WarmMark Indicators are widely used in pharmaceutical, chemical, and meal delivery industries to alert the users about the exposure of the products to unacceptable temperature conditions. Frozen food products can also be stored by using WarmMark temperature indicator. The response temperatures and run-out times vary with each model. Color movement with the help of indicator records the exposure duration, and if the temperature falls below the threshold, the color stops moving. Using WarmMark indicators, one can have a positive effect on the bottom line as it indicates the long term exposure of the product’s longevity and expiry dates. This means that the indicator turns into a bright red color.
