Perfluorinated grease-proofing agents are coatings on paper wrappers and containers that come into contact with food, such as fast-food wrappers, microwave popcorn bags, and pet food bags. These coatings prevent oil and grease from foods from leaking through the packaging. Perfluorinated grease-proofing agents in various forms have been used on food contact surfaces since the 1960s.
