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 initiating 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 the temperature and exposure, users can determine if the product is safe and effective or needs replacing.

Prevent Spoilage with Temperature Indicators

Understanding cold chain management and logistics is crucial with the increasing temperature sensitivity of products. Packaging indicators enable users to gain insights into cold chain logistics, identifying 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.
