WarmMark is a single-use temperature indicator that alerts users when unacceptable temperatures are reached. It is designed to prevent the distribution of spoiled goods by triggering a visual warning when there are breaches in the cold chain.
Temperature-sensitive products can spoil quickly if not kept at their optimal temperature, and the packaging indicator helps users identify and address breaches.
Accurate Monitoring of Temperature Exposure
To assess the duration of exposure, the WarmMark features three breach windows: brief, moderate, and prolonged. Users can determine the product’s condition by checking these windows and making informed decisions. When it reaches the selected temperature threshold, it turns red and begins a countdown. The three indicator dots change colour to represent brief, moderate, and prolonged exposure.
The duration of each exposure category varies depending on the temperature. For instance, “brief” exposure means 2 hours at 0°C/32°F but only 30 minutes at 25°C/77°F and above. Based on temperature and exposure, users can determine if the product is safe and maintained its integrity or needs to be replaced.
Prevent Spoilage with Temperature Indicators
Understanding cold chain management and logistics is crucial as products become increasingly temperature sensitive. Packaging indicators enable users to gain insights into cold chain logistics and identify packages that may have experienced thermal damage.
Activating the WarmMark is simple: fold up and pull out the indicator activation tab, remove the adhesive liner, and paste the indicator onto a clean, dry surface. It suits various applications, including floral, chocolate, food, raw and cooked meats, chemicals, tissue samples, and pharmaceuticals.
QR Version Available
WarmMark is also available in a QR-enabled version. Users can scan the QR code to record temperature excursion data along with time, location, and serial number, helping improve traceability and support product quality assurance throughout the supply chain.
