§ Field Problem · Nº 07 High-Temperature

“I need a label that
survives the heat.”

The temperature ceiling is set by the substrate, not the ink. PVC vinyl tops out at 80 °C; PET takes 150 °C; polyimide handles 200+. The right material depends entirely on how hot it actually gets.

The Euphora scale

Levels,
measured not marketed.

Manufacturers love absolute claims. We made a scale because “high-temperature” means different things in different jobs. Pick the level your job actually requires.

Field Notes

Questions we
get most weeks.

Q. 01
Can I use vinyl on oven labels?
No. PVC vinyl softens above 80 °C. Use PET for any oven-adjacent application, polyimide for direct oven contact.
Q. 02
What about steam sterilisation (autoclave)?
Standard PET handles autoclave cycles up to 121 °C for 30 minutes. Specify steam-rated PET for repeated cycling.
Q. 03
Are there food-safe high-temperature materials?
PET carries FDA / EFSA food-contact approvals at high temperature. Polyimide is not typically food-contact rated.
Q. 04
What about labels for direct flame contact?
No commercial sticker substrate handles direct flame. For oven-cooking applications, use a printed metal tag, not a label.
