Bearing & Precision Gear VCI Bags 4" x 6" — 4 mil ARMOR Poly

These 4" x 6" ARMOR Poly VCI bags deliver volatile corrosion inhibitor protection in a compact, high-volume format for small metal component packaging. The ARMOR VCI film technology releases corrosion-inhibiting molecules that form a protective layer on bearing races, gear teeth, threaded fasteners, and other precision machined surfaces — eliminating the need for rust-preventive oils or desiccants. At 4 mil, the bags hold up against sharp thread profiles and metal edges in high-speed production and kitting environments. Case-packed at 5,000 bags for industrial volume use.

Specs: 4" x 6" | 4 mil | ARMOR Poly VCI Film | 5,000/Case | Non-Food

Applications

• Ball bearing and roller bearing individual protective packaging


• Precision spur gear, pinion, and sprocket storage and distribution


• Threaded fastener kitting for export and domestic distribution


• Cutting tool — drill bit, tap, and end mill corrosion protection between runs


• Small machined part interplant transfer during in-process manufacturing


• MRO parts distribution for corrosion-sensitive hardware in humid environments

Features

• ARMOR Poly VCI film — volatile corrosion inhibitor chemistry for ferrous and non-ferrous metals


• 4 mil gauge — puncture-resistant for threaded fasteners and metal components with sharp profiles


• 4" x 6" compact format — right-sized for bearings, small gears, and similar precision components


• No rust-preventive oils, greases, or desiccants required — VCI provides clean, dry protection


• Heat sealable for fully enclosed corrosion protection environment


• 5,000 bags per case for high-throughput kitting and packaging operations

Material Notes

Manufactured using ARMOR's high-tech VCI resin extrusion technology. The film provides dual-function protection: a physical barrier against moisture and particulate contamination, and active corrosion inhibition via VCI chemistry that volatilizes within the sealed bag environment. Compatible with ferrous metals (steel, cast iron) and non-ferrous metals (aluminum, copper alloys). The 4 mil gauge is appropriate for components with threads, machined edges, and bearing race profiles. All stated gauges are nominal.

Use Case Notes

The 4x6 format accommodates standard ball and roller bearings up to approximately 3.5" x 5.5" in footprint. For bearing kitting operations, seal each bearing individually before placing in a shipping carton or bulk bin — the individual VCI environment provides complete corrosion protection without inter-part contact. For cutting tools and threaded fasteners, group by size and seal in individual bags for clean kitting presentation. The 5,000-count case quantity supports production-line kitting operations without frequent restocking interruptions.

Common Questions

Q: How long does VCI protection last in a sealed bag?

A: In a properly heat-sealed ARMOR VCI bag under normal indoor storage conditions, corrosion protection typically lasts 12–24 months. Protection is reduced if the bag is opened or stored in extreme heat or humidity conditions.

Q: Does the VCI film leave residue on bearings or precision parts?

A: ARMOR VCI film is formulated for residue-free protection in most standard applications. Precision parts can typically be installed or used directly from the bag without additional cleaning, though high-precision applications should verify compatibility with specific surface finishes.

Q: Are these bags compatible with non-ferrous metals?

A: Yes. ARMOR VCI chemistry is formulated to protect both ferrous (steel, cast iron) and non-ferrous metals (aluminum, copper, brass). For mixed-metal assemblies or exotic alloys, verify compatibility with ARMOR technical specifications before large-scale deployment.

Q: Can these be used for export packaging?

A: Yes. ARMOR Poly VCI bags are suitable for domestic and export shipment applications. For extended export transit or high-humidity destinations, heat seal completely to maximize VCI concentration and protection duration.

Why Buy

Bearing distributors, gear manufacturers, and MRO hardware suppliers use ARMOR Poly VCI bags because they eliminate the labor cost of oil-based rust prevention while delivering reliable corrosion protection in a clean, compact format. The 4x6 size covers the most common small precision component footprints, and the 5,000-count case quantity supports high-volume kitting operations without restocking interruptions. Sourced from a wholesale packaging distributor with consistent ARMOR specification and reliable availability.
