New year, new you, right? As kids gear up for the schoolyard and adults head back to the office, it’s time to shake things up—including the way we pack lunches. But before you reach for that trusty plastic lunchbox or sandwich bag, let’s talk about some not-so-friendly companions lurking in your food storage: PFAS and microplastics.

These “forever chemicals” might be small, but they’re causing big problems for our health and the environment. Ready to learn more? Let’s dive in…

What Are PFAS, and Why Should You Care?

PFAS (Per- and polyfluoroalkyl substances) are a group of man-made chemicals known for their water- and grease-resistant properties. Found in non-stick cookware, waterproof fabrics, and yes, even plastic food storage, these chemicals have earned the nickname “forever chemicals” because they don’t break down naturally.

Here’s the kicker. Recent research has shown that PFAS can leach from plastic containers and bags into your food, especially when exposed to heat or wear and tear. This means your “healthy” packed lunch might come with a side of unwanted toxins.

Health Impacts: The Invisible Threat

Studies have linked PFAS exposure to a host of health issues, including hormonal imbalances, immune system suppression, and even increased risks of certain cancers. Microplastics—tiny plastic fragments often carrying PFAS—can damage human cells, leading to inflammation and oxidative stress. It’s not just a bad day for your body; it’s a long-term health concern.

And let’s not forget the cumulative effect. Chemicals from food packaging, including PFAS, can build up in our bodies over time. The result? A chemical cocktail none of us ordered.

"Harmful effects on cells are in many cases the initiating event for health effects. We should be concerned." - research published in the Journal of Hazardous Materials. 

The Environmental Ripple Effect

PFAS aren’t just bad news for humans. They’re wreaking havoc on our planet too. These chemicals seep into soil and water, contaminating ecosystems and harming wildlife. Microplastics, often carrying PFAS, have been found in some of the most remote places on Earth. If this doesn’t make you cringe, imagine your sandwich bag taking an all-expenses-paid trip to the Arctic—and staying there forever.

Still Using Plastic Containers? Here's How to Prevent Them from Leaching into Your Food

Many of us have plastic containers we have used for years. If possible, avoid using it for food storage. Instead, repurpose it for non-food items like toys, LEGO pieces, craft supplies, stationery, or electronics. By keeping plastic away from food, you can minimise exposure to microplastics and harmful forever chemicals

If you still use it for food storage, here are some steps  to reduce the risk of forever chemicals and microplastics leaching into your food:

1. Avoid Heat: Never microwave food in plastic containers. Heat can break down the plastic, releasing harmful chemicals. Learn more here. Instead, transfer food to glass or ceramic for heating.
2. Skip the Dishwasher: Handwash plastic containers with mild soap and cool water. Dishwashers’ high heat can cause wear and tear.
3. Get Rid of Damaged Containers: If you notice cracks, scratches, or cloudiness, it’s time to let them go—these are signs that the plastic is breaking down. It’s time for a safe and eco-friendly upgrade!
4. Store Food Wisely: Use plastic for dry, non-acidic foods, as wet, oily, or acidic items are more likely to encourage chemical leaching.
5. Switch Gradually: Transition to stainless steel, glass, or premium silicone containers over time. They’re safer, last longer, and are better for the planet.

• Taking care of the plastic you already own is a great start while working toward more sustainable choices! 

Time to Switch: PFAS-Free Food Storage

The good news? You can ditch PFAS and microplastics for good by opting for safer, eco-friendly food storage options. Here are four safe choices for food storage: 

1. Stainless Steel Containers - Durable, non-toxic, and long-lasting.

• • Stainless steel doesn’t leach harmful chemicals like plastic can, ensuring your food stays safe. It's also easily recyclable and maintains food freshness without absorbing odours or stains. Find some options here.

2. Glass Containers - Non-toxic and free from harmful chemicals.

• • Glass is a great choice because it won’t absorb food odours or colours, and it’s microwave and dishwasher-safe. It’s perfect for storing both dry and wet foods, and it’s highly reusable.

3. Food Wax Wraps -An eco-friendlyalternative to plastic wraps and bags.

• • These wraps last you a year and are made from natural materials like (bees)wax, organic cotton, and tree resin. They keep food fresh and are perfect for wrapping sandwiches or covering bowls. We LOVE this Australian-made brandhere.

4. Premium Silicone Food Storage - Flexible, durable, and long-lasting.

• • Silicone storage bags and containers are safe for both food and the environment. They’re non-toxic, reusable, and can withstand high and low temperatures, making them ideal for storing leftovers, snacks, and even liquids. See our premium options here and silicone takeaway boxes here

Switching to these alternatives isn’t just about better health; it’s about taking a stand for a cleaner planet. Plus, they’re ridiculously good-looking. Form and function? Yes, please!
