Grease-Proof Paper Coating
report_problem Problem Statement
Food-contact paper packaging — including burger wrappers, pizza boxes, microwave popcorn bags, and bakery bags — relies on PFAS-based grease barriers to prevent oil strike-through. PFAS are persistent 'forever chemicals' detectable in the blood of 98% of Americans. Studies show PFAS migrates directly from food packaging into food, with fluorotelomer compounds in fast food wrappers linked to elevated PFAS blood serum levels in regular consumers.

gavel Regulatory Drivers
EU regulation banning PFAS in food contact materials (effective August 2026). Denmark banned PFAS in food-contact paper/board (2020). US FDA ongoing PFAS phase-out from food contact notifications. California AB 1200 prohibits intentionally added PFAS in food packaging (effective 2023). Washington State bans PFAS in food packaging (2023). New York, Maine, Connecticut, Vermont, Minnesota all enacted PFAS food packaging bans. FDA BPA indirect food additive regulations (21 CFR 175-178).
corporate_fare Enterprise Interest
No enterprise interest recorded yet. Companies can indicate their volume and urgency to help guide research priorities.
flag Success Criteria
Kit test rating of 6 or higher (comparable to commercial PFAS-free alternatives, vs. 10-12 for PFAS). Cobb60 value below 20 g/m2 (good water resistance). No oil strike-through after 30 minutes of contact with olive oil at room temperature. Paper remains repulpable — fiber dispersion in water within 30 minutes of soaking. Formaldehyde-free per TAPPI T571.
precision_manufacturing Equipment Needed
Mayer rod/drawdown bar set, forced-air oven, TAPPI Kit test reagent set (castor oil, toluene, n-heptane per T559), Cobb test apparatus (TAPPI T441), analytical balance, kraft paper (unbleached, 70 gsm), timer, fume hood, stainless steel trays, ruler, graduated cylinders, pH meter
