In the medical industry, labels are often overlooked — yet they are critical.
From pharmaceutical packaging to medical devices and laboratory samples, every label must remain clear and readable under demanding conditions. One of the most common challenges is alcohol wiping.
A client in the medical consumables sector faced exactly this issue.
Their products require frequent disinfection during use. This means labels must not only be clear, but also remain intact after repeated exposure to alcohol.
Their initial solution used standard resin ribbons. The print quality was acceptable at first, but problems quickly appeared in real-world use:
After several alcohol wipes, barcodes began to fade.
Text became blurred.
In some cases, parts of the print even peeled off.
In a medical environment, this is unacceptable.
They then tested SINOCO’s SNR3300, paired with matte silver PET material.
The test was straightforward — and rigorous:
Repeated wiping of the same label area using alcohol pads, over multiple cycles.
After the first wipe — no change.
After the third — still clear.
Even after the tenth cycle, barcode edges remained sharp, with no spreading or fading.
In further testing, SINOCO’s metallic ribbon series demonstrated equally stable performance. Whether silver, gold, or other metallic finishes, the prints maintained strong adhesion and visual integrity even after alcohol exposure.
For many industries, this goes far beyond durability.
In medical, laboratory, and even high-end cosmetics applications, labels are not just carriers of information — they represent reliability and safety.
If critical information becomes unreadable due to wiping, it can lead to misidentification and potentially serious consequences.
After completing validation, the client quickly implemented SINOCO solutions across multiple product lines. The most immediate results were clear:
Fewer label-related complaints.
Smoother internal quality control processes.
Their conclusion was simple:
They didn’t choose it just because it prints clearly —
they chose it because it doesn’t fail under the toughest conditions.
Because for labels, true quality is not defined at the moment of printing —
it is proven after exposure, friction, and cleaning.
And that is exactly what SINOCO ribbons are designed to deliver from the very beginning.
