Thermochromic Inks for Temperature-Sensitive Products

Thermochromic inks are temperature sensitive compounds that change color or disappear with variations in climate. These changes can be temporary or permanent depending on the application. 

This technology is often employed in instances where products need to be stored in controlled environments.  For example, in certain applications such as pharmaceuticals, vaccines, biologics or food, temperature variation or spoilage is a serious concern.  If kept at extreme temperatures, the products may be rendered useless, and this is obviously something to which users would need to be alerted. 

Note within the photo above, there are two containers of pre-workout.  The container on the left is at room temperature and features a label with a plain black thermo intensity background.  The container on the right has been heated by the consumer after taking the pre-workout.  Notice the thermo intensity background changed color from black to red. 

With Gintzler International, a Resource Label Group Co., thermochromic inks are available for both pressure sensitive and shrink sleeve labels, and the colors and temperatures can be customized based on the desired application.  This technology:

  • Enables designers to set the activating temperature range
  • Acts as a warning to healthcare professionals and patients
  • Alerts users when a tempera­ture threshold has exceeded a safe level for the product.
  • Allows shareholders within the supply chain to monitor temperature storage conditions 

Temperature sensitive inks are just one of the many technologies and techniques Gintzler can apply to packaging to help guarantee the integrity and authenticity of a product.  Contact a representative for more information at
