The WarmMark is a single-use, time-temperature packaging indicator with a visual warning to be set to an optimal temperature that alerts users of extreme temperature conditions. As temperature-sensitive products spoil quickly if not kept under optimal temperature, the WarmMark temperature packaging indicator offers visual warnings to users when cold chain breaches have occurred, preventing users from accidentally distributing spoilt goods unfit for consumption. The duration of exposure is checked with the conditions: brief, moderate, and prolonged.


Fold up and pull out the indicator activation tab, remove the adhesive liner and paste the indicator to a clean, dry surface. The WarmMark is ideal in applications such as:

  • Chemicals
  • Chocolate
  • Floral
  • Food
