RFID Dry Inlay vs Wet Inlay
RFID dry inlay and RFID wet inlay are two common semi-finished forms used in RFID label production. Both include an RFID chip and antenna, but their structure and use are different.
Dry Inlay
An RFID dry inlay usually includes the chip, antenna, and substrate. It does not include an adhesive backing or release liner. Because of this, dry inlay is mainly used for further converting, such as RFID cards, tickets, labels, hang tags, or embedded RFID products.

Dry inlay is a better choice when the RFID part needs to be embedded into another product or converted into a special label structure. It gives label manufacturers more flexibility in adhesive selection, face material, printing, and final label design.
Wet Inlay
An RFID wet inlay is based on a dry inlay, but it also includes an adhesive backing and release liner. This makes it easier to apply to products, packaging, books, files, or assets. It can also be converted into finished RFID labels or smart labels.

For high-frequency blank library tags, wet inlay is usually more practical. It already has adhesive and release liner, so it can be made into self-adhesive labels for books, archive files, and library materials.
