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.

In addition to medical device and pharmaceutical applications such as sutures, scalpels, pre-filled syringes, artificial joints, catheters, surgical gloves, etc., the technology could provide security-driven packaging for valuable items such as gemstones, collectables, electronic components, documents, etc.
