Freeze Alerts

Chromatic Technologies (CTI) invented the first-ever commercially printable BlindSpotz™ Freeze Alert technology for pharma, chemicals, and food. Watch this video to see it in action: 

This patent-pending innovation can be printed on aluminum, glass, plastic, paper labels, or film to identify if a product has been damaged by freezing. It’s highly accurate, reliable, low-cost, and developed to ensure safe and high-quality supply chain at the package or even individual product level.

According to the Gates Foundation and World Health Organization, 75% of vaccines may be exposed to freezing temperatures, but there has been no low-cost, practical freeze-alert diagnostic until now. Contact us today to see how BlindSpotz™ Freeze Alert might be the solution for your brand or customer.

Vaccines with Cold-Chain Packaging Solutions


7 of 10 leading pharmaceutical products require temperature-controlled transportation and just 2°C of temperature variation could completely ruin a pharmaceutical shipment.


Freezing temperatures can affect the quality of a food product and the health of consumers. The shipment needs to be evaluated at each step throughout the supply chain and in storage before reaching the end customer.


When a paint, coating or chemical has been frozen, the effectiveness of the product can decline. Unfortunately, a consumer doesn’t know that the product’s quality has been compromised until the product is in use.
