A recent study reveals that about 1,000 tons of microplastics from packaging make their way into our food each year. Some of these particles are tiny enough to enter our cells, raising concerns about how they might interact with our biology.
The research, titled Pack to Plate, was conducted by Earth Action in collaboration with rePurpose Global. It highlights specific types of packaging that are especially risky, such as caps, closures, and foodservice trays, which can allow particles to migrate into food.
Julien Boucher, co-CEO of Earth Action, shared insights on these findings. He pointed out that areas like caps and seals are crucial because their design can significantly reduce the release of microplastics. “We need to create packaging that holds more product while using less material,” he emphasized. He also advocates for testing packaging under realistic conditions, such as repeated handling and heating, rather than just initial use scenarios.
The presence of microplastics in our bodies is alarming. Research has found microplastics in human brains and stomachs, as well as in IV drips and agricultural soil. This raises serious questions about health implications.
The report highlights that microplastics migration isn’t random. It’s influenced by material choice, design, and real-world conditions. For instance, PET bottles are responsible for about 28% of microplastic exposure, followed by rigid PET and flexible PE. Together, they make up over half of the total emissions.
Boucher notes that most opportunities to reduce these emissions lie with manufacturers and supply chain operators. He recommends practical measures, such as minimizing UV exposure during storage and transportation, which can encourage particle release.
Interestingly, while packaging isn’t the largest source of microplastics, its direct contact with food leads to a higher concentration of exposure compared to other environmental sources.
The study also points out that consuming microplastics can expose us to harmful chemicals. Current regulations often don’t account for this risk, which is concerning. Boucher argues for a shift in food-contact material regulations; they should evaluate the packaging as a whole, not just based on the type of polymer used.
In response to growing concerns, the European Commission recently issued guidance to help implement new packaging regulations in the EU. However, industry experts feel that these guidelines don’t adequately address issues like PFAS compliance.
To improve safety, Earth Action recommends that approval processes for packaging must include testing for realistic conditions. They propose setting limits on microplastic emissions for high-volume packaging types, starting with PET materials.
On a global scale, the proposed UN Global Plastics Treaty aims to establish more unified regulations to protect both human health and the environment. In the U.S., the Department of Health and Human Services has initiated a $144 million research program to tackle microplastics, focusing on how to measure and remove them effectively from the body.
As awareness grows, it’s clear that reducing microplastic exposure is becoming a pressing issue for both health and regulatory frameworks.
