When components rust in storage or transit, you don’t just lose parts—you lose time, productivity and profit. For purchasing teams and facilities managers in manufacturing and engineering, preventing corrosion is a constant battle. Fortunately, VCI grip seal bags offer a clean, efficient and reliable solution that beats traditional greases and desiccants.
What Are VCI Grip Seal Bags and How They Work
VCI (Volatile Corrosion Inhibitor) grip seal bags are polyethylene pouches impregnated with corrosion-inhibiting compounds. Once sealed, these compounds vaporise and deposit an invisible molecular layer on metal surfaces. As a result, oxygen and moisture can’t trigger rust or oxidation.
Additionally, unlike oil-based methods, VCI packaging leaves no residue—so you skip the degreasing step and speed up your assembly or inspection processes.
Common Applications for VCI Minigrip Bags
VCI grip seal bags stand out for versatility. In fact, they protect:
- Bearings, gears, fasteners and precision tools against corrosion during storage or multi-leg shipments.
- Automotive and aerospace parts—from stamped panels to critical fasteners—where strict quality standards leave no room for rust.
- Electrical contacts or terminals prone to oxidation. A thin, clean VCI film preserves conductivity without lubricant contamination.
- Sample kits for customer trials, so prototypes arrive showroom‑clean and ready for demonstration.
They excel wherever you need dry, residue-free protection—particularly in cleanrooms or regulated assembly environments.
VCI Polythene Products: Broad Protection for Every Metal
Whether you’re dealing with low-value stamped components or ultra‑high-value machined assemblies, VCI polythene products deliver consistent protection. In storage, shipping or extended transport, this corrosion inhibition system keeps your stock ready for immediate use—no extra cleaning, no downtime.
Sourcing VCI Bags That Fit Your Needs
Off‑the‑shelf sizes cover most use cases, but sometimes you need something bespoke. At Polycopy, we stock a range of VCI minigrip bags in regular and large dimensions, providing rust protection for handling of everyday parts and also for bulkier items e.g. engine blocks.
Of course, if your project demands unique sizes or special thicknesses, we can manufacture to order. That way, you get packaging designed around your workflow—not the other way around.

Final Thoughts – Don’t Let Corrosion Eat Into Your Margins
Corrosion seldom announces itself until it’s already damaged your parts. By contrast, VCI grip seal bags provide proactive, low‑maintenance protection that supports lean manufacturing and just‑in‑time delivery. If you still rely on oils, grease or desiccant mixes, it’s time to explore a cleaner alternative.
