What’s Really in Your “Paper” Coffee Cup

Ever wondered why your takeaway coffee cup never leaks?
The truth is a bit shocking: it’s not just paper. Every “paper” cup is lined with a thin layer of plastic.

And when hot liquid (like your coffee) hits that lining, it starts to break down - releasing microplastics, heavy metals, and toxins straight into your drink.

What’s really inside your cup?

That morning flat white might be serving you more than caffeine. Studies have found that the chemicals released from the plastic lining into your drink include:

• Ions like fluoride, chloride, sulphate, and nitrite.
• Microplastics - a study from IIT Kharagpur found more than 25,000 particles were released from a single cup within 15 minutes. 
• Heavy metals including lead, chromium, and cadmium.

These particles are ingested with your coffee, and once inside your body, they can travel through your system - even reaching the brain. Studies have linked this exposure to:

• Hormone disruption
• Fertility problems
• Metabolic changes and weight gain
• Increased cancer risk

Plastic lids? Just as concerning.

Think the plastic lid is harmless? Think again.
Black recycled plastic lids are often made from old electronics — meaning they contain flame retardants and other chemicals tied to hormone disruption and cancer.

Now think about it: even sipping from one of these cups once a week can add up to significant exposure over the years.

A Simple Swap = Big Impact

Switch to a reusable stainless-steel cup, glass, or if you are at your local coffee shop, even a ceramic mug.

Better for You, Better for the Planet

Reusable cups aren’t just an eco-friendly choice - they’re a health choice.
