HID SlimFlex Seal Mini UHF RFID Tag | M781

Seal bags, bins, and containers with a single tag that gives you both RFID tracking and tamper evidence in one step. The HID SlimFlex Seal Mini UHF RFID Tag combines an Impinj M781 RAIN UHF chip with an integrated nylon cable tie, so every sealed container gets a unique electronic ID and a visual indicator that's immediately obvious if someone has cut or broken the seal. With 128-bit EPC and 512-bit user memory, there's room to encode item-level data directly on-tag, and the broadband 865–928 MHz frequency supports global deployments without swapping hardware.

The compact TPU tag body measures just 60 × 12 × 2 mm (2.4 × 0.5 × 0.08 in) and the integrated cable tie extends 200 mm (7.8 in), making it flexible enough to cinch around a wide variety of containers, pouches, and transport items. Reads reach up to 4 m (13.1 ft) in free air at 2W ERP, so handheld and portal-based inventory scans stay fast even across large shipments. The tag is IP68 waterproof, resistant to mineral oil, petroleum, salt mist, bleach, and UV exposure, and operates from -40° to +70° C (-40° to +158° F). Pull resistance exceeds 65 N, and the flexible TPU housing tolerates repeated bending down to a 150 mm radius without impacting performance.

The SlimFlex Seal Mini replaces separate seal and tracking steps with one tamper-evident RFID tag that attaches like a cable tie and reads up to 4 m  (13.1 ft) away. Its IP68-rated TPU body, 512-bit user memory, and global UHF frequency make it a compact, durable solution for securing and inventorying containers, returnable transport items, and safety equipment across storage and distribution workflows.
