Your Questions, Answered
MIL-PRF-131 is a US military performance specification for flexible barrier materials that create a moisture and vapor-proof seal around sensitive equipment. We use Class 1 certified materials, the highest protection tier under the spec, for equipment headed into long-term storage or international shipping. See our complete guide to MIL-PRF-131 for the full technical breakdown.
A crate protects against physical damage; it doesn't stop moisture, humidity, or corrosion. For equipment sensitive to those — electronics, precision instruments, unprotected metal surfaces, anything headed overseas or into long-term storage — the barrier bag goes inside the crate as a second layer of protection against what wood and foam can't stop.
Both, depending on what you need. Most clients have us build them together: the equipment is barrier-bagged and vacuum-sealed, then packed into a custom crate, in a single job with one timeline. Barrier bag packaging is also available on its own if you're handling the crating separately.
Aerospace components and avionics, precision electronics, military and defense hardware, optical equipment, medical devices, and anything else where moisture or corrosion during transit or storage would be expensive or unacceptable.
Yes. Every job includes a certificate of compliance, desiccant type and quantity used, and humidity indicator readings at the time of sealing — documentation you can pass along to your customer, your compliance team, or an inspector.
Barrier bag packaging is built into our standard crating timeline, most jobs completed in 2–3 business days. Tell us your deadline when you request a quote and we'll confirm.
