Background: Tightening PFAS Regulations in the EU and US
Growing environmental concerns and scientific findings on the health risks of PFAS (per- and polyfluoroalkyl substances) have prompted global regulatory bodies to act. The European Chemicals Agency (ECHA) is advancing proposals for a comprehensive PFAS ban, while the U.S. Environmental Protection Agency (EPA) is enforcing stricter limits on PFAS content in food-contact materials and wastewater discharge.
These developments are reshaping the packaging industry, creating a pressing need for PFAS-free paper treatment solutions—particularly in grease-resistant food and industrial packaging applications.
Technical Pathways: Types of Fluorine-Free Oil Repellents
Fluorine-free oil repellents achieve barrier performance without relying on fluorinated compounds. Instead, they utilize alternative chemical mechanisms to reduce surface energy and increase oil contact angle. Common types include:
- Wax-Based Oil Repellents
Create a physical barrier on the paper surface; ideal for moderate grease resistance in dry food packaging. - Silicone-Based Oil Repellents
Form a flexible and hydrophobic film with good thermal stability; suitable for high-temperature applications. - Polymer-Based Oil Repellents
Rely on waterborne synthetic polymers to modify paper surface chemistry; provide balanced oil resistance and printability.

Performance Comparison: Fluorinated vs. Non-Fluorinated Repellents
| Criteria | Fluorinated Repellents | Fluorine-Free Repellents |
|---|---|---|
| Oil Resistance | Excellent (KIT ≥ 10) | Good (KIT 6–8, enhanced with formulation) |
| Water Resistance | Excellent | Good to Moderate |
| Food Safety Compliance | Risk of PFAS migration | PFAS-free, FDA/EU compliant |
| Sustainability | Poor (non-biodegradable) | Renewable, biodegradable options |
| Regulatory Acceptance | Banned/restricted in EU/US | Meets global green packaging standards |
Application Scenarios
- Food Wrappers & Liners
Ideal for contact with dry or moist food items—enables clean, oil-free surfaces. - Greaseproof Industrial Wrapping
Suitable for automotive or machinery spare part packaging where oil seepage needs to be contained. - PFAS-Free E-commerce Packaging
Used for paper bags and mailers that demand both sustainability and resistance to grease or staining.
