Labels & Tags: Production Process Guide

Overview #

Hang tags and swing tags sit at the intersection of brand identity and product information — a 60 × 90mm card stock tag is often the first physical touchpoint a consumer has with your brand before opening the packaging. Getting the production process right means controlling five distinct stages: substrate selection, printing, finishing, die-cutting, and assembly. Brands in apparel, cosmetics, food gifting, and home goods consistently brief us on tags that look premium at retail but survive warehouse handling, international shipping, and retail floor display without curling, ink cracking, or eyelet failure. The single most common brief mistake we see is specifying a heavy coated stock without accounting for the post-print finishing process — a 350 GSM coated board with soft-touch lamination behaves very differently on the die-cutter than the same board with UV spot varnish.

Substrate Selection and Structural Parameters #

The substrate decision drives every downstream process parameter. For standard hang tags, we work primarily within a 250–400 GSM range. Below 250 GSM, the tag lacks the rigidity required for eyelet punching — the hole tears rather than punches cleanly, and the tag folds under its own weight when hung on a garment rail. Above 400 GSM, we see feed issues on our sheet-fed offset presses and the die-cutting rule requires higher tonnage, which increases the risk of back-score cracking on coated stocks.

Our most specified substrates for hang tags:

For FSC chain-of-custody compliance — which roughly 40% of our EU and Australian brand partners now require — we source SBS and kraft boards certified under FSC-STD-40-004. We carry FSC CoC certificate number on file and can provide documentation for your own sustainability reporting.

Caliper tolerance on our incoming board stock is held to ±0.05mm against nominal. We measure every incoming reel or sheet batch with a Mitutoyo digital caliper gauge and reject any batch outside this tolerance before it reaches the press floor.

Printing Process Parameters and Ink Specification #

The majority of our hang tag volume runs on sheet-fed offset (Heidelberg XL 75 and Komori Lithrone S40 lines), with digital (HP Indigo 7K) used for short runs under 500 units or variable data requirements. Gravure and flexo are not used for hang tags — the substrate rigidity and short-run economics don’t support it.

On our sheet-fed offset lines, our standard register tolerance is ±0.15mm for hang tags. This is tighter than our folding carton standard (±0.2mm) because tag dimensions are small — a 0.2mm register error on a 60mm-wide tag is visually significant at the eyelet area and at fine-detail brand marks.

Ink specification for coated SBS: we run UV-cured offset inks at a cure energy of 120–160 mJ/cm² (measured with a UV Power Puck II radiometer). Under-cured ink on a coated surface is the primary cause of blocking in stacked tag sheets and smearing during lamination. We check cure completeness with a thumb-rub test at the delivery end of the press — any smear triggers a press stop and lamp intensity adjustment before the run continues.

For Pantone colour matching, we work to a Delta-E tolerance of ≤2.0 on coated stocks (ISO 12647-2 standard). On uncoated kraft, we advise brand partners to expect a Delta-E shift of 2.5–4.0 versus the coated proof — ink absorbs into the fibre and colours appear more muted. We always produce a physical press proof on the actual substrate before approving a kraft tag run.

Surface Finishing and Die-Cutting Controls #

Finishing is where hang tag production either elevates the brand or introduces defects that reach the consumer. The three most common finishing combinations we run are:

1. Matte lamination + UV spot varnish — 28–32 micron BOPP matte film, spot UV applied at 8–12 microns wet thickness
2. Soft-touch lamination — 28 micron velvet-feel BOPP, no spot UV (spot UV adhesion on soft-touch is unreliable without primer)
3. Hot foil stamping + emboss — foil applied at 90–110°C, 0.3–0.5 MPa pressure, emboss depth 0.3–0.8mm depending on board caliper

Die-cutting for hang tags uses steel-rule dies on our Bobst SP 102-E flatbed cutter. Cutting rule tolerance is ±0.1mm on finished tag dimensions. We run a first-article inspection on every die-cut job: 10 tags pulled from the first sheet, measured with digital calipers, and signed off before the full run proceeds.

