Pet Food Packaging Migration (BPA Can Liner, Phthalate in Flexible Packaging, PFAS in Grease-Resistant Treat Bags) — pet safety profile
Moderate riskPet food packaging is a significant source of chemical migration into food — particularly canned pet food, flexible pouches, and grease-resistant treat bags.
What is this product?
Pet food packaging is a significant source of chemical migration into food — particularly canned pet food, flexible pouches, and grease-resistant treat bags. BPA-based epoxy linings remain common in pet food cans — unlike human food cans where BPA-free alternatives have gained 90%+ market share, pet food cans have lagged in transition. A 2017 study (Sci Total Environ) found BPA levels of 13-136 ng/g in canned dog food, with a 2-week canned diet feeding study showing a 3-fold increase in serum BPA levels in dogs. DEHP and DINP phthalates are used in flexible packaging (pouches, resealable bags) at concentrations of 0.1-1.0% by weight. PFAS (per- and polyfluoroalkyl substances) are used as grease-resistant coatings in pet treat bags — a 2022 Environmental Science & Technology Letters study detected total fluorine levels of 10-4,500 ppm in pet food packaging, with 45% of samples exceeding 20 ppm (indicative of intentional PFAS treatment). Pets consume the same packaged food daily for months to years — far more uniform exposure than human diets. No FDA guidance specifically addresses packaging migrants in pet food, creating a regulatory gap.
