Grease-resistant paper and paperboard in fast food and food delivery packaging is frequently treated with PFAS (per- and polyfluoroalkyl substances) to prevent oil and moisture penetration — the same DWR chemistry used in outdoor gear and stain-resistant upholstery is applied to food contact paper to create greaseproof barriers. When PFAS-treated food packaging contacts hot, fatty food (french fries, pizza, fried chicken), PFAS migration from the packaging into the food is accelerated by both temperature and fat content. The 2019 EWG and 2022 academic studies found total fluorine (a proxy for PFAS treatment) in paper food packaging from virtually every major fast food chain tested, with McDonald's, Burger King, and others showing positive detections. The transition to PFAS-free packaging has accelerated since these studies but remains incomplete.","synthesis":{"derived_risk_level":"moderate_to_high","synthesis_confidence":0.579,"synthesis_method":"compound_composition","context_used":"human_child","context_source":"product_users","exposure_modifier":1.2,"vulnerability_escalated":true,"escalation_reason":"Child exposure group","compounds_resolved":6,"compounds_total":6,"synthesis_date":"2026-05-09","synthesis_version":"1.2.0","methodology_note":"exposure_modifier and adjusted_magnitude are computed from ALETHEIA-calibrated heuristics (route × duration × frequency multipliers, clamped to [0.5, 1.4]).
