What Is BPA and Why Should You Care?
Bisphenol A — BPA — is a chemical compound used in the coating of thermal paper. It's what makes the paper react to heat and produce an image without ink. Every time a thermal printer produces a label, the paper it prints on contains BPA on its surface. That includes FNSKU labels, shipping labels, and the barcodes that go on every unit sent to Amazon.
BPA is an endocrine disruptor. That means it can interfere with your hormones. Research has linked prolonged exposure to a range of health concerns, and while the science is still developing around exactly how much exposure causes problems, the consensus in occupational health is clear: if you're handling thermal paper regularly, you should be taking precautions.
For someone selling a few units a month from their spare room, this probably isn't keeping them up at night. But in a prep centre environment where staff are printing and applying hundreds or thousands of labels a day, the exposure adds up. It's not a one-off — it's sustained, repeated skin contact with BPA-coated paper throughout every working shift.
Why This Matters in FBA Prep
Think about the daily workflow in a prep centre. Labels are printed in bulk. Staff peel them, apply them to products, handle misprints, sort through label sheets, and do this for hours on end. Hands are in constant contact with thermal paper. If you've ever noticed your fingers feeling slightly slippery or coated after handling a stack of thermal labels, that's the BPA coating transferring to your skin.
The concern isn't a single label. It's the cumulative exposure over days, weeks, and months. Studies have shown that BPA absorbs through the skin, and that handling thermal paper is one of the most significant routes of occupational BPA exposure. When you combine that with the volume of labels a prep centre gets through, it becomes a genuine workplace health consideration.
What Most Sellers Don't Realise
If you're doing your own prep at home, you're probably not thinking about this at all. You print your labels, stick them on, and move on. And for low volumes, the risk is minimal. But it's worth knowing that the paper you're handling isn't just paper — it's chemically coated, and prolonged bare-skin contact isn't ideal.
It's also worth considering when you're choosing a prep centre. The way a business treats its staff says a lot about how it operates. If a prep centre hasn't thought about something as basic as protecting their team from chemical exposure, what else are they cutting corners on?
How Precision Handles This
At Precision, we take this seriously. Our staff handle thousands of thermal-printed labels every week, and we've put proper measures in place to protect them.
Everyone on the prep floor wears nitrile gloves when handling labels. Nitrile is the right material here — it provides an effective barrier against BPA transfer, unlike latex which doesn't block it as well. Gloves are changed regularly throughout the day, and fresh pairs are always available at every workstation.
We also maintain good hand hygiene practices. Staff wash their hands before breaks and after label handling sessions, even with gloves on. It's about building habits that reduce exposure to the lowest level possible.
Why We're Talking About This
Honestly, nobody in the FBA prep space talks about BPA exposure. It's not glamorous. It doesn't help you rank on Amazon or find your next winning product. But it matters.
Running a prep centre means being responsible for the people who work in it. That's not something we take lightly. When your stock arrives at Precision, it's being handled by a team that's looked after properly — with the right equipment, the right training, and the right environment to do the job safely.
That might seem like a small thing, but it's part of running a professional operation. And professionalism shows up in everything we do, from the way we handle your stock to the accuracy of your shipments.
