As global regulations on PFAS-based polymer processing aids (PPAs) tighten, polyethylene (PE) blown film and multilayer film manufacturers face increasing pressure to transition to safer, high-performance, and environmentally compliant alternatives. Forward-thinking companies are already positioning themselves ahead of the curve by adopting PFAS-free solutions early.

To support film producers in maintaining processing efficiency while meeting emerging PFAS restrictions across the EU, the U.S., India’s FSSAI, and other regulatory bodies, SILIKE has introduced the SILIMER Series fluorine free PPA product. This PFAS-free PPA technology features a modified copolysiloxane molecular structure, combining the low surface energy of silicone with polar groups that actively migrate to metal surfaces. Unlike fluoropolymer PPAs, SILIMER Series delivers comparable processing performance without the environmental or health concerns associated with PFAS compounds, helping manufacturers improve sustainability, ensure regulatory readiness, and remain competitive.

What Are PFAS-Free Polymer Processing Aids?
PFAS-free PPAs are next-generation additives designed to enhance melt flow, reduce melt fracture, prevent sharkskin, and minimize die buildup during polymer extrusion—without using PFAS-based chemistries. They provide similar processing benefits while complying with increasingly strict global regulations on fluorinated materials.

Why the Blown Film Industry Is Moving Toward PFAS-Free Alternatives
The industry shift is driven by growing environmental and health concerns, including contamination, bioaccumulation, and potential cancer risks. With regulations such as EU REACH, the US EPA PFAS Action Plan, and state-level bans, manufacturers are accelerating the adoption of safer, sustainable PFAS-free solutions to ensure compliance and maintain high-quality film production.
