Wholesale RFID Wet Inlay, Dry Inlay and Label Tag

Wholesale RFID Wet Inlays, Dry Inlays and Label Tags

Wallis supplies RFID wet inlays, dry inlays and converted label tags for high-volume smart-card, retail, logistics, packaging, library, event, asset-tracking and product-identification projects. Available technologies include 13.56MHz HF/NFC and 860–960MHz UHF RAIN RFID.

Wet inlays include pressure-sensitive adhesive and a release liner for label converting or compatible direct application. Dry inlays contain the chip-and-antenna assembly on a carrier without the final adhesive construction and are intended for further converting, embedding, lamination or integration into another product.

Buyers can customize the chip, protocol, antenna dimensions, inlay dimensions, adhesive, roll or sheet format, encoding, bad-tag marking, winding direction and packaging. Final RF performance must be validated on the actual application material and reader system.

Technical Specifications

The page-level frequency options include 869–915MHz UHF, 13.56MHz ISO/IEC 14443 and 13.56MHz ISO/IEC 15693. The exact chip, regional UHF band, antenna and finished construction should be confirmed before quotation.

Wet Inlay vs. Dry Inlay vs. Finished RFID Label

Select a Wet Inlay for Label Converting

Wet inlays are suitable when the buyer needs a self-adhesive RFID component for combination with a paper or synthetic face stock, printing, die cutting and final roll conversion.

Select a Dry Inlay for Embedding

Dry inlays are suitable when the RFID component will be laminated into a card, embedded into a molded item, encapsulated inside a wristband or integrated into another construction without a standard label adhesive.

Select a Finished Label for Direct End Use

A converted label is preferred when the customer requires a ready-to-print or preprinted product with the final face material, adhesive, die cut, encoding and roll specification already completed.

HF/NFC and UHF RFID Technology Selection

Frequency Does Not Define the Complete Product

Inlays operating at the same frequency may use different protocols, chip commands, memory structures and security functions. Supply the required reader, chip or protocol rather than selecting only by frequency.

Read Range Must Be Tested in the Final Construction

HF inlays may read within a few centimeters, while suitable UHF inlays may reach several meters. Final performance depends on the chip, antenna, reader power, regional band, tagged material, orientation and integration.

UHF Products Require Regional Band Planning

The antenna should be selected for the intended destination and reader environment. A product optimized for one UHF region may not provide the same performance in another.

Chip, Memory and Encoding Options

NTAG213, NTAG215 and NTAG216

These NFC Forum Type 2 chips are commonly selected for URLs, digital profiles, product information and consumer interaction. They provide different user-memory capacities, so the encoded NDEF content should be confirmed before chip selection.

MIFARE and DESFire Options

MIFARE Classic, Ultralight or DESFire products may be required for compatible access, membership, transport, event or secure smart-card systems. The reader, application, keys and software must match the exact chip family.

ICODE and ISO/IEC 15693 Options

ICODE inlays can support compatible library, asset and vicinity-card applications. They should not be assumed to work with every ISO/IEC 14443 reader.

UCODE, Impinj and Alien UHF Options

UHF chip selection should consider EPC memory, TID requirements, optional user memory, sensitivity, access or kill passwords and compatibility with the reader and software platform.

UID, TID and EPC Are Different Data Fields

HF/NFC products may expose a chip UID, while UHF products normally contain a factory TID and programmable EPC memory. Specify which identifier must be read, encoded, printed or matched to the customer database.

Encoding, Passwords and Locking

Services can include NDEF URL writing, EPC encoding, serial data, passwords and chip-specific locking. Permanent locks should be applied only after final data verification because they may not be reversible.

RFID Wet Inlays for Labels and Stickers

Pressure-Sensitive Adhesive Construction

Wet inlays include adhesive and a release liner, making them suitable for further label conversion. The adhesive must be matched to paperboard, glass, plastic, textile, painted surfaces or other application materials.

Printable Label Conversion

A paper, PET, PP or other face material can be laminated above the inlay to create a printable label for flexographic, digital, thermal-transfer, direct-thermal or UV printing.

Roll Format for Automated Processing

Wet inlays are commonly delivered on rolls for converting, encoding, printing or automatic application. Core size, web width, pitch and winding direction should match the downstream equipment.

Application Surface Testing

Adhesive strength and RF performance should be evaluated on the actual product. Metal, liquid, carbon-filled plastic, dense stacking and curved surfaces can change inlay performance.

