Overview #
Garment hang tags and labels sit at the intersection of brand identity and supply chain function — they carry barcodes, care instructions, pricing, and brand story all on a substrate that may be 60mm × 90mm or smaller. For fashion, footwear, and accessories brands sourcing OEM production from China, the production process behind a hang tag is more technically demanding than it looks: substrate selection, print registration, die-cutting tolerance, and finishing adhesion all interact, and a failure in any one step creates tags that delaminate in transit, barcodes that fail retail scanners, or foil that lifts after 30 days in a humid warehouse. This guide walks through our production process step by step — from substrate specification through final QC — so brand partners understand exactly what we control and why.

Substrate Selection and Preparation #
The substrate decision drives every downstream process parameter. For hang tags, we work with three primary substrate families: coated duplex board, kraft board, and specialty textured stocks. Our standard coated duplex for mid-range fashion hang tags runs at 350 gsm, which gives a finished caliper of approximately 0.45–0.50mm — stiff enough to hold a metal eyelet without tearing, light enough to avoid drooping on fine knitwear. For premium footwear and accessories brands requesting a heavier hand feel, we move to 400 gsm or laminated constructions up to 600 gsm.
Kraft board is increasingly specified for sustainable fashion brands. We source FSC-certified kraft at 300–350 gsm; under FSC Chain of Custody (FSC-STD-40-004), we maintain full traceability documentation from pulp source to finished tag, which we provide as part of the compliance pack on request.
Before any sheet enters the press, we condition stock for a minimum of 24 hours at 23°C ± 2°C and 50% ± 5% relative humidity — aligned with ISO 187 paper conditioning requirements. Skipping this step on uncoated kraft causes moisture-driven curl that throws register on our sheet-fed offset presses by up to 0.4mm, which is outside our ±0.2mm tolerance for fine-detail brand artwork.
| Substrate Type | Typical GSM Range | Best Application | Key Limitation |
|---|---|---|---|
| Coated Duplex Board | 300–400 gsm | Mid-to-premium fashion tags, full-colour print | Less sustainable positioning |
| FSC Kraft Board | 280–350 gsm | Sustainable/natural brand positioning | Requires longer ink dry time |
| Textured Specialty Stock | 250–350 gsm | Luxury accessories, tactile brand experience | Higher cost, limited foil adhesion zones |
| Laminated Duplex | 400–600 gsm | Heavy footwear tags, metal eyelet applications | Longer lead time for lamination step |
Print Process Parameters and Inline QC #
The majority of our hang tag volume runs on sheet-fed offset (Heidelberg CX 102 platform), with short-run and variable-data jobs handled on HP Indigo digital. For offset, we target a dot gain of 12–15% at 175 lpi screen ruling on coated stock — exceeding 18% dot gain produces muddy shadow tones that compromise photographic brand imagery. We calibrate to G7 Master Colorspace standard, which means our press proofs are within ΔE ≤ 2.0 of the approved digital proof under D50 illuminant.
Register tolerance on our sheet-fed offset line is ±0.2mm. For hang tags with tight die-cut shapes — scalloped edges, custom silhouettes — we require a minimum 3mm bleed and 2mm safe zone inside the die-cut line. Tags with foil stamping or embossing require an additional 1.5mm clearance between the foil zone and the die-cut edge to prevent foil cracking at the cut.
Inline camera inspection runs on 100% of sheets. Our system flags:
– Register deviation > 0.25mm (auto-reject)
– Ink density variation > ΔE 3.0 from target (operator alert)
– Barcode quiet zone violations (auto-reject — critical for retail scan compliance)
For barcode-bearing tags, we verify against GS1 General Specifications. Minimum barcode magnification is 80% of nominal size; we recommend 100% for EAN-13 and UPC-A codes on tags smaller than 60mm wide. Every production batch includes a barcode verification report graded to ISO/IEC 15416 — we target Grade B or above as our minimum release standard, and Grade A for premium retail clients.
Finishing Operations: Foil, Emboss, and Coating #
Finishing is where hang tag production either elevates a brand or creates field failures. We run hot foil stamping at 80–120°C die temperature (adjusted by foil type and substrate), with dwell time of 0.08–0.12 seconds. Metallic foils on coated duplex require the lower end of this range; pigment foils on uncoated kraft need 100–115°C to achieve full transfer without substrate scorching.
Aqueous coating is our default protective finish — applied at 4–6 gsm wet weight, it provides adequate scuff resistance for most fashion hang tags without affecting recyclability. For tags requiring a premium soft-touch feel, we apply water-based soft-touch coating at 6–8 gsm; this finish increases the coefficient of friction on the tag surface, which helps tags stay positioned on garments during retail display. UV gloss spot coating is available for selective brand logo highlighting; our UV cure energy is 120–160 mJ/cm² depending on coating thickness.
