Cold Foil Manufacturer and Supplier for Packaging 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).

For color development, physical approval and RFQ details, see custom Pantone-referenced cold foil.

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.

What should buyers check when comparing cold foil manufacturers?

Compare cold foil manufacturers on consistency first, then on the practical supply details. Shade drift between lots, available roll widths and adhesive compatibility cause far more production trouble than headline price. Sample support, lead time and technical documentation decide how quickly a new grade reaches production.

A useful shortcut when comparing cold foil suppliers: send the same substrate and press detail to each candidate and see who asks follow-up questions. A supplier that quotes a grade without asking about your adhesive and cure output is quoting from a catalogue, not for your job.

• Product consistency — ask whether the master pigment lot is retained and how shade is verified between production lots.
• Roll width and core — confirm the supplier slits to your exact web width rather than expecting you to re-slit.
• Colour and effect range — check that silver, gold, champagne, copper and holographic grades come from one source, so a design change does not mean a new supplier.
• Adhesive compatibility — the release grade must match your UV cold foil adhesive and cure output, not just the press type.
• Sample support — free swatch books and trial rolls slit to width, and a willingness to review your press results.
• Lead time — separate the stock-shade lead time from custom colour matching, which always takes longer.
• Technical documentation — datasheets, certificates of analysis and compliance declarations matched to the lot supplied.

Cold foil suppliers vs direct cold foil manufacturers

A trading stockist holds inventory and resells it; a direct manufacturer coats, metallises and slits the material. For one-off or small quantities of a standard shade, a stockist is often faster. For repeat production, custom colour or any job where lot-to-lot consistency matters, buying from the manufacturer removes a layer of variability and a layer of margin.

The practical difference shows up on the second order. A stockist re-buys from whichever mill has stock, so the shade and release behaviour can shift without notice. A manufacturer holds the formulation and the retained reference sample, so a repeat order can be matched against the lot you already approved.

There is also an engineering difference. When a press trial goes wrong, a manufacturer can change carrier gauge, release grade or lacquer and re-run a trial roll. A stockist can only offer a different item from stock.

Cold foil manufacturer in China for export packaging projects

CFS is a China-based cold foil manufacturer and supplier, producing and slitting cold stamping foil in Wenzhou, Zhejiang, and exporting to converters worldwide. We do not manufacture in Europe or North America; overseas customers are served by direct export shipments and by technical support in English on their own press data.

For export projects the practical questions are documentation, lead time and freight. Sample rolls move by express courier in a few days; production quantities ship by sea freight, and destination terms are agreed per order. Compliance declarations are prepared against the specific SKU and destination market rather than issued as a generic pack.

• Manufacturing and slitting in Wenzhou, Zhejiang, China — no third-party converting step between coating and your roll.
• English-language technical contact who reviews your anilox, nip and cure data, not just the order line.
• Compliance declarations prepared per SKU and destination market on request.
• Sample-first onboarding: swatch book, then trial roll, then production release.

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.
