Can plastic additives in your food increase your daily chemical intake?

What's actually in it

Plastic packaging contains phthalates, UV stabilizers, antioxidants, and plasticizers that help the material stay flexible, clear, and resistant to degradation. These chemicals aren't bonded permanently to the plastic. Over time, they migrate from the packaging into the food inside. The migration speeds up with heat, fat, and storage time.

Nearly every packaged food you buy has been in contact with plastic at some point, from processing equipment to the final wrapper on the shelf.

What the research says

A 2025 study in J Hazard Mater measured plastic additives in foods across different categories and calculated dietary exposure for children, teenagers, and adults. The results showed plastic additives in virtually every food tested, including dairy, meat, grains, and produce.

Children had the highest exposure per kilogram of body weight because of their smaller size and higher food intake relative to body mass. The study detected multiple additive types simultaneously in most foods, meaning people are exposed to complex mixtures, not single chemicals.

While individual chemical levels were often below regulatory limits, the combined daily intake from all food sources pushed some population groups close to or above safety thresholds. Reducing plastic food packaging at home, using glass storage containers, and buying fresh unpackaged foods when possible all help lower your daily dose.
