VCI Film

What is VCI Film?

VCI (Volatile Corrosion Inhibitor) film is a specialised packaging material that protects metal from corrosion during storage and transit. It releases volatile molecules that settle on metal surfaces and form a protective layer, shielding them from the moisture, oxygen and other corrosive elements that cause oxidation. Available as rolls, bags and sheets, it suits a wide range of packaging needs and is used across automotive, aerospace, electronics and defence, wherever metal parts need long-term protection. It is valued for its effectiveness, ease of use and cleaner, more eco-friendly profile than oils or loose desiccants, keeping parts corrosion-free right through the supply chain.

How does VCI film work?

VCI film releases corrosion-inhibiting molecules into the air around the metal. These molecules adsorb onto every metal surface, including recesses and threads, and form a molecular layer that interrupts the electrochemical reactions that cause rust. The layer is self-replenishing, so protection continues even after the pack is opened and resealed. BENZ VCI film is non-toxic, residue-free and safe on both ferrous and non-ferrous metals, keeping components in optimal condition through long storage and transport.

How to wrap VCI film on metal

Wrapping metal in VCI film is straightforward:

Prepare the surface. Make sure the metal is clean and free of dirt, oils and other contaminants, which can reduce the film's effectiveness.
Cut to size. Measure and cut the film to fit the part; it trims easily with scissors or a utility knife.
Wrap the part. Cover the whole surface and keep the film snug to minimise air pockets.
Seal the edges. With a bag or larger sheet, seal the edges with tape, heat sealing or VCI closures to keep moisture and air out.

How long does VCI film last?

Protection life depends on the film formulation, the storage conditions and the length of the journey, and typically ranges from several months to a few years. We supply VCI film in different grades tuned to specific protection windows, such as 6 months, 12 months or longer, so it can be matched to your route and storage.

VCI Film Manufacturer in India

BENZ Packaging is a leading Indian manufacturer of VCI film for protecting metal components in storage and transport. Our films are made from high-quality polyethylene (PE) or polypropylene (PP), infused with corrosion inhibitors and produced in a range of thicknesses to suit different applications. They are heat-sealable, transparent for easy inspection, tear-resistant and compatible with most packing methods, and they are made to rigorous quality and environmental standards, which makes them a dependable choice for automotive, aerospace, electronics and metal manufacturing. We also manufacture and supply VCI paper and VCI bags.

Our advanced VCI films and bags are engineered with high-technology resins and a custom co-extrusion process for higher mechanical strength and low water-vapour permeability. A VCI additive is introduced during co-extrusion and sublimes from the film to protect the packed metal. Trusted by leading automotive manufacturers, steelmakers and metallurgical companies worldwide, our VCI film is an easy, practical and cost-effective way to prevent corrosion, and its transparency lets goods be identified and cleared through customs without opening the pack.

BENZ VCI film is built in three layers, each with a job:

The inner layer gives immediate protection to the packed items.
The middle layer acts as a reservoir of VCI molecules, sustaining protection once the inner layer is depleted.
The outer layer is a barrier against the atmosphere and keeps the VCI action contained, so the full protective effect stays inside the pack.
