Certification Bodies Favor Process-Based Grease Resistance
Major compostability certification bodies have begun favoring process-based grease resistance achieved through fiber supercalendering over applied plastic or wax coatings, since coated papers require separate coating-level disintegration testing that supercalendered papers pass without any additional verification step. This is pulling food-service operators that previously accepted coated grease barriers as the default into direct supercalendered paper specification choices, since certification now depends on grease-resistance method rather than grease-resistance outcome alone. Operators that completed this conversion are citing simplified certification pathways directly in sustainability reporting, pushing additional categories toward similar supercalendered commitments nationwide.
