Direct answer

What are RFID wet inlays?

RFID wet inlays are UHF transponder inlays supplied with a pressure-sensitive adhesive layer and a release liner. The word "wet" refers only to the adhesive: peel the liner off and the inlay bonds to a surface as it is, with no lamination step.

A dry inlay is the same chip-and-antenna construction on a PET carrier, without adhesive and without a liner. It is sold to converters who laminate their own face stock and adhesive before the inlay can be applied.

Where this sits

Three stages between a chip and a label

The same transponder is sold at three levels of finishing. Buyers lose money by ordering one level and then paying someone else to reach the next.

Stage 1

Dry inlay

Chip, antenna and PET carrier only. No adhesive, no liner, no face stock.

You add adhesive and face stock yourself

This page

Stage 2

Wet inlay

Stage 1 plus pressure-sensitive adhesive and a release liner. Ready to apply the moment it is peeled.

Either apply direct, or move to stage 3

Stage 3

Finished label

Stage 2 plus a printable face stock — coated paper, PET or PP. Carries a barcode, text and the inlay on one face.

Print and apply with a standard label printer

The usual question

Wet inlay or dry inlay?

Five things actually change the answer — and cost is only one of them.

Decision factor	Wet inlay	Dry inlay
Structure	Inlay + pressure-sensitive adhesive + release liner	Inlay only, on a PET carrier
Integration	Peel and apply by hand or by applicator. No laminating line needed.	Requires a converting or laminating process before use
Labour	Low — one step at the point of application	High — an extra production stage to plan and staff
Cost structure	Higher unit price (adhesive and liner included), lower labour cost	Lower unit price, higher labour and tooling cost
Best fit	Fast rollouts, large tagging volumes, finished labels, contractors who apply on site	Own converting line, embedding inside a material, very high volumes
Environment	Stable on damp or fluctuating surfaces once the adhesive grade is matched	Depends entirely on the face stock and adhesive added later

Where they are used

Three ways wet inlays get deployed

Applied direct

Cartons and packaging

Peeled and pressed onto a carton face at packing. No printer, no applicator, no converting step — which is what makes a wet inlay useful for a rollout that has to start this week.

Converted

Conveyor and gate reads

Converted into a printed label with a barcode on the same face, then read by a fixed antenna as cartons pass. Several cartons can be read in one pass, with no line of sight required.

Item level

Apparel and retail

Small inlays on folded or hanging garments, where the tag has to sit flat against fabric and stay readable through a full stock count.

Working with us

Three things we do before the container ships

01

Samples against your reader

Free samples cut to the inlay you are specifying, so you can measure them on your own reader and surface before committing to a volume.

02

Encoding and verification

EPC written to your data list, locked where required, and verified before packing. Send the scheme — SGTIN-96 or your own — with the order.

03

Inlay or finished label

We can ship the wet inlay alone or convert it into a printed label in the same order, so you are not moving material between two suppliers.

Technical parameters

Full specification

Construction and protocol are fixed for the wet inlay format. Inlay size, chip and read performance are set by the specific inlay you order, and are confirmed on the datasheet before production.

Construction

Build-up	Inlay (PET carrier + etched aluminium antenna + chip) + pressure-sensitive adhesive + release liner
Liner	Glassine release liner, whiteGrammage confirmed per order
Adhesive	Permanent acrylic as standard; removable and freezer grade on request
Supply form	Roll, multi-upCore diameter and repeat agreed at order

Radio and protocol

Protocol	EPCglobal Class 1 Gen 2 / ISO IEC 18000-6C (ISO IEC 18000-63)
Frequency	860–960 MHz — operating band fixed for the destination market
Type	Passive, read / write
Read range	Set by the inlay designMeasured with your reader and surface, not assumed

Chip and services

Chip	Per order — confirmed on the datasheetSend the memory and sensitivity you need and we match the silicon
Encoding	EPC write, lock and verify available
Conversion	Can be supplied as finished labels with paper, PET or PP face stock
Samples	Free samples on request

Questions buyers ask

Frequently asked questions

What does "wet" actually mean?

Only that pressure-sensitive adhesive and a release liner are already applied. The chip and antenna are identical to the dry version of the same inlay — nothing about the RF design changes.

Can I print on a wet inlay?

Not directly. A wet inlay has no printable face stock, so there is nothing for a printer to lay ink onto. Convert it into a label first, or order the finished label from us.

Which protocol and frequency?

EPCglobal Class 1 Gen 2 / ISO IEC 18000-6C (now numbered ISO IEC 18000-63), in the UHF band 860–960 MHz. The operating slice is fixed for the market where the tags will be read.

Does the adhesive reduce read range?

No. The adhesive and liner are peeled away, so neither sits in the RF path. What can cost you range is the face stock added during conversion — re-measure after lamination rather than reusing the bare inlay figure.

Will it stick to metal or to liquid containers?

A standard wet inlay will not — metal and liquid detune the antenna. Those surfaces need an on-metal or thick-substrate inlay. State the surface at the quotation stage rather than after delivery.

Can it survive cold storage?

Yes, with a freezer-grade adhesive. Tell us the service temperature and the dwell time on the surface, and we match the adhesive grade rather than shipping the standard acrylic.

Do you supply in roll form?

Yes. Rolls with the core size and multi-up layout agreed at order. Sheet supply is possible on request for pilot runs.

Can you encode the EPC before shipping?

Yes. Send the data list and the EPC scheme (SGTIN-96 or your own), and we encode, lock where required, and verify before packing.
