Volatile Corrosion Inhibitor Masterbatch
Corrosion protection for packed metal parts, built into the film itself.
Volatile Corrosion Inhibitor Masterbatch protects metal parts from rust inside sealed plastic packaging. The film slowly releases a corrosion-inhibiting vapour that settles on the metal and forms an invisible protective layer. Used for steel coil, automotive, aerospace, electronic and defence packaging where parts must arrive corrosion-free.
A corrosion inhibitor masterbatch for LDPE and LLDPE film, with the active dispersed on a polyolefin carrier. Made into blown or cast film, it releases a protective vapour inside the sealed package. The vapour settles on exposed metal and forms a thin protective layer that stops rust forming. Used to protect steel and iron parts in transit and storage, with multi-metal grades for aluminium, copper, zinc and brass.

Key benefits
Long-term metal corrosion protection
Up to 24 months of rust protection inside sealed packaging, for steel, iron and multi-metal parts.
Vapour-phase action
Active molecules volatilise to reach recessed surfaces, threads and blind holes, no oil coatings or post-treatment needed.
Effective in sealed packaging
Engineered for VCI bags, films and wraps that protect components in transit, warehousing and long-term storage.
Reusable / recyclable wrap
LDPE-based VCI films and bags can be recycled with conventional polyolefin streams after use.
Applications
Frequently asked questions
What is VCI Masterbatch used for?
It releases a vapour inside sealed packaging that protects metal parts from rust and corrosion, with no oils or coatings to clean off. Typical uses include protective film, bags and liners for metal components.
Which polymers does it work with?
It is formulated on polyethylene and used to make protective film and bags. We match the grade to the metals you are packing.
Can I get a trial sample?
Yes. Share your base resin, end application and the metals you need to protect and the packaging format, and we will ship a matched grade for line evaluation along with a Certificate of Analysis.
Which metals does it protect?
Standard grades protect ferrous parts such as steel and iron, and multi-metal grades are available for aluminium, copper and zinc. Share your parts and we will advise a suitable grade.
What is the typical lead time?
Standard grades ship in 7 to 14 working days from order confirmation. Custom formulations matched to a specific application take 3 to 4 weeks. We confirm an exact timeline at the quote stage.
