Bar Code Labels of DuPont™ Kapton®


Bar code labels for high temperature environments for printed circuit board applications.

Polyonics, Inc. of Westmoreland, NH, fabricates its bar code labels on 1 or 2-mil thick substrates of Kapton® HN polyimide film upon which an acrylic adhesive and one of several ink-receptive topcoats are applied. Polyonics is able to mix and match film thickness, topcoat chemistries and adhesives to meet its customers’ needs for harsh labeling applications. When printed with the appropriate ribbon, Kapton® label stocks endure the most hostile environments without overlamination.

Polyonics specializes in manufacturing printable label materials for harsh industrial environments including dot matrix, hot stamp, flexographic, laser jet, and thermal transfer barcode applications. Polyonics products withstand high-temperatures, chemicals, outdoor exposure, and ESD. They coat polyester, Kapton® polyimide, Nomex® aramid, Tedlar® polyvinyl fluoride, and other high performance films.

Polyonics materials are widely used across diverse industries such as electronics, wire and cable marking, aerospace, pharmaceutical, security and anti-counterfeiting, glass, metal, ceramic, and automotive.
