freeze check™
Our indicators are ideal for monitoring products that run the risk of damage when exposed to temperatures below freezing during transit and storage. Freeze Check™ technology is available in the 0°C to –8°C range.
The patented Freeze Check™ consists of a clear, temperature-sensitive solution sealed in a transparent bubble that covers a green circle with a checkmark. The temperature-sensitive liquid is a multi-component, environmentally friendly solution. When the solution is exposed below the critical freezing temperature, the multiple components interact with each other and the clear solution turns white or opaque. The opaque material obstructs the view of the green circle, thus creating a visible sign that the package has been frozen.
The low profile packaging configuration makes Freeze Check™ ideal for placement on primary or secondary packaging, providing a reliable visual indication of temperature exposure. Further, the flexibility of the packaging is ideal for non-uniform packaging such as drums.
- Freeze Check is accurate and easy to use.
- Freeze Check is designed to be the most flexible freeze indicator on the market; it is tested to withstand 100 psi.
- Freeze Check does not require removal from package to determine if the product has been exposed to freezing temperatures.
- Competitor’s indicators require they be removed and either hit against a hard surface or shaken to determine if product has been frozen.
- Competitor’s indicators are easily knocked off as they are made of glass or rigid plastic that protrudes out from the indicator.
