Polyonics polyimide  and aluminum bar code label materials include high opacity, white topcoats specifically designed to maintain high contrast and readable bar codes through the extreme temperatures and harsh environments typical of metal processing.  They also include aggressive PSAs designed to remain firmly affixed to the metals throughout these same high temperature processes and can be applied up to 300°C.

The Polyonics XF-519 is a 2mil polyimide bar code label material with a matte white top coat, operational temperature of 200-225°C and short term temperature of 325°C. The XF-803 and XF-808 are 2 mil aluminum bar code label materials with non-yellowing silicone printable top coats. The XF-803 has an operating temperature of 400-500°C and short term temperature of 600°C. The XF-808 operates at 200-300°C with short term temperature of 350°C.
