A Priority Product is a product-chemical combination that meets these criteria:
• There are potential exposures to a Candidate Chemical in the product
AND
• One or more exposures have the potential to contribute to or cause significant or widespread adverse impacts

Scope of product: Food packaging materials
Any product containing PFASs placed into commerce in California that may be marketed or sold for the purpose of:
• making paper, paperboard, or molded fiber resistant to oil, grease, and water; or
• releasing the molded fiber food packaging products from the formation mold

Scope of Candidate Chemical: Perfluoroalkyl and polyfluoroalkyl substances (PFASs)
PFASs are a class of nearly 5,000 man-made chemicals with at least one fully fluorinated carbon atom.
All are Candidate Chemicals for the SCP program, due to listing by Biomonitoring California as Priority Chemicals in 2015.

Presence in Products
There are currently 30 approved notifications for use in food contact substances under the FDA regulations. • This accounts for 19 distinct PFAS compositions from six manufacturers.
Products are common in California homes and workplaces: • Paper and paperboard products including bakery bags, deli wrappers, microwave
popcorn bags, french fry boxes, takeout containers, and pizza boxes.• Molded fiber products including bowls, soup containers, clamshells, plates, and
food trays.
