Rollprint Announces Color-Changing Sealant Technology for Flexible Applications Requiring Additional Security, Branding Advantages

Addison, Ill.—Rollprint Packaging Products, Inc., which first developed the foil header pouch in the 1970s, is once again introducing a game changer—its proprietary color-changing sealant technology for heat-seal applications. 

The coextrusion-coated sealant can be applied to any thermally-stable web including polyester, nylon and polypropylene or on any of the company’s ClearFoil® barrier structures.  Chevron pouches and lidding materials for trays are expected to be the first commercialized applications.

The technology, a year in development, has been engineered to allow a film of one color to transfer a peel indicator of a different color providing strong visual indication that a package has been opened. The objective is to enhance product security and help deter counterfeiting, in a cost-effective manner. 

The sealant, which is applied across the entire web, can accommodate many color combinations to help support branding initiatives. 

“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, Rollprint.

Not only does the new technology enhance security, but it also offers medical device and pharmaceutical manufacturers a new way to communicate branding attributes or color code products by type or size.  The transparent nature of the color application still allows contents to be visible.

“These market segments typically have not used visual elements to support brands to the degree that other categories have.  We view this new sealant technology as a game changer to help manufacturers grow market share, while also enhancing security,” Hahn said.

In addition to medical device and pharma applications such as sutures, scalpels, pre-filled syringes, artificial joints, catheters, surgical gloves, etc., Rollprint envisions other uses for the technology.  Security driven packaging for valuable items such as gemstones, collectables, electronic components, documents, etc., is also a target.

The web can be made up to 65-inches wide and can also be flexographically-printed for additional brand support.
