What makes cold foil stamping the right choice for pharmaceuticals?

Cold foil stamping is applied inline on the same flexo press that prints the artwork, which collapses the production timeline for pharmaceuticals from 7–10 days down to 36–48 hours. There is no heated die, no offline make-ready, and the foil can be overprinted with process inks in the same press pass — three things that hot stamping cannot match on a typical pharmaceuticals run.

Which substrates run best for pharmaceuticals?

The CFS technical team validates each foil family against the substrate window noted in the press parameters above. In production we routinely qualify SBS / GC1 pharma board 250–350 gsm on combination flexo presses with cationic UV adhesive at 2–4 g/m². Stocks outside that window — uncoated wine papers, soft-touch laminates, mono-material recyclable films — are handled with dedicated adhesive and primer setups.

Is cold foil decoration on pharmaceuticals packaging recyclable?

Yes. The transferred metal layer is approximately 0.05% of finished package weight — well below the 5% threshold under the EN 643 paper-for-recycling specification — so paper-based pharmaceuticals packaging carrying CFS cold foil remains recyclable in standard CEPI paper mills. Independent ISEGA and PTS Munich deinkability reports are available on request.

What lead time and minimum order should I plan for?

Standard production rolls (1,000 lm and up) ship in 5–7 working days from our European plants. For pharmaceuticals brand owners commissioning sample production through our converter network, the practical minimum is 5,000 units; below that we recommend a printed sample pack first so design intent can be validated on the target stock before tooling.

Security & Trust

Pharmaceuticals

Migration-safe cold foil for regulated pharma packaging.

Pharmaceutical packaging carries weight beyond aesthetics: it must reassure, authenticate, and survive global supply chains. CFS cold foil for pharma is formulated with low-migration UV adhesives compliant with EuPIA, Swiss Ordinance and Nestlé Guidance, and the holographic range supports custom diffraction patterns that double as covert anti-counterfeit marks. Cold-foil decoration runs inline with the standard flexo print of folding cartons, removing the hot-stamp step from a tightly-validated production line.

Quick answer

Cold foil stamping for pharmaceutical folding cartons uses low-migration UV adhesives (EuPIA, Swiss Ordinance Annex 10, Nestlé Guidance compliant), transferring silver or custom-diffraction holographic foil at 200–300 m/min on 250–350 gsm SBS/GC1 pharma board. Track-and-trace GS1 datamatrix, batch and expiry data overprint in the same press pass, keeping GMP-validated production lines short and auditable versus offline hot stamping foil steps.

The cold foil process

Three inline steps. One press pass.

Cold foil stamping is fundamentally different from hot stamping — it lives inside the flexo print line, not beside it. Here is how it works for pharmaceuticals.

1 — Low-migration adhesive

Compliant UV adhesive printed in the exact shape of the metallic / security artwork.

2 — Foil transfer

Standard silver or custom-pattern holographic foil transferred inline at flexo speed.

3 — Track-and-trace overprint

Variable data, GS1 datamatrix and serialisation overprinted in the same press pass.

Cold foil vs hot stamping foil

Cold foil vs hot stamping foil for pharma cartons

Side-by-side operating parameters for cold foil stamping and hot stamping foil on pharmaceuticals, using the substrate and press-speed window this vertical actually runs.

Attribute	Cold foil stamping (CFS)	Hot stamping foil
Process	UV adhesive printed → cold foil laminated → instant UV cure (ambient temperature)	Heated brass/magnesium die at 100–150 °C presses foil onto substrate, offline
Typical substrate window	Pharma SBS / GC1 board 250–350 gsm	Coated SBS/FBB; heat-sensitive films require special dies
Press speed	200–300 m/min	20–60 m/min (Kurz / Crocus benchmarks)
Tooling	Photopolymer flexo plate — hours, low cost	Etched brass/magnesium die — days, per-artwork cost
Inline overprint	Yes — CMYK/varnish overprint in same press pass	No — decoration happens after print, offline
VOC / m²	≈ 0 g/m² (100% UV-cure adhesive)	2–6 g/m² for solvent-adjacent finishing steps
Registration	±0.05–0.10 mm (servo combination presses)	±0.15–0.30 mm typical

Specifying the job

What to lock down before press.

Successful pharmaceuticals jobs share four upstream decisions: substrate and finish, foil family, adhesive coat weight and overprint sequence. Lock these in design review and the press run becomes a repeatable production task instead of a make-ready experiment. Our technical team publishes per-product run-sheets for each foil SKU so prepress, platemaking and the pressroom work from the same numbers.

On press, the variables that matter most are anilox cell volume (we recommend 8–12 cm³/m² for most pharmaceuticals work), UV lamp dose (350–500 mJ/cm² for cationic adhesives), nip pressure on the foil station, and web tension stability across the foil-transfer zone. Combination flexo presses from Bobst, Gallus, Nilpeter, MPS and Mark Andy all run our foil range out of the box; older machines may need a foil-station retrofit, which we can scope with your OEM.

For brand owners, the practical takeaway: send your dieline, intended substrate and a sample of a competitor finish you want to match or beat. We will return a printed sample pack on your stock, a recommended foil family, and a target run-sheet within 5 working days.

Quality control

Every production batch is checked on a Konica Minolta CM-26d spectrophotometer for L*a*b* consistency, plus inline 100% optical inspection for pinholes and edge definition. Tolerance bands and golden samples ship with each lot.

Sustainability

Foil supplied to pharmaceuticals customers is produced in plants running on 100% renewable electricity, with carrier-film take-back through our French recycling partner. Full ISO 14040/14044 LCA data is available on request. Read our sustainability brief.

Compliance

Products tested against EuPIA, Swiss Ordinance Annex 10 and Nestlé Guidance Note for low migration; FSC chain-of-custody available on paper-backed lines; REACH and RoHS declarations on every technical data sheet.
