Are phthalates in food wrapping transferred to cheese and deli meats?

What's actually in it

Plastic food wraps and containers are not just sitting there doing nothing. They contain phthalates, which are chemicals added to plastic to make it soft and flexible. These chemicals are not chemically bound to the plastic, which means they can easily leak out.

When you wrap cheese or deli meats in plastic, these chemicals move from the packaging into your food. This is a process called migration. Once the chemicals are in your food, you ingest them.

What the research says

Research confirms that plastic materials release harmful substances into the items they hold. A 2026 study in J Hazard Mater performed an integrated screening of plastic-based food contact materials and found that various substances migrate from these materials into food.

The problem is not limited to just one type of container. A 2026 study in J Environ Sci Health B documented the migration of phthalates and other chemicals from plastic-based beverage cups. This confirms that these chemicals do not stay inside the plastic.

The health risks of these exposures are clear. A 2026 study in Environ Res linked repeated exposure to phthalates and their mixtures to metabolic syndrome in women. When you use plastic to wrap your food, you are increasing your daily intake of these endocrine-disrupting chemicals.
