Product Overview
The T4221FL is a high-performance UHF RFID flag tag specifically designed for item-level tracking in retail and healthcare applications. Its unique "flag" design features an adhesive base for secure attachment to products, while the non-adhesive flag portion extends outward to ensure optimal RF performance and visibility. Built with Impinj's Monza R6-P chip and an etched aluminum antenna on a flexible PET substrate, this tag delivers reliable, long-range identification even in challenging environments.

Appearance and Structural Diagram
RFID Tag Layer Structure:
Face Stock (PET):Top printable layer of the tag to provide printable surface and environmental protection
Bonding Adhesive: Permanent adhesive for inlay attachment, to secures inlay to face stock permanently
Inlay → Inlay (Industry term - retain original): RFID chip + antenna embedded in substrate,
which contains the RFID IC and antenna (critical functional component)
Release Adhesive: Temporary adhesive for liner backing, which allows temporary attachment to liner
Release Liner (Siliconized Paper): Protective backing paper peeled during application, to enable die-cutting and protects adhesive until use
