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.

What about steam sterilisation (autoclave)?

Standard PET handles autoclave cycles up to 121 °C for 30 minutes. Specify steam-rated PET for repeated cycling.

Are there food-safe high-temperature materials?

PET carries FDA / EFSA food-contact approvals at high temperature. Polyimide is not typically food-contact rated.

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.

“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.