One finishing combination we advise against: full-surface soft-touch coating combined with hot foil stamping in the same zone. The soft-touch coating’s micro-texture reduces foil adhesion by approximately 30–40% in our testing, leading to foil lift within 60–90 days under normal retail humidity conditions. The correct sequence is foil stamp first on uncoated or aqueous-coated substrate, then apply soft-touch coating with a 2mm exclusion zone around all foil areas.
Die-Cutting, Eyelet Setting, and Assembly #
Die-cutting tolerance on our flatbed die-cutting presses is ±0.3mm on standard shapes, tightening to ±0.2mm for precision silhouette tags when we use steel-rule dies with 0.71mm rule height. We inspect die-cut stacks at AQL 2.5 (per ANSI/ASQ Z1.4) — for a batch of 5,000 tags, this means inspecting a sample of 200 units with an acceptance number of 10 for minor defects and 0 for critical defects (barcode damage, eyelet misplacement, delamination).
Metal eyelets are set at 2.5mm or 4mm internal diameter depending on the cord or ribbon specified. Eyelet pull-out strength must exceed 15N — we test 5 samples per batch on a tensile tester per ASTM D1683 adapted methodology. Tags failing below 12N are rejected outright; those between 12–15N trigger a full batch hold and root-cause review.
String and ribbon attachment is the final assembly step. Polypropylene cord is standard; cotton twine and satin ribbon are available for premium applications. Cord loop length is typically 100–120mm finished, with a tolerance of ±5mm.
Specification Notes for Brand Partners #
When you brief us on a hang tag project, the most useful information you can provide upfront is: finished tag dimensions, substrate preference (or brand sustainability positioning), print colour count and any Pantone references, finishing requirements (foil, emboss, coating type), eyelet size and cord/ribbon specification, and whether the tag carries a barcode or QR code. If you have a retail compliance requirement — for example, GS1 barcode grading for a specific retailer — tell us at brief stage, not after press approval.
The most common brief gap we see is brands specifying “gold foil” without indicating whether they need a warm gold, cool gold, or rose gold — these are different foil stocks with different temperature profiles, and switching after press approval adds 3–5 working days. We keep a foil sample book and will send physical swatches before you commit.
Our typical process: digital colour proof in 3–5 working days, physical sample (including foil and finishing) in 10–15 working days, production lead time 18–25 working days after sample approval for quantities up to 50,000 units. MOQ is 500 units for standard shapes; custom die shapes require a minimum of 2,000 units to amortise tooling cost.
Frequently Asked Questions #
Q1: What board weight do you recommend for hang tags that need to carry a metal eyelet without tearing?
A: We specify a minimum of 350 gsm coated duplex for eyelet-bearing tags — below this weight, the eyelet pull-out strength frequently falls below our 15N minimum threshold, especially on tags with eyelets placed within 8mm of the tag edge. For heavier footwear tags, we move to 400 gsm or a laminated construction.
Q2: What is your MOQ and lead time for custom-shaped hang tags?
A: Our MOQ for custom die-cut shapes is 2,000 units to cover steel-rule die tooling. Standard production lead time after sample approval is 18–25 working days for quantities up to 50,000 units. Rush production at 12–15 working days is available for flat-print jobs without foil or emboss.
Q3: Can you provide barcode verification documentation for retail compliance?
A: Yes — every production batch that includes a barcode receives a verification report graded to ISO/IEC 15416. We target Grade B as our minimum release standard and Grade A for clients supplying major retail chains. If your retailer has a specific GS1 compliance requirement, share it at brief stage and we will confirm our process meets it before sampling.
Q4: Can you combine hot foil stamping with soft-touch coating on the same tag?
A: Yes, but the sequence and zone management matter. We apply foil first on uncoated or aqueous-coated substrate, then apply soft-touch coating with a 2mm exclusion zone around all foil areas. Full-surface soft-touch coating applied before foiling reduces foil adhesion by approximately 30–40% and leads to field failures — we will flag this if we see it in your brief.
Q5: What causes barcode scan failures on finished hang tags, and how do you prevent them?
A: The most common cause is quiet zone compression — when the die-cut line encroaches within 2mm of the barcode boundary, retail scanners fail to read the code reliably. We enforce a minimum 3mm quiet zone on all barcode layouts and run 100% inline camera inspection to flag violations before any sheet is cut. Barcode magnification below 80% of nominal size is a secondary cause; we recommend 100% magnification for tags under 60mm wide.
