Waterproof vial labels, and where the word actually applies
Buyers search for waterproof vial labels. What they need is a label that survives a vial coming out of the refrigerator, an alcohol wipe, and a week in a drawer. Our BOPP and film stocks do that. They are water-resistant, not waterproof, and this page draws the line honestly so you can pick the right stock.
Printed inline in full color, no plates or plate fees, 50 labels per design, digital proof before the first run.
Film stocks that shed water
White matte film (BOPP)
The default for vials. Biaxially oriented polypropylene does not absorb water, so condensation beads and wipes off instead of soaking in. Matte face takes pen and marker for write-in fields.
White gloss film
Same polypropylene body with a gloss face. Colors read more saturated and the surface wipes cleaner, at the cost of write-in fields, which smear on gloss.
Clear film
For a no-label look on dark art only. Our press prints CMYK without white ink, so light colors on clear go translucent. Same water resistance as the white films.
Freezer-grade adhesive
Cold performance is an adhesive property, not a face-stock property. Ask for the freezer-grade adhesive when vials live below zero. Apply to dry, room-temperature vials and let it set before chilling.
What the labels survive, and what they don't
| Condition | Film vial labels |
|---|---|
| Condensation after cold storage | Yes. The film face sheds it; cured pigment ink does not run. |
| Isopropyl alcohol wipe-down | Yes. Wipe, do not soak. Print and face hold up to routine wiping. |
| Gloved handling, drawer rub, shipping | Yes. Film resists abrasion in a way paper never will. |
| Refrigerator and freezer storage | Yes with the right adhesive. Standard acrylic to about 0 °C, freezer-grade below. |
| Immersion in water or solvent | No. Water-resistant, not waterproof. Nothing we print is rated for soaking. |
| Liquid nitrogen or vapor-phase cryo | No. Our press, ink, and media are not certified for cryogenic storage. |
Cold storage, without the word cryo
In lab vocabulary, cryogenic means liquid nitrogen, and we will not put that word on a label we cannot certify for it. What we do supply is a freezer-grade adhesive that holds on vials stored below zero, on a face stock that shrugs off the condensation that forms when the vial comes back out. For lyophilized peptides in a lab freezer, that is the combination most suppliers need. If your line goes into vapor-phase nitrogen, you need a certified cryo label from a specialist, and we will say so on the quote rather than sell you the wrong thing.
Why paper fails on a vial
Paper wicks. One pass through a refrigerator door and the edges soften, the ink feathers, and a barcode that scanned on the proof stops scanning on the bench. Film costs a little more per label and removes the whole failure mode. The vial materials guide walks through every stock we carry and where each one belongs.
Ordering film vial labels
Pick a size from the sizing table, choose white matte film unless you have a reason not to, and tell us the storage temperature on the quote form so we match the adhesive. Every first run gets a digital proof where fit, variable data, and code scannability are checked before anything prints. Reorders skip the proof.
