Cold stamping foil manufacturer — mill-direct rolls for converters

What a cold stamping foil manufacturer actually makes

A cold stamping foil manufacturer produces multi-layer metallised PET film built for UV-adhesive transfer at press speeds of 150–450 m/min. The stack is engineered layer by layer, not converted from off-the-shelf laminate.

• PET carrier (12, 19 or 23 µm) — mechanical backbone; 19 µm is the industry default for UV-flexo and UV-offset cold foil modules.
• Release coat — thermoset resin tuned to peel cleanly at 25–40 °C without heat, unlike hot stamping foil which requires 100–150 °C release.
• Colour / lacquer coat — pigmented or clear; carries Pantone Metallic tint or holographic embossed pattern.
• Vacuum-metallised aluminium — 300–500 Å thick, optical density 2.2–2.6, deposited under 10⁻⁴ mbar vacuum.
• Size coat (primer) — the surface that bonds to the UV cold-foil adhesive printed on the substrate.

How CFS's cold foil manufacturing line is built

The mill runs one 1.65 m wide vacuum metalliser (aluminium wire feed, water-cooled drum) feeding two 1.6 m gravure coaters — one for release + colour, one for size coat. Rewinding is on 76 mm (3") cores at up to 1,200 m/min, with in-line beta gauge for coat-weight control (target ±2 %).

Every jumbo is QC-sampled per lot: colour ΔE ≤ 1.5 vs master swatch (spectrophotometer, D65/10°), optical density ±0.05, adhesion ASTM D3359-22 rating 4B+, and metallising continuity by transmission photometer. Non-conforming jumbos are held and re-lotted, not shipped.

Manufacturing capacity, lead times and MOQs

• Standard stock shades (bright gold, pale gold, champagne, rose gold, copper, silver, holographic): 7–14 days ex-works after order confirmation.
• Custom Pantone Metallic pre-match: 3–4 weeks from colour approval; MOQ 3,000 lm per slit width.
• Holographic pattern development (new hologram origination): 6–8 weeks; MOQ 5,000 lm.
• Slit widths from 20 mm (narrow-web labels) to 1,600 mm (folding-carton sheetfed).

Compliance dossier — what ships with every lot

• REACH Annex XVII + SVHC candidate list (current 240 substances) — declaration signed per lot.
• RoHS 3 (EU 2015/863) — 10 restricted substances declared.
• EU 10/2011 food-contact regulation for plastic materials.
• FDA 21 CFR 175.105 — indirect food-contact adhesives (label + carton use), on request.
• California Prop 65 statement.
• Brand-side qualification packs prepared on request against the specific SKU and market.

Why buy from a manufacturer instead of a stockist

• Mill-direct price = 20–35 % below trading-house prices (source: internal customer benchmarking, 2025).
• Master pigment lot locked for 24 months — a stockist re-buys and re-blends, causing ΔE drift between reorders.
• Custom slit widths and short-length spools produced on the same machine that runs the jumbo — no third-party converter tolerance stack-up.
• Direct engineer contact for press-side troubleshooting (adhesive laydown, anilox BCM, cure energy).

How to order cold stamping foil from the mill

Ordering runs in four steps: qualify the shade on a sample roll, confirm slit width and core, approve the pro-forma, then schedule production. Most converters go from first enquiry to a qualified production order in three to five weeks, including a press trial on their own substrate.

• Step 1 — Sample: request a free 200–250 mm × 50–100 lm trial roll, or a full swatch book from the cold foil sample kit.
• Step 2 — Press trial: run the foil on your press with your UV adhesive; record anilox BCM, nip pressure and cure dose.
• Step 3 — Quote: send the quotation checklist data (shade, width, length, core, annual volume, destination port).
• Step 4 — Production: 7–14 days ex-works for stock shades, 3–4 weeks for custom Pantone Metallic pre-match.

OEM and private-label cold foil programmes

Beyond catalogue shades, the mill runs OEM programmes for distributors and large converters: neutral or customer-branded core plugs and carton labels, customer-specific lot numbering that feeds your ERP, dedicated master pigment lots held for repeat business, and consignment stock held in Wenzhou against a rolling forecast.

OEM programmes start at 20,000 lm per year across the SKU family and include a fixed technical contact plus a documented change-control procedure — no formulation change ships without written notice and retained reference samples.
