The ColdMark is a temperature packaging label designed for single use. It serves as a reliable indicator of temperature deviations below a certain threshold. When products are exposed to low temperatures, the label transforms from clear to violet, alerting shippers to the issue.

Single-Use Temperature Packaging Label

The activation period of the packaging indicator is approximately 30 minutes. It changes colour from clear to violet when the temperature exceeds a predetermined threshold. To ensure effective monitoring, the ColdMark should be positioned in a visible location for the shipment recipient.

It can be placed directly onto the product or inside the packaging. For optimal performance of these indicators, store them at a temperature at least 5°C higher than the activation temperature, with a maximum storage temperature of 43°C.
