Product Description

Product Description

Impregnated with ZERUST® acid-gas scavengers, ICT®520-CB1 Anti-Tarnish films and bags protect silver and yellow metals such as copper, bronze, brass, and tin from the detrimental effects of oxidation and tarnish. Additionally, the anti-tarnish film does not leave a residue, preserving the functionality and aesthetic appeal of the protected items. Ideal for safeguarding valuable silver items, copper wiring, electronic components, and musical instrument strings, ICT®520-CB1 protects for years.

Furthermore, when used with other ZERUST® VCI products, the anti-tarnish film provides added protection for all metal types while preventing acid gases from entering the packaging. Compared to alternatives like foil or copper particle-infused films, the anti-tarnish film stands out for its cost-effectiveness, compatibility with automated packaging systems, and transparency. Engineered for a broad range of applications, ICT®520-CB1 is available in various packaging types, including rolls, sheets, tubing, and bags. In addition, additives such UV stabilizers, anti-block, slip, and anti-static additives are available to meet specific customer preferences, ensuring an ideal packaging solution.
