Laundry Tag

Laundry Tag

A RFID tag for textiles." data-category="Applications">laundry tag is a ruggedized RFID tag specifically engineered to survive repeated industrial washing, drying, pressing, and chemical treatment. These tags are typically encapsulated in silicone, epoxy, or thermoplastic housings that protect the tag IC and antenna from heat, moisture, mechanical stress, and harsh detergents.

Construction and Form Factors

Laundry tags use a UHF inlay -- commonly based on the Impinj Monza or NXP UCODE IC families -- sealed within a protective housing. Common form factors include button tags (sewn into garment seams), flat patch tags (heat-sealed onto fabric), and linen tags (thin, flexible strips embedded in hem folds). The encapsulation must withstand temperatures up to 180-200 degrees Celsius during industrial ironing and tunnel finishing.

Key specifications for laundry tags include IP68-rated water resistance, survival through 200+ industrial wash cycles (60-85 degrees Celsius), and chemical resistance to bleach, peracetic acid, and alkaline detergents. The antenna design must account for the proximity of fabric, which has minimal RF impact, and occasional contact with metal buttons or zippers that cause detuning.

Applications

The primary market for laundry tags is commercial and industrial textile rental services -- hotels, hospitals, restaurants, and workwear providers. These operations manage millions of textile items that cycle through commercial laundries multiple times per week. RFID enables automated piece counting at collection and delivery, wash cycle tracking, loss detection, and lifecycle management.

Healthcare linen management uses laundry tags to ensure proper sterilization and prevent cross-contamination. Each item's wash history is recorded, and items exceeding their maximum wash count are automatically flagged for replacement.

Integration with Enterprise Systems

Laundry RFID systems use portal readers at soiled linen collection points, clean linen sorting stations, and delivery loading docks. The middleware layer tracks each item's status (in service, in laundry, retired) and generates alerts for overdue items. EPCIS events record each processing step, building a complete lifecycle history per garment. This data feeds into billing systems (per-piece pricing), quality control (wash count tracking), and purchasing (replacement forecasting).
