SIVA – UNI™ GP 42 – 4” × 2” UHF RFID Paper Label

The SIVA UNI™ GP 42 is a compact 4” × 2” UHF RFID paper label designed for high-volume logistics, parcel shipping, carton labeling, and pallet tracking. Its smaller footprint makes it ideal for applications where space is limited but long-range RFID performance and fast scanning are still required.

Operating across global UHF RFID frequencies (865–928 MHz), the GP 42 delivers excellent read performance on cardboard and plastic, supporting efficient workflows in warehouses, distribution centers, e-commerce fulfillment, postal services, and 3PL operations. The printable white paper face stock enables high-quality thermal transfer printing of barcodes, shipping data, EPCs, serial numbers, and compliance markings, allowing seamless integration into existing shipping and WMS systems.

Engineered as a cost-effective RFID shipping label, the GP 42 is ideal for organizations scaling RFID adoption across case-level and parcel-level identification without increasing labeling complexity or cost.
