Why the Packaging Industry Is Moving Toward PFAS-Free CPP Films？
The global packaging industry is rapidly transitioning toward PFAS-free materials. Tightening environmental regulations, brand sustainability commitments, and increasing consumer awareness are accelerating the demand for fluorine-free solutions across flexible packaging.
For CPP film manufacturers, this shift is not only about regulatory compliance—it is a strategic opportunity to improve processing efficiency while strengthening sustainability credentials.
Why Replacing PFAS-Based PPAs Remains a Challenge？
Traditional fluoropolymer-based processing aids have long been used to improve CPP film extrusion. However, removing PFAS from formulations often introduces new processing challenges, including:
♦ High extrusion torque and unstable melt flow
♦ Melt fracture, shark skin, and melt lines
♦ Die drool and die buildup lead to frequent downtime
♦ Surface roughness affects film appearance and printability
These issues can significantly reduce productivity, increase scrap rates, and negatively impact the market value of finished CPP films—especially in high-quality and metallized applications.
Introducing SILIKE SILIMER 9406 – A PFAS-Free PPA for CPP Film Extrusion
SILIKE SILIMER 9406 is a fluorine-free polymer processing additive specifically developed for CPP film extrusion.
Based on a PP carrier and organically modified polysiloxane, SILIMER 9406 migrates efficiently to the processing interface during extrusion.
By combining the initial lubricity of polysiloxane with functional group polarity, it delivers stable, long-lasting processing benefits—without PFAS.
Key Performance Benefits of SILIMER 9406 in CPP Film Extrusion
1. Enhanced Resin Fluidity & Processability
♦ Improves melt flow and extrusion stability
♦ Reduces torque fluctuations
♦ Enables higher throughput with fewer interruptions
2. Elimination of Melt Fracture & Surface Defects
♦ Effectively suppresses melt fracture, shark skin, and melt lines
♦ Ensures smooth, uniform CPP film surfaces
♦ Reduces die drool and die buildup, minimizing downtime
3. Improved Film Surface & Aesthetic Quality
♦ Lowers surface friction for easier handling
♦ Maintains transparency and printability
♦ No precipitation or negative impact on appearance
By integrating non pfas additive SILIMER 9406, manufacturers achieve PFAS-free compliance without sacrificing processing efficiency or film quality.
Real Application Case: SILIKE PFAS-Free Functional Additive for Three-Layer Metallized CPP Film
In a commercial application, a customer applied SILIKE PFAS-free PPA processing aid SILIMER 9406 in the extrusion of three-layer metallized CPP films.
Results observed:
√ Melt fracture, shark skin, and melt lines were effectively eliminated
√ Film surfaces became smoother and more uniform
√ Overall extrusion stability and product consistency improved
This real-world case confirms that PFAS-free PPA masterbatch can match—and even exceed—the performance of traditional fluoropolymer solutions in demanding CPP film applications.
As PFAS-free packaging becomes a global expectation, adopting SILIKE PFAS- and fluorine-free alternative solution SILIMER 9406 allows manufacturers to:
♦ Comply with current and upcoming environmental regulations
♦ Meet brand owners’ and consumers’ sustainability demands
♦ Improve extrusion efficiency and reduce operational costs
♦ Strengthen positioning as a forward-looking, sustainable packaging supplier
If you are producing CPP films and exploring PFAS-free polymer processing aids, SILIKE fluorine-free PPA masterbatch SILIMER 9406 offers a proven, performance-driven solution.
