ARMOR Poly VCI Bags in 13" x 11" x 25" x 4 mil are a gusseted, heat-sealable industrial packaging solution combining barrier film protection with vapor-phase corrosion inhibition (VCI) for machined castings, ferrous and non-ferrous metal parts, and assemblies in domestic storage and export shipments. Manufactured using high-tech resins and precision extrusion technology, these bags provide both moisture barrier and active rust prevention in a single easy-to-use bag format. Packed 250 bags per case (43 lbs/case).

Specs: 13" x 11" x 25" (W x Gusset x L) | 4 mil | ARMOR VCI Poly | 250/Case | MIL-B-22019C / MIL-B-22020D Reference

Applications

Designed for manufacturers and distributors packaging machined castings, steel and aluminum stampings, precision metal assemblies, engine components, gears, shafts, and hydraulic fittings for warehouse storage, in-process protection between production stages, and export shipment packaging. The gusseted format accommodates irregular and bulky machined part geometries that flat bags cannot contain effectively.

Features

• ARMOR VCI formulation — vapor-phase corrosion inhibition for ferrous and non-ferrous metals


• Combined barrier and anti-corrosion protection in a single film — reduces packaging steps and material cost


• Heat sealable construction — creates a closed VCI environment to maintain inhibitor concentration


• 4 mil heavy-duty gauge — puncture and abrasion resistance for sharp-edged machined parts


• Gusseted 13" x 11" x 25" format — accommodates bulky or irregular 3D part geometries


• MIL-spec VCI performance reference — ASTM-tested corrosion inhibition efficacy

Material Notes

ARMOR Poly VCI film is engineered using a co-extrusion process that embeds VCI compounds throughout the film structure, ensuring corrosion inhibitor release from all surfaces of the bag interior. The 4 mil construction delivers heavy-duty puncture resistance appropriate for sharp machined edges and threaded fasteners. Film composition is optimized for both ferrous (steel, iron) and non-ferrous (aluminum, copper, brass) metal protection in the same bag.

Use Case Notes

The 13" x 11" x 25" gusseted format is sized for mid-range industrial components — large enough to accommodate a cylinder head or transmission housing and sufficiently gusseted to conform to irregular shapes without excessive void space. Metalworking operations use these bags between production stages to prevent oxidation during overnight or extended holds. Export packagers use them as the primary packaging layer before crating for long-duration ocean or air freight shipments to humidity-variable destinations.

Common Questions

Q: What metals does ARMOR VCI protect?
A: ARMOR VCI protects ferrous metals (steel, cast iron) and most non-ferrous metals including aluminum, copper, and brass. Verify compatibility for specific alloy applications.

Q: How should these bags be sealed for maximum VCI effectiveness?
A: Heat sealing is the most effective closure method. A heat-sealed bag creates a closed environment that maintains the VCI inhibitor concentration around the metal surface, maximizing protection duration.

Q: Are these bags reusable?
A: ARMOR Poly VCI bags can be reused if they are not punctured or torn and the seal integrity is maintained. Once opened, reseal immediately to preserve VCI efficacy. Extended reuse reduces VCI concentration and protection performance.

Why Buy

ARMOR Poly VCI bags combine barrier film and active corrosion inhibition into a single gusseted package, eliminating the need for separate desiccant packs or additional VCI emitters for most standard metal part storage and export applications. At 250 bags per case, they are an efficient stocking unit for MRO departments, precision machining operations, and export packagers with ongoing metal part protection requirements.
