converters to explore PFAS-free options for flexible packaging applications in response to market and legislative demands.
The Emergence of PFAS-Free Polymer Processing Aids (PPA) Solutions:
In the pursuit of sustainable manufacturing practices, the shift towards PFAS-free polymer processing aids is both imperative and inevitable. By embracing these alternatives, industries can uphold their commitment to environmental responsibility, protect human health, and meet the evolving demands of consumers and regulatory authorities. It’s time to bid farewell to PFAS and embrace a future of cleaner, safer, and more sustainable polymer processing.
Enter the era of PFAS-Free Polymer Processing Aids (PPA)
These groundbreaking alternatives offer a compelling solution: the ability to achieve superior film quality without compromising on environmental integrity. Companies like Ampacet and Techmer PM have joined the movement by introducing PFAS-free polymer processing aids, showcasing performance on par with fluoro-based PPAs in blown film extrusion across various end-use applications However, SILIKE emerges as an innovative force in this evolution, its SILIMER PFAS-free polymer processing aids offer comparable or even superior performance to traditional fluoro-based PPA’s, all while eliminating the risks associated with PFAS.
