What makes cold foil stamping the right choice for confectionery wrappers?

Cold foil stamping is applied inline on the same flexo press that prints the artwork, which collapses the production timeline for confectionery wrappers 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 confectionery wrappers run.

Which substrates run best for confectionery wrappers?

The CFS technical team validates each foil family against the substrate window noted in the press parameters above. In production we routinely qualify BOPP, PET, alu-laminated film 18–40 µm 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 confectionery wrappers 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 confectionery wrappers 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 confectionery wrappers 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.

High-Volume Premium

Confectionery Wrappers

Cold-foil chocolate and candy wrappers at full flexo throughput.

Confectionery wrappers are arguably the toughest test for any decoration process: thin metallised films, very high line speeds, tight unit economics and brand teams demanding ever-richer metallic palettes. Cold foil stamping was made for this. CFS foil transfers at 300+ m/min onto BOPP, PET and aluminium-laminated film without any heat distortion, and a single SKU of bright gold can be tinted inline into rose, copper, bronze and champagne — eliminating the foil-inventory bloat that hot stamping creates for seasonal and limited ranges.

Quick answer

Cold foil stamping transfers metallic decoration onto BOPP, PET and aluminium-laminated confectionery film 18–40 µm at 250–350 m/min on inline UV flexo, without the heat distortion that hot stamping foil (100–150 °C brass dies) causes on thin polymer webs. Tinted overprints build rose, copper, bronze and champagne palettes from a single base foil — repulpable / mono-material PE/PP variants are available for recyclable wrapper programs.

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 confectionery wrappers.

1 — High-speed flexo adhesive

UV adhesive printed on BOPP, PET or foil-laminated film at full production speed without web-tension penalties.

2 — Inline foil transfer

CFS foil transferred and UV-cured in one nip — no heat, no film distortion, no slowdown.

3 — Tinted overprints

Process inks printed over the foil to build rose-gold, copper, bronze and bespoke metallic shades from a single base foil SKU.

Why cold foil for confectionery wrappers

Cold foil vs hot stamping foil

Cold foil vs hot stamping foil for confectionery wrappers

Side-by-side operating parameters for cold foil stamping and hot stamping foil on confectionery wrappers, 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	BOPP, PET, alu-laminated film 18–40 µm	Coated SBS/FBB; heat-sensitive films require special dies
Press speed	250–350 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 confectionery wrappers 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 confectionery wrappers 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 confectionery wrappers 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
