Corrosion Intercept Pouches and Zipper Bags


[Intercept Technology, Inc.] A registered trademark for a series of products made from a patented plastic barrier film. Corrosion Intercept® was developed by Lucent Technology/Bell Labs, who then licensed the patent to Intercept Technology in 1983 for development and marketing. Corrosion Intercept® film contains highly reactive copper particles in an inert plastic (e.g. Polyethylene) matrix. This forms a reactive barrier for corrosive and oxidative gases. According to their website, Corrosion Intercept® (CI) has the more recognizable Copper color, but it is designed for lighter corrosion duties than Static Intercept®. CI is the preferred choice for museum, archival, and consumer applications for protection of Silver, Copper, Brass, Bronze, Iron, and Steel in addition to CDs, photographic prints, film, books, and works of art.
