Which common food packaging items are treated with PFAS to prevent grease soak-through?

Fast-food wrappers, microwave popcorn bags, and pizza boxes

The integration of PFAS into consumer life extends significantly into food contact materials, driven by the need for grease and moisture resistance. Specifically, many food service items that handle fatty or greasy foods utilize PFAS coatings to prevent the liquid or grease from penetrating the paper or cardboard packaging. The key examples cited for this application include the wrappers used for fast food, the specialized bags designed for microwave popcorn, and the boxes used for pizza. This application creates a direct pathway for potential chemical ingestion because the PFAS coating comes into direct contact with the food item, allowing trace amounts to transfer when the food is consumed.
