Cortec VpCI-126 MIL is qualified to MIL-PRF-22019D Type 1. Cortec also cites Naval Air Warfare Center Aircraft Division QPL reference 43500B120-3/531 for VpCI-126 Blue.

How This VCI 50 Cal Ammo Can Liner Works
VCI stands for Vapor Corrosion Inhibitor. Inside the sealed liner, the VCI layer releases protective molecules into the enclosed air space around the stored contents.
Those molecules settle on exposed metal surfaces and help reduce oxidation before rust starts. The barrier layers also help reduce outside moisture and oxygen transfer.
This helps the protective environment stay focused inside the liner instead of off-gassing into the surrounding area.

VCI Ammo Can Liner FAQs
How long does this VCI 50 Cal Ammo Can Liner work?
With proper use, it can help protect contents for 5-10 years. Actual performance depends on storage conditions and how often the liner and can are opened.
Are ammunition, primers, and powder safe inside the liner?
Yes. API’s ammo storage pages state that VCI leaves no residue behind, so ammunition powder and primers are safe inside the liner.
Do I need desiccant packs or oxygen absorbers?
No. They can be used if desired, but they are not required. They also should not be placed in direct contact with bare metal surfaces.
Can ammo stay in factory packaging inside the liner?
Yes, as long as the inner tray is hard plastic and not Styrofoam. That helps preserve fit while still allowing the liner to do its job.
