The Hidden Dangers Behind 'Convenience'

Paper cups that we hold dozens of times a day.

But inside, there is an 'invisible poison' lurking.

With 3 billion used annually in Korea, there may be a price to pay for convenience.

The 'Plastic Bomb' Awakened by Hot Beverages

The inside of disposable paper cups is coated with a thin layer of polyethylene (PE) or polypropylene (PP) to prevent leakage.

If you pour 95°C water into a paper cup and leave it for 20 minutes,

hundreds to thousands of microplastics leach out from the inner coating.

These particles are invisible to the naked eye, but they enter the body.

"The longer the exposure to high temperatures, the more explosively the amount released increases."

Nano Particles Disrupting Immunity and Hormones

According to research in Korea,

when hot water is poured into a paper cup coated with polyethylene,

plastic particles as small as one hundred-thousandth the thickness of a strand of hair (nanometer scale) are detected.

These micro particles can trigger inflammatory responses in immune cells and disrupt hormones.

In particular, ultra-fine nano-sized particles are more likely to accumulate in the body.

"When microplastics enter the human body through food or beverages,

there is a possibility of increased immune response and oxidative stress." - WHO

The Shadow of PFAS, the 'Forever Chemicals'

Some paper cups are waterproofed with PFAS (per- and polyfluoroalkyl substances).

Once these substances enter the body, they are hardly broken down and tend to accumulate,

and studies have reported that people with higher blood PFAS concentrations are at greater risk for hypertension and other diseases.

"Leaving hot beverages in paper cups for extended periods or reusing them accelerates damage to the coating layer, increasing exposure."

"Using reusable cups whenever possible is the most practical preventive measure."

Small But Certain Actions

By using a reusable tumbler,

the amount of microplastics is reduced to a quarter of that from paper cups.

Environmental issues cannot be overlooked either.

Because paper cups are made of both paper and plastic, they are nearly impossible to recycle,

and discarded cups eventually break down into microplastics, polluting soil and oceans.