Eyelet punching is done inline on our semi-automatic eyelet press. Standard eyelet diameter is 4mm (inner) for cotton cord and 5mm for ribbon. We specify a minimum 4mm of board material between the eyelet edge and the tag edge — below this, the board tears under load. For tags above 350 GSM, we reinforce the eyelet zone with a 25mm diameter adhesive patch on the reverse before punching.

Quality Control Checkpoints and AQL Standards #

We apply a three-stage QC process on all hang tag production:

• Stage 1 — Pre-press: Colour proof approval against Pantone reference, substrate caliper check, ink adhesion test (cross-hatch tape test per ASTM D3359)
• Stage 2 — Inline: Register check every 500 sheets, ink density measurement (target density ±0.05 on L*a*b* scale), lamination bond strength spot check
• Stage 3 — Outgoing: AQL 2.5 sampling inspection per ISO 2859-1 (ANSI/ASQ Z1.4 equivalent), covering dimensional accuracy, eyelet integrity, surface defects, and colour consistency

Our outgoing AQL 2.5 inspection means that for a shipment of 10,000 tags, we inspect a sample of 200 units with an acceptance number of 10 for major defects and 21 for minor defects. Any lot failing AQL is 100% inspected before release.

For brands supplying to EU retailers, we can provide REACH-compliant ink declarations — our UV offset inks are formulated without restricted substances under REACH Regulation (EC) No 1907/2006, and we hold supplier declarations for all ink systems in use.

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 (W × H in mm), substrate preference or brand sustainability requirements, finishing combination, eyelet position and cord/ribbon type, and your target retail price point. If you have an existing tag from a previous supplier, send us a physical sample — we can reverse-engineer the substrate GSM and finishing stack within one working day.

The most common brief mistake we see is brands specifying “premium feel” without defining whether that means soft-touch lamination, textured stock, or heavy board weight — these are three different production routes with different lead times and costs. We’ll always ask you to clarify before quoting.

Our typical process: digital colour proof in 3–5 working days, physical sample (including eyelet and cord assembly) in 10–14 working days, production lead time 18–25 working days after sample approval. MOQ for offset-printed hang tags is 1,000 units per design; digital print MOQ is 200 units.

Frequently Asked Questions #

Q1: What is the minimum board weight you recommend for hang tags with eyelet punching?
A: We specify a minimum of 250 GSM for eyelet punching — below this, the board tears at the punch point rather than cutting cleanly, and the tag lacks the rigidity to hang without folding. For tags with ribbon (heavier than cotton cord), we recommend 300 GSM minimum to handle the load at the eyelet.

Q2: What is your MOQ and lead time for a custom hang tag order?
A: Our MOQ for offset-printed hang tags is 1,000 units per design, with a production lead time of 18–25 working days after sample approval. For short runs under 500 units, we use our HP Indigo 7K digital line — MOQ drops to 200 units but unit cost is higher and foil stamping is not available on that line.

Q3: Can you supply FSC-certified hang tags for our EU sustainability reporting?
A: Yes — we source SBS and kraft board stocks certified under FSC-STD-40-004 and hold our own FSC chain-of-custody certificate. We can provide full documentation for your supplier audit file. Approximately 40% of our EU brand partners now specify FSC-certified substrate as a standard requirement.

Q4: Can you combine soft-touch lamination with hot foil stamping on the same tag?
A: We can, but the sequence matters. Foil is applied before lamination in our standard process — foil adhesion to soft-touch BOPP is unreliable without a primer coat, which adds cost and lead time. If you want both effects, we recommend foil first on the printed sheet, then soft-touch lamination over the non-foil areas. Foil temperature is held at 90–110°C to avoid delamination at the foil boundary.

Q5: What causes hang tags to curl after production, and how do you prevent it?
A: Curl is almost always a moisture imbalance issue — one side of the board absorbs ambient humidity faster than the other, typically when a heavy lamination is applied to one face only. We control this by conditioning board stock at 50–55% relative humidity for 24 hours before printing, and by specifying a minimum 28-micron lamination film on both faces when the design allows. Tags stored in sealed poly bags immediately after finishing show significantly lower curl rates in transit.
