How to Package for Military Spec and Long-term Storage

Steps

1. Read the contract or purchase order first. It names the standard (usually MIL-STD-2073-1 or MIL-STD-129 for marking) and the method to use.
2. Clean and dry the part before packing. Moisture or oil sealed inside the bag will cause corrosion later.
3. Pick the barrier material using the table below.
4. Add desiccant sized to the bag and storage time, plus a humidity indicator card so receivers can check the pack without opening it.
5. Remove excess air, heat seal the bag with a constant-heat sealer, and check the seal along its full length.
6. Mark and label the package as the contract requires, including part number, NSN, and pack date.

• Using the wrong bag class or method because the contract wasn’t checked. This leads to rejected shipments.
• Too little desiccant for long storage, or desiccant left open to air before packing, which uses it up.
• Sealing foil bags with an impulse sealer made for thin poly, which leaves weak seals.

You have a government or defense contract, need mil-spec bags, paper bags, or tubes, or want help reading a packaging requirement.