RFID Dry Inlays for Cards and Product Embedding

Smart Card Lamination

Dry inlays can be integrated into PVC, PET or polycarbonate smart-card structures when antenna dimensions, chip position, total thickness and lamination temperature are compatible with the card design.

Wristbands, Tickets and Molded Products

Dry inlays can be encapsulated or laminated into wristbands, key fobs, tickets, badges and molded products using a construction that protects the chip and maintains antenna tuning.

Integration Can Change RF Performance

Cover layers, adhesives, plastics, printing inks, metal components and product contents may detune the antenna. Test the completed product rather than relying only on the free-air inlay result.

Roll or Sheet Supply

Dry inlays can be discussed in roll or sheet form according to the lamination, cutting, punching or product-assembly process.

Roll, Sheet and Converting Requirements

Antenna Size and Inlay Size

Antenna dimensions determine RF characteristics, while inlay or die-cut dimensions determine the carrier area required by the converting or embedding process. Both should appear on the approved drawing.

Core Size and Roll Diameter

Specify the core inner diameter, maximum roll outer diameter, web width and number of inlays per roll so the material fits the customer’s machine.

Pitch, Gap and Winding Direction

Pitch, web direction, chip orientation, cross-web position and inside- or outside-winding must match the converting, encoding or application process.

Sheet Layout for Card Lamination

Dry inlay sheets require an approved matrix showing antenna position, chip orientation, sheet dimensions, registration marks and compatibility with the final card punching layout.

Splice and Defective-Inlay Rules

Define whether defective inlays are removed, marked or retained and establish the maximum number of splices per roll. Automated production lines may require strict roll-continuity controls.

Applications of Wet and Dry RFID Inlays

Retail and Apparel Inventory

UHF wet inlays and converted labels can support item-level identification, stock counting, receiving, replenishment and supply-chain visibility when used with suitable readers and software.

Logistics and Warehouse Labels

RFID labels can identify cartons, totes, parcels, reusable containers and warehouse assets. The antenna and placement should be qualified on the actual package and contents.

NFC Product Interaction and Authentication

NFC wet inlays can be converted into stickers that connect compatible smartphones to product information, warranties, instructions, promotions or authentication services.

PVC, PET and PC Smart Cards

HF dry inlays can be laminated into access, membership, campus, hotel or transport cards when the chip, antenna and card structure match the intended reader system.

Libraries and Archive Management

ISO/IEC 15693 HF labels can support compatible library, document and archive workflows according to reader, data-format and placement requirements.

Events, Tickets and Wristbands

Inlays can be integrated into tickets, badges and wristbands for identification, access and engagement. Chip memory, security and read cycles should be selected for the event platform.

Industrial Asset Identification

RFID can support tools, equipment and fixed assets, but harsh environments, metal surfaces, chemicals and high temperature may require a specialized finished tag rather than a standard inlay.

Sample Testing and Quality Control

Electrical and Visual Inspection

The source page states that inlays undergo full electrical and visual inspection. The order specification should define the test method, acceptance standard, defective-inlay handling and inspection records required by the buyer.

RF Performance Testing

Test the inlay with the intended reader, power, antenna, tagged item, orientation and environment. Free-air read distance does not guarantee identical performance after label conversion or card lamination.

Adhesive and Converting Test

Wet inlay samples should be tested for release, tack, peel, die cutting, matrix stripping, roll feeding and compatibility with the face material and application surface.

Lamination and Embedding Test

Dry inlays should be tested through the complete lamination or molding process for chip survival, antenna connection, registration, flatness and post-process reading performance.

Encoding and Data Verification

Encoded UID, TID, EPC, NDEF, passwords and customer data should be read back and compared with the approved data file. Printed variable information should remain matched to electronic records.

Roll and Sheet Inspection

Verify count, pitch, web alignment, winding direction, core, splices, bad-tag marking, sheet layout and protective packaging before shipment.

Frequently Asked Questions

What is the difference between a wet inlay and a dry inlay?

A wet inlay includes pressure-sensitive adhesive and a release liner. A dry inlay is supplied without the final self-adhesive label construction and is intended for embedding, lamination or further conversion.

Is a wet inlay the same as a finished RFID label?

Not necessarily. A finished label normally adds a printable face material, application-specific adhesive, final die cut, printing and roll specification above the RFID inlay.

Can dry inlays be laminated into PVC, PET or PC cards?

Yes, when the antenna, carrier, chip position, lamination temperature, total thickness and card layout are designed for the selected inlay. A sample lamination test is recommended.

Do you supply both HF/NFC and UHF inlays?
