Color-Changing Sealant Technology Enhances Package Security

Rollprint Packaging Products’ new, patent-pending, color-changing sealant technology is appropriately named Chameleon; it enhances product security with a color change indicating that a pouch or tray lid has been opened.

“When you peel open a standard chevron pouch, there is a subtle white indicator to show that the contents have been accessed. What we’ve done is engineer a way to leave a strong visual reference with a desired color,” explained Dwane Hahn, vice president of sales and marketing at Rollprint, in an Oct., 2012 press release.  The color-changing sealant can be used in pharmaceutical applications such as prefilled syringe packaging.  It can also be used for a wide range of medical device packaging and, outside the medical field, for electronic components or valuable items for which security and anticounterfeiting is a concern. The sealant can accommodate many color combinations, which gives manufacturers a new way to enhance their brand or to color code products.

This technology is another new weapon in the ongoing fight to thwart counterfeiting.
