ISO18000-6C Gen2 UHF PET RFID Tag Wet Inlay

 

Understanding the ISO18000-6C Gen2 Standard

ISO/IEC 18000-6C, commonly called EPC Gen2, defines how passive UHF RFID tags communicate with readers.

Key characteristics of this standard include:

• Long read range (up to 10 meters or more, depending on environment)

• Anti-collision support for bulk reading

• High data transmission speed

• Global interoperability

• Low power consumption (passive, battery-free)

Because of this standardization, Gen2 UHF PET wet inlays can be deployed worldwide across logistics hubs, warehouses, factories, and retail stores with minimal compatibility issues.

Structure and Materials: Why PET Matters

PET Substrate Explained

The antenna of the wet inlay is mounted on PET (Polyethylene Terephthalate), a material chosen for its balance of performance and cost.

PET offers:

• Excellent dimensional stability

• Good heat resistance

• Flexibility for label conversion

• Consistent RF performance

• Compatibility with high-speed label production

While PET is not designed for extreme temperatures or harsh chemicals, it performs exceptionally well in standard commercial and industrial environments.

Typical Technical Specifications

Key Advantages of UHF PET RFID Tag Wet Inlays

1. Cost Efficiency at Scale

Wet inlays are designed for mass production. When deployed in millions of units, the cost per tag becomes extremely competitive, making them suitable for retail, logistics, and fast-moving consumer goods.

2. Long Read Distance

Compared with HF or NFC tags, UHF wet inlays provide much longer read ranges, enabling portal reading, conveyor scanning, and bulk inventory checks.

3. Easy Label Conversion

Thanks to the adhesive backing, wet inlays integrate seamlessly into:

• RFID smart labels

• Barcode + RFID hybrid labels

• Shipping labels

• Hang tags

No additional bonding process is required.

4. High Reading Speed and Anti-Collision

Gen2 protocol allows hundreds of tags to be read simultaneously, solving one of the biggest bottlenecks in manual scanning systems.

5. Global Compatibility

ISO18000-6C compliance ensures compatibility with:

• Fixed UHF RFID readers

• Handheld RFID scanners

• RFID gates and portals

• Automated warehouse systems

Industry Applications of ISO18000-6C UHF PET Wet Inlays

Logistics and Supply Chain Management

In logistics, visibility is everything. UHF PET RFID wet inlays enable:

• Pallet and carton tracking

• Automated receiving and shipping

• Real-time inventory updates

• Reduced manual scanning errors

Large distribution centers rely on these inlays to process thousands of items per hour.

Retail and Apparel

Retail is one of the fastest-growing markets for UHF RFID.

Applications include:

• Item-level tagging for apparel

• Smart fitting rooms

• Automated stock counts

• Loss prevention and anti-theft integration

• Omnichannel inventory synchronization

UHF wet inlays are thin, flexible, and cost-effective enough to be embedded into clothing labels without affecting user experience.

Manufacturing and Work-in-Progress Tracking

Manufacturers use UHF RFID wet inlays to track:

• Components and subassemblies

• Production batches

• Process flow status

• Quality control checkpoints

This creates a digital thread across the factory floor, reducing errors and improving throughput.

---

Warehouse and Asset Management

For warehouses managing tools, containers, or returnable assets, UHF PET wet inlays enable:

• Fast inventory audits

• Location-based tracking

• Reduced asset loss

• Improved utilization rates

Compared with barcodes, RFID does not require line-of-sight, saving time and labor.
