SIVA – RE-LOAD PRO 4620 – Compact UHF RFID Label for RTI & Reusable Plastic Containers

The SIVA RE-LOAD PRO 4620 is a compact, high-durability UHF RFID label engineered for returnable transport items (RTIs) and reusable plastic containers used in closed-loop logistics and industrial supply chains. Its small application footprint makes it ideal for crates, totes, bins, and containers where space is limited but long-term RFID performance is essential.

Designed to withstand high-temperature chemical washing, moisture, and aggressive industrial handling, the RE-LOAD PRO 4620 delivers reliable identification across repeated reuse cycles. It performs consistently on non-metallic surfaces, including low-surface-energy plastics, making it well suited for food & beverage logistics, retail pooling systems, manufacturing containers, and automated warehouses.

With a printable white PET face stock and high-performance acrylic adhesive, the label integrates seamlessly into existing RFID printing and encoding workflows, supporting scalable asset traceability and operational efficiency.
