PTFE Tape for Food Contact: Temperature & Time Limits You Must Follow
PTFE high-temperature tape used in food contact must respect strict temperature limits: ≤260°C for continuous use (no time limit), 260-300°C for up to 30 minutes only, and >300°C prohibited. The tape is for indirect contact only (tray liners, heat sealer covers), not direct food wrapping. Never operate without food load (dry heating). Replace if blistered, yellowed, or worn.
