What food packaging contains PFAS?

Per- and poly-fluoroalkyl substances, more commonly known as PFAS, are a group of chemicals with properties that make them extremely effective at resisting heat, grease and water properties that make them seemingly ideal for use in the food packaging industry. 

But these same characteristics also make PFAS highly persistent in the environment and the human body, causing concern among health and environmental advocacy groups.

In this section, we delve into the issue of PFAS in food packaging, identifying where it is most commonly found, potential health risks and efforts to reduce our exposure to these chemicals.

PFAS in Food Packaging

PFAS is commonly found in a variety of food packaging materials due to their oil and water resistance. These include microwave popcorn bags, pizza boxes, sandwich wrappers, pastry bags and other fast food packaging.

Additionally, they can be found in non-stick cookware and certain types of food storage containers. It’s important to note that the use of PFAS is not limited to these examples and they can be found in a broader range of products.

Awareness and mindfulness of product choices can significantly help in reducing exposure to these persistent chemicals.

Health risks associated with PFAS

Exposure to PFAS can occur through ingestion, inhalation and skin contact. Once inside the body, these chemicals can accumulate in various organs and tissues, leading to potential health risks.

Studies have linked PFAS exposure to a range of health issues such as immune disorders, thyroid disease, kidney and testicular cancer and developmental effects on infants and children. Additionally, PFAS have been found to interfere with hormonal and metabolic processes in the body, leading to potential long-term health effects.

The most concerning aspect of PFAS is their ability to accumulate in the body over time, as they are not easily broken down or eliminated. Therefore, even low levels of exposure can lead to adverse health effects.

Common Food Packaging Containing PFAS

PFAS are prevalent in a variety of food packaging materials owing to their grease and water-resistant properties.

This includes but is not limited to:

• Fast food wrappers and containers: These include wrappers for burgers, sandwiches, tacos and fried foods. Tray liners and french fry containers are also common culprits.
• Microwave popcorn bags: The inner lining of these bags is often coated with PFAS to prevent oil and butter from seeping through.
• Pizza boxes: PFAS are used in pizza boxes to prevent grease stains and to retain heat.
• Non-stick cookware: Many non-stick pots, pans and baking sheets use PFAS compounds to prevent food from sticking.
• Certain food storage containers: Some plastic containers and lids, particularly those advertised as being stain-resistant or non-stick, may contain PFAS.

In all these instances, PFAS can migrate from the packaging or cookware to the food, especially when the food is hot, greasy or acidic.

Therefore, being mindful of the types of food packaging and cookware we use can significantly help in reducing exposure to these persistent chemicals.

Efforts to reduce PFAS in food packaging

In recent years, there has been a growing concern about the use of PFAS in food packaging and its potential health risks. As a result, some companies have begun to phase out their use of these chemicals voluntarily.

Additionally, regulatory agencies are taking steps to address this issue by proposing bans or restrictions on the use of PFAS in certain food packaging materials. For example, in 2020, the US Food and Drug Administration (FDA) announced a ban on the use of PFAS in grease-resistant food packaging, citing potential health risks.

Moreover, consumers can also play a role in reducing their exposure to PFAS by choosing products that do not contain these chemicals. Look for labels such as “PFAS-free” or opt for greener, more sustainable packaging options.

Overall, it is essential to raise awareness about PFAS and its presence in food packaging and take necessary steps to reduce our exposure for the sake of our health and the environment. So, be mindful of your choices and choose wisely.

Alternatives to PFAS in the packaging industry

The packaging industry is actively seeking alternatives to PFAS to minimize potential health and environmental risks. Some of these alternatives include:

1. Plant-based materials: Packaging made from materials like cornstarch, mushroom roots and seaweed are not only biodegradable but also free of harmful chemicals like PFAS.
2. Waxed paper or cardboard: These materials are naturally resistant to moisture and grease, making them a viable alternative for certain types of food packaging.
3. Silicone-based materials: Silicone, a flexible and heat-resistant material, is increasingly being used in place of PFAS in cookware and baking utensils.
4. Innovative coatings: Some companies are developing coatings that mimic the water and grease-resistant properties of PFAS without the associated environmental and health risks.

FAQs – PFAS in Food Packaging

What is PFAS and why is it used in food packaging? 

PFAS or Per-and polyfluoroalkyl substances, are a group of man-made chemicals that have been used in a variety of industries due to their resistance to heat, water and oil. These properties make them ideal for use in food packaging to prevent leaks and stains.

How can PFAS get into our bodies from food packaging? 

PFAS can migrate from the packaging to the food, especially when it’s hot, greasy or acidic. They can then be ingested with the food.

Additionally, PFAS can also be absorbed through the skin when in contact with packaging or cookware containing these chemicals.

What are the health risks associated with PFAS exposure? 

Studies have linked PFAS exposure to a range of health issues such as immune disorders, thyroid disease, kidney and testicular cancer and developmental effects on infants and children.

They can also interfere with hormonal and metabolic processes in the body, potentially leading to long-term health effects.

How can I reduce my exposure to PFAS from food packaging?

• Consider using alternatives to PFAS-containing packaging whenever possible, such as waxed paper or cardboard.
• Check labels for “PFAS-free” products or opt for greener, more sustainable packaging options. 
• Avoid using non-stick cookware and consider switching to silicone or ceramic options.
• Be mindful of the types of foods you choose to consume, as certain food types may be more likely to contain PFAS due to their packaging.

Wrap Up

It’s crucial to be aware of what food packaging contains PFAS and the potential risks associated with these chemicals. While the use of PFAS has been widespread for decades, we are now starting to see the detrimental effects on our health and environment.

The good news is that there are steps we can take as consumers to minimize our exposure, such as avoiding certain types of packaging and opting for safer alternatives. 

There is also a growing movement towards stricter regulations and bans on PFAS in food packaging. However, it’s important for us to stay vigilant and demand transparency from companies about their packaging materials.
