HTL1 High Temperature RFID Label


  • High temperature applications
  • Barcode and alphanumeric information available
  • Economical high temp solution
  • Long read range (up to 30 feet)



An economical solution for high temperature applications, the HTL1 uses a proprietary design to survive heat. Most RFID labels are rated to survive at temperatures up to 150°F, but the HTL1 high temperature RFID label will survive temperatures up to 300°F for 30 minutes or more. These William Frick high-temperature RFID labels have been used for process tracking and paint line asset tracking.


A variety of sizes and inlays are available. The HTL1 comes pre-printed (alphanumeric or barcode information) or as thermal transfer blanks for on-demand printing and encoding.


High Temperature Resistant


The HTL1 label is made with a temperature-resistant film. In addition, the adhesive is specifically chosen for its performance in high temperature performance. These features ensure the HTL1 will perform superbly in high temperature environments.

HTL1 High Temperature RFID Label

Dimensions 4” x 2” custom sizes available
Available Colors White with black text. Custom colors available
Thickness 5 mil
Operating Temperature -40º F to 185º F (-40º C to 85º C)
Min Application Temperature 50º F (10º C)
Survival Temperature -40º F to 300º F (-51º C to 149º C) for 30 minutes or more



Test* Temperatures and Duration Results
Maximum Temperature Long-term at 10 hr: 300°F (149°C) No effect on tag. Tag remained the same in appearance and RFID performance/function. There was no sign of peeling, tearing or destruction. The tag read normal after the tests. *Test is not limiting.

Standard at 5 min: 340°F (171°C)

Short-term at 90 sec: 360°F (182°C)
Minimum Temperature -40°F (-40°C)
Temperature Cycling The tag was cycled to 360°F at equilibrium for five times. Between each cycle, it was air cooled to room temperature and read with an RFID reader.

Custom colors and sizes available. Polyimide film facestock offers excellent durability in high-temperature and miniaturized electronics applications.
