VCI Packaging Films

Natur-VCI® Biodegradable VCI film is engineered for end-of-life disposal in industrial composting environments. Under controlled conditions, microorganisms break down the material by consuming its carbon content, converting it into water, carbon dioxide, and nutrient-rich organic matter that can be used as a soil amendment. This makes it a practical solution for organizations seeking to reduce packaging waste and support circular economy initiatives.

The film meets internationally recognized compostability standards, including ASTM D6400 and EN 13432, and is certified compostable by TÜV Austria. In addition to its environmental benefits, it also meets corrosion protection performance requirements such as NACE TM0208 for vapor-phase inhibition.

This Biodegradable VCI solution releases ZERUST® Vapor Corrosion Inhibitors into the enclosed packaging space. These invisible and odorless molecules form a protective layer on exposed metal surfaces, helping prevent rust and corrosion caused by moisture and environmental contaminants. Once the packaging is removed, the protective layer dissipates naturally, leaving metal parts clean and ready for immediate use without additional processing.

Natur-VCI® is suitable for protecting a wide range of components, including machined parts, castings, engines, and fabricated assemblies. It is available in multimetal formulations and various formats such as rolls, sheets, tubing, and bags, making it adaptable to different packaging needs. This combination of corrosion protection and sustainability makes it an ideal choice for companies looking to reduce environmental impact without sacrificing performance.

An added advantage of this Biodegradable VCI packaging is its potential for reuse within waste management programs. Used bags can be repurposed for collecting organic waste and directed to industrial composting facilities, supporting zero-waste initiatives when used in accordance with composting guidelines.

Benefits:

Metal Types:

ZERUST® Natur-VCI® Biodegradable VCI film provides multimetal corrosion protection for a wide range of metals, including ferrous alloys, aluminum, copper, brass, and zinc. Due to the higher water vapor transmission rate compared to traditional polyethylene films, it is important to evaluate application conditions when protecting yellow metals in high-temperature or high-humidity environments.

Availability:

ZERUST®/EXCOR® Natur-VCI® Biodegradable VCI Film is a made-to-order solution designed to meet specific application and sustainability requirements. A wide range of custom options are available, subject to minimum order quantities. Contact your ZERUST® representative for ordering information.
