RFID Wet Inlay Overview
RFID wet inlays are adhesive-backed RFID transponders designed as the core layer for RFID labels, NFC stickers and smart packaging products. Each inlay consists of an RFID chip, etched antenna, flexible substrate, pressure-sensitive adhesive and release liner. Compared with dry inlays, wet inlays are easier to convert into finished labels because the adhesive layer and liner are already included.
CedaGlo RFID wet inlays can be supplied in roll or sheet format for printing, die-cutting, lamination, encoding and label converting. Depending on the application, customers can choose UHF RFID wet inlays for logistics and retail item-level identification, HF/NFC wet inlays for smartphone interaction and product authentication, or dual-frequency inlays for projects that require both UHF long-range reading and NFC mobile engagement.
They are widely used by label converters, packaging suppliers, RFID solution integrators, brand owners and OEM customers who need a reliable inlay base for finished RFID labels, product stickers, authentication labels and smart packaging solutions.

Why Buyers Choose RFID Wet Inlays
RFID wet inlays are mainly purchased by label converters, smart packaging manufacturers, RFID label suppliers and system integrators. These buyers usually need a converter-friendly inlay format that can be printed, laminated, die-cut, encoded and converted into finished RFID or NFC labels.
For UHF applications, buyers focus on read performance, antenna size, chip platform, roll format, encoding compatibility and stable production supply. For HF/NFC applications, they care more about smartphone compatibility, product authentication, user interaction, memory capacity and label appearance. For OEM converting, buyers also need consistent pitch, roll direction, chip-up or chip-down layout, release liner quality and custom antenna options.
CedaGlo RFID wet inlays are designed for these project requirements, offering flexible frequency options, multiple chip selections, custom antenna support and roll or sheet supply for downstream label conversion.

Are NFC wet inlays compatible with smartphones?
NFC wet inlays can be compatible with NFC-enabled smartphones when NFC-compatible chips such as NTAG series or other supported HF chips are used. Final compatibility depends on chip type, phone model, encoding format and label design.
Can you customize antenna size and inlay layout?
Yes. Antenna size, chip position, inlay pitch, roll direction, chip-up or chip-down layout and wet inlay format can be customized based on the final label or packaging design.
Can you encode data before shipment?
Yes. EPC, UID, URL, serial number or project-based data encoding can be supported depending on chip type and customer requirements. Encoding details should be confirmed before production.
What applications are RFID wet inlays suitable for?
RFID wet inlays are suitable for label converting, smart packaging, retail tagging, logistics identification, asset labeling, library or document management, embedded integration and brand protection.
