The problem

Returnable Transit Packaging (RTP) is widely used in electronics supply chains to reduce packaging waste and logistics cost. These containers are repeatedly handled, stacked, and transported across different environments.

Standard RTP materials—typically plastics or composites—are electrically insulating and can accumulate static charge during movement and vibration, creating ESD risk during loading, unloading, and unpacking.

The substrate

Injection-moulded plastic RTP crates, bins, pallets, and lids designed for repeated logistics cycles and mechanical durability.

Why replacement was not viable

• High capital investment in existing RTP fleets
• Limited availability of ESD-specific RTP formats
• Increased cost and weight of conductive plastic alternatives
• Sustainability targets favouring reuse

The ProShieldESD solution

ProShieldESD was applied as a thin, uniform coating to the internal and external surfaces of RTP containers. The two-part coating bonds strongly to plastic substrates and provides controlled, humidity-independent ESD behaviour.

The treated RTP remains compatible with automated handling, stacking, and cleaning processes.

Performance outcome

• Stable surface resistance across multiple logistics cycles
• Uniform charge dissipation during transport and handling
• No impact on mechanical strength or stackability
• Durable performance under repeated reuse

Standards alignment

The converted RTP supports ESD control programs aligned with IEC 61340 and ANSI/ESD S20.20 requirements when integrated into controlled logistics and handling systems.

Key benefits

• Protects electronics during repeated transport cycles
• Extends usable life of RTP fleets
• Reduces cost compared to conductive plastic RTP
• Supports circular and sustainable logistics models
