Are chemicals in food wrapping migrating into lunch meat?

What's actually in it

Food packaging is rarely just a simple barrier. It is a complex mix of chemicals designed to keep food fresh or prevent sticking. When you wrap lunch meat in plastic or paper, those materials can shed substances directly into your food. These are not inert materials. They are active mixtures that can move from the packaging into what you eat.

What the research says

A 2026 study in J Hazard Mater performed a screening of substances migrating from plastic and paper food contact materials. The researchers used computer modeling to predict toxicity and found that various chemicals move from the packaging into the food. This peer-reviewed research highlights that we are often consuming substances that were never intended to be part of our meal.

Another 2026 study in Food Chem used high-resolution mass spectrometry to look at how chemicals transfer from plastic materials. The study confirmed that chemicals move from the packaging into food, especially when heat is involved. While lunch meat is often cold, the migration of these substances is a constant risk whenever food touches plastic or treated paper packaging.

The health impact of these chemicals is a growing concern. A 2026 study in Environ Int examined how exposure to a mixture of food-related chemicals can affect development. The study found that these mixtures can alter biological development, showing that the chemicals leaching from our food packaging are not just sitting on the surface of our meat. They are entering our bodies and potentially causing harm.
