The PFAS Ban Red Lines: Fluorine-Free Grease-Resistant Alternatives for Molded Pulp β
The global phase-out of fluorinated chemistry: 12 US states (including California, New York and Washington) and the EU REACH proposal are moving to ban PFAS (per- and polyfluoroalkyl substances) in food-contact packaging outright.
1. The Compliance Red Lines β
| Region | Law / Standard | Testing Threshold | Status |
|---|---|---|---|
| California, USA | AB 1200 / SB 54 | Total organic fluorine (TOF) < 100 ppm; deliberate addition of PFAS strictly prohibited | In force |
| New York State, USA | Environmental Conservation Law | Food packaging containing any intentionally added PFAS is banned in full | In force |
| Parts of Europe | Danish first-mover ban / EU ECHA restriction proposal | Strict limits in paper and paperboard food-contact materials | Strictly enforced |
2. Fluorine-Free Alternatives for Molded Pulp and Food-Service Paperboard β
Conventional grease-resistant paper bags, burger wrap and bagasse food boxes rely heavily on fluorinated grease-proofing agents. Three industrially mature routes deliver fluorine-free grease resistance:
1. Aqueous Acrylic Emulsion Coatings β
- How it works: A water-based polymer forms a dense film over the paper fibers, blocking grease molecules from penetrating.
- Environmental profile: Passes repulpability testing β coated paper goes straight back into the pulper without disrupting waste-paper recycling.
2. Fluorine-Free Greaseproof Agents Added In-Stock (AKD / Modified PVA Blends) β
- Where it is used: Bagasse and bamboo-pulp molded single-use food boxes.
- Performance: Resists hot water (above 85Β°C) and hot oil (Kit rating 6β8), comfortably covering the 30-minute food-delivery use case.
3. Bio-Based Barrier Coatings (PLA / PHA Laminated Paper) β
- Biodegradable with good heat resistance β well suited to high-grease hot and cold drink cups and salad boxes.
