What an inlay is
An RFID inlay is the working core of a smart label: an antenna with the chip attached, on a thin substrate. Whether it is "dry" or "wet" simply describes whether adhesive has been applied — and that decides how you convert it into a finished product.
Dry vs wet inlay
| Property | Dry inlay | Wet inlay |
|---|---|---|
| Adhesive | None | Pressure-sensitive adhesive |
| Use | Laminate / embed into product | Peel and stick directly |
| Typical buyer | Label converters, card makers | End users, packers |
| Cost | Lower (no adhesive) | Slightly higher |
| Format | Reel | Reel, ready to apply |
Choose a dry inlay when
You manufacture your own labels, cards or tickets and will laminate the inlay between layers, or embed it into a product. Dry inlays give converters maximum flexibility and the lowest cost.
Choose a wet inlay when
You want to apply tags directly to products, cartons or documents with no extra converting step. Wet inlays peel off the liner and stick down immediately, ideal for retail and logistics tagging.

Frequently asked questions
What is the difference between a dry and wet RFID inlay?
A dry inlay has no adhesive and is meant for laminating or embedding; a wet inlay has a pressure-sensitive adhesive so it can be peeled and stuck directly onto an item.
Which inlay do label printers use?
RFID label printers typically use white-faced wet inlays (printable RFID labels) so the label can be printed and encoded, then applied in one step.
Can inlays be pre-encoded?
Yes, both dry and wet inlays can be supplied blank or pre-encoded to your numbering scheme.
