## Description
A European uniform-rental operator deployed Proud Tek PPS-housed UHF RFID laundry tags across 1.8 million garments in three rental pools (workwear,...

## FAQ
- Q: Can these tags survive ozone treatment?
  A: Yes. The PPS housing is chemically inert to ozone at the concentrations used in commercial laundry (<5 ppm). The customer's healthcare-uniform pool runs ozone disinfection on every cycle and survival data is indistinguishable between the workwear pool (no ozone) and healthcare pool (ozone every cycle) over 250+ cycles.
- Q: What read-rate degradation should we expect on heavily-wrinkled garments?
  A: Within 1 percentage point at the portal. The PPS tag is rigid and small (26 × 11 mm) so wrinkling around the tag is minimal even on bunched-up garments in a sorting bin. The dominant read-rate impact is metal interference (steel buttons, zip pulls). The customer's portal antennas are positioned to read the garment label side, which carries the tag, avoiding the metal-heavy seam side.
- Q: Is the PPS housing food-safe for kitchen wear?
  A: PPS itself is FDA-compliant for indirect food contact (21 CFR 177.2415) and the customer's kitchen-uniform pool has run on this tag for 18 months with no compliance findings. The tag is heat-sealed onto the inner garment label, not in food-contact surfaces.
- Q: How is end-of-life tag recovery handled?
  A: When a garment is retired, the PPS tag is mechanically cut from the garment label and recycled as a separate plastic waste stream. The chip itself is not recoverable in a useful form (it would need re-bonding to a new antenna), so the tag is treated as recyclable plastic. The customer is currently piloting a chip-reuse programme with Proud Tek where retired tags are returned for chip salvage and re-bonding to new antennas at 40% of new-tag cost.
