Custom Printed Peptide Vial Labels for Research & Cosmetic Vials

Peptide vials live in the coldest, most demanding packaging environment there is. Whether your product is a lyophilised research peptide stored at -20°C, a reconstituted solution held at 2°C–8°C, or a cosmetic serum vial, the label has to stay glued, stay legible and stay premium through every temperature swing in the cold chain.

Well We Print produces custom printed peptide vial labels on freeze-proof synthetic film with cold-chain-rated adhesive, luxury hot gold foil stamping and optional tamper-evident construction. Die-cut precisely for 2ml, 3ml, 5ml, 10ml and 15ml vials, on rolls or sheets.

What You Get

Freeze-proof film and adhesive rated from +80°C down to -20°C
Cold-chain adhesion that survives condensation and freeze/thaw cycling
Precision die-cutting for 2ml, 3ml, 5ml, 10ml and 15ml vials
Luxury gold foil, holographic and tamper-evident finish options
Batch number, lot, expiry, CAS and QR code variable data printing
Free digital proof before production

Freeze-Proof & Cold-Chain Adhesion (2°C–8°C / -20°C)

Standard room-temperature adhesive is the number one cause of label failure on peptide vials. At low temperature the adhesive turns glassy, loses tack, and the label pops off the curved glass wall — often while the vial is still inside the freezer box.

Engineered for Freeze / Thaw Cycling

Our cold-chain adhesive keeps a high initial tack at low temperature and stays permanently flexible, so it bonds firmly the moment it touches the vial and never embrittles. The construction is validated for refrigerated storage at 2°C–8°C and frozen storage at -20°C, including repeated transitions between the two.

Condensation & Moisture Resistant

Pulling a vial out of the fridge creates instant condensation. Because the face stock is synthetic film rather than paper, the label does not wrinkle, cockle or disintegrate — and the print does not run.

Cryo-Safe Material Comparison

Condition	Standard Paper	Standard Gloss Film	Our Cryo BOPP
Room temperature (20°C)	OK	OK	Excellent
Refrigerated (2°C–8°C)	Edge lift	Partial lift	Excellent
Frozen (-20°C)	Falls off	Falls off	Excellent
Freeze / thaw cycling	Fails	Fails	Passes

Standard Vial Sizing Chart

Vial labelling is unforgiving — a millimetre too tall and the label collides with the crimp or the rubber stopper. These are the die sizes we produce most often. Custom dimensions are welcome at no extra tooling cost.

Vial Size	Typical Diameter	Label Size (mm)	Label Size (in)	Recommended Finish
2ml vial	16 mm	35 × 15 mm	1.38 × 0.59 in	Gloss or gold foil
3ml vial	16–18 mm	40 × 18 mm	1.57 × 0.71 in	Gloss or gold foil
5ml vial	20–22 mm	50 × 22 mm	1.97 × 0.87 in	Gold foil or matte
10ml vial	22–24 mm	60 × 28 mm	2.36 × 1.10 in	Gold foil
15ml vial	25–28 mm	75 × 32 mm	2.95 × 1.26 in	Gold foil or matte

Sizing tip: always leave 2–3mm clearance below the crimp and above the base radius. On wrap labels we recommend a 3mm self-overlap; our pre-press team sizes and proofs this for you automatically.

Luxury Gold Foil & Tamper-Evident Finishes

Hot Gold Foil Stamping

Genuine metallic foil stamped into the label surface gives a true mirror-gold reflection that metallic ink cannot match. On film stock foil stays sharp on hairline type and micro-logos, so your brand mark reads as laboratory-grade luxury. Silver, rose gold, copper and holographic foils are also available.

Tamper-Evident Construction

We can build a tamper-evident label that spans the vial body and the cap, or a security seal positioned under the crimp. When the vial is opened, the label destructs cleanly and visibly, proving the product has not been interfered with. This is the preferred option for high-value peptide and cosmetic vials.

Matte and Gloss Print

Matte soft-touch film hides fingerprints and reads clinical and understated. Gloss maximises colour saturation and wipe-down durability. Both can be combined with foil on the same label.

Frequently Asked Questions (FAQ)

Will the labels stay on in a -20°C freezer?

Yes. Our cryo-rated adhesive and synthetic film are specified for continuous frozen storage at -20°C and for repeated freeze / thaw cycling, with no edge lift or fall-off.

Do you support variable data such as batch numbers and QR codes?

Yes. We print sequential batch and lot numbers, expiry dates, CAS numbers and scannable QR or Data Matrix codes, either in-line or as individually printed variable data.

Can I get a tamper-evident seal?

Yes. We produce tamper-evident vial labels and cap seals that destruct visibly on opening. Tell us your vial and cap dimensions and we will spec it.

Can you match a specific PMS or brand colour?

Yes. We match Pantone and CMYK references, and gold foil is available in several gold tones so you can align the foil to your brand.

What is the minimum order quantity?

We support both short trial runs and large volume production. The listed price reflects our standard configuration — request a quote with your vial size, quantity and finish for exact pricing.

Will I see a proof before printing?

Always. Every order includes a free digital proof, and we only print once you approve it.
