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.

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.

Cold Chain Product Management


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.
