| Aqueous coating | Water and grease |
| PLA film | Water, grease, heat seal |
| Wax blend | Water, low cost |
| PFAS-free barrier | Grease, food-safe |
FAQ
Q1: What coatings are used on molded pulp?
A: Aqueous coatings, PLA films, wax blends, and PFAS-free grease barriers are the main options.
Q2: Which coating stays recyclable?
A: Aqueous and PLA coatings keep trays recyclable or compostable; heavy wax complicates recovery.
Q3: Is there a food-safe grease barrier?
A: Yes — PFAS-free grease barriers meet food-contact rules for bakery and takeout.
