WarmMark

For Monitoring the Duration of Damaging Temperatures

WarmMark Time-Temperature Tags put you in control even after your product has been shipped. With WarmMark, your customers know at a glance if the product has been exposed to abusive temperatures during shipping or storage.

WarmMark also indicates if that exposure has continued for an extended period of time. WarmMark Time-Temperature Tags are a strategic, value-added plus for your product, providing a permanent record that assures your customers of consistent quality.

Real-world application examples.

• Pharmaceuticals and blood products
• Food Products
• Adhesives
• Photographic and film products

How WarmMark Works

WarmMark Time-Temperature tags are designed for accurate monitoring at the lowest possible cost. Its basic components are:

• A track strip of blotter paper running length of the tag.
• A blotter paper pad saturated with a red-dyed chemical specially formulated to melt at the tag's response temperature.
• A strip of barrier film separating the track strip and the saturated pad.

Its innovative construction makes WarmMark Tags the most accurate, cost-effective choice for your product monitoring.

To prepare the WarmMark Tag for use, store the tag for a minimum of 30 minutes at least 5°C below the response temperature. Then apply the WarmMark Tag by peeling the release liner off the back of the tag and adhering the pressure sensitive adhesive backing to a dry surface. Then, if the tag is exposed above its response temperature, the chemical in the pad melts and begins to migrate down the track strip and color in the circular windows at a controlled rate. When the temperature falls below the response temperature, migration of the chemical stops. Accuracy of the WarmMark Tag is guaranteed to be within 1° above or below the response temperature.
