MIL-DTL-22020 Type I VCI Barrier Bags

MIL-DTL-22020 Type I VCI Barrier Bags – Corrosion Protection for Military and Industrial Applications

MIL-DTL-22020 Type I Barrier VCI Material storage bags are designed for long-term, moisture-resistant, and corrosion-inhibiting packaging of metal components. These durable barrier bags meet U.S. Department of Defense requirements and are ideal for military, aerospace, and heavy manufacturing applications where rust prevention and material preservation are critical.

These high-performance VCI (Vapor Corrosion Inhibitor) bags offer contactless corrosion protection for both ferrous and non-ferrous metals while also acting as a robust moisture and vapor barrier.

What Is MIL-DTL-22020?

MIL-DTL-22020 is a military detail specification for flexible barrier materials that provide moisture vapor protection along with VCI-based corrosion inhibition. These materials are used to create bags, wraps, and covers for sensitive metallic items that require long-term preservation under demanding conditions.

Type I Overview:

  • Type I: Flexible film or bag format

  • Contains VCI compounds that release corrosion-inhibiting vapors

  • Designed to meet moisture vapor transmission rate (MVTR) and durability criteria

  • Compliant with MIL-STD-2073 and MIL-STD-129 packaging standards

Key Features of MIL-DTL-22020 Type I Barrier Bags

  • ✅ Vapor Corrosion Inhibitor (VCI) technology embedded in the material

  • ✅ Contactless rust prevention for steel, aluminum, brass, copper, and more

  • ✅ Moisture and oxygen barrier to prevent oxidation

  • ✅ Flexible film or bag construction for ease of use

  • ✅ Heat-sealable or resealable options available

  • ✅ Meets U.S. military durability and preservation specs

These bags can eliminate the need for messy oils, greases, or desiccants in many corrosion-sensitive packaging applications.

Common Uses for MIL-DTL-22020 Type I VCI Bags

1. Military and Defense Component Preservation

These VCI bags are widely used to store and ship metal parts, assemblies, tools, and munitions in compliance with DoD logistics and storage requirements.

2. Industrial Equipment Packaging

Ideal for packing machined parts, bearings, castings, gears, and engines where oxidation during transport or storage is a concern.

3. Export and Long-Term Storage

MIL-DTL-22020 Type I bags are essential for products shipped overseas or stored in high-humidity or corrosive environments, where traditional barriers may fail.

4. Aerospace and Aviation Supply Chains

Used for packaging aircraft components and tooling, where both corrosion and moisture can compromise product reliability.

5. Kitting for MRO and Spare Parts

These bags are perfect for maintenance, repair, and overhaul (MRO) kits that contain metal tools or replacement parts.

Advantages of VCI Barrier Bags

  • Dry corrosion protection – no need for oils or surface treatments

  • Cleaner packaging process – ideal for cleanroom or assembly-line use

  • Extended shelf life for metal parts

  • Prevents corrosion even in sealed or vacuum-packed conditions

  • Military-compliant labeling and documentation options

How VCI Barrier Bags Work

VCI molecules are embedded into the film and slowly release vapor that forms an invisible protective layer on metal surfaces inside the bag. This vapor layer:

  • Prevents corrosion and oxidation

  • Is non-toxic and residue-free

  • Does not require direct contact with the item

  • Works in sealed environments for up to 24 months or more

For best results:

  1. Ensure metal parts are clean and dry.

  2. Place the item inside the MIL-DTL-22020 Type I bag.

  3. Seal the bag using a heat sealer or zip-top if available.

  4. Store in a cool, dry area away from UV exposure.

Compliance & Documentation

All MIL-DTL-22020 Type I barrier bags are manufactured under strict quality control protocols and are supplied with:

  • Certificate of Compliance (COC)

  • Lot traceability documentation

  • Labeling per MIL-STD-129 and MIL-STD-2073

These bags help meet procurement guidelines for NSN-based supply chains, government contracts, and GSA packaging regulations.
