See-Through Flexible Barrier Bags Built to MIL-PRF-22191 and MIL-DTL-117
Military Packaging supplies transparent barrier bags made to MIL-PRF-22191, the military specification for transparent, flexible, heat-sealable barrier material. Built to seal moisture out while letting you see the contents, MIL-PRF-22191 bags protect parts and electronics through storage and transit without hiding what is inside. Order them on their own or built into a complete preservation system we design around your equipment.
MIL-PRF-22191 is the military specification for transparent, flexible, heat-sealable barrier material. It defines the see-through films used to build the bags that protect parts from moisture and contamination while keeping the contents visible.
The material seals moisture and vapor out the way a barrier bag should, but stays clear instead of opaque like foil. That lets your team read a label, identify a part, or inspect the contents without opening the seal and starting the protection over.
We supply bags built from MIL-PRF-22191 material and constructed to MIL-DTL-117, so you get both the barrier the spec requires and the bag construction your program calls out. When a drawing calls for MIL-PRF-22191, this is the bag it means.
Every MIL-PRF-22191 bag we supply protects the contents while keeping them visible:
The specification defines what makes a compliant transparent barrier material:
MIL-PRF-22191 defines types and classes that set the barrier level and film properties. The right one balances how much moisture protection the contents need against the clarity and flexibility the application calls for, so you get a bag that both protects and shows the part.
We help you read the callout and supply the type your drawing requires, or recommend one when the choice is open. Send us the spec and the part, and we will confirm the right MIL-PRF-22191 bag for the job.
MIL-PRF-22191 bags protect the parts that need to stay visible across a defense shipment:
MIL-PRF-22191 bags protect the parts these sectors ship, store, and preserve every day:
A few factors point you to the right MIL-PRF-22191 bag. Weigh these, or send us the part and we will recommend one:
A MIL-PRF-22191 bag is the sealed, see-through layer around a part. It seals moisture out while keeping the contents visible, and it gives the pack a clean, compliant closure. The outer packaging builds outward from there.
Sourced as one system, the bag is matched to the desiccant, wrap, and container around it, so a part travels protected and identifiable from the bag out to the shipping carton.
A foil barrier bag protects moisture-sensitive parts perfectly, but it hides them. Every time someone needs to identify or inspect the contents, the seal has to be broken and the protection restarted. A transparent barrier bag removes that trade-off.
With MIL-PRF-22191, your team reads the label, counts the parts, or checks the humidity indicator through the bag, without opening it. For kits, receiving inspection, and stock that gets checked often, that visibility saves time and keeps the seal intact.
The choice between transparent and foil comes down to barrier versus visibility. Foil per MIL-PRF-131 delivers the highest moisture barrier but is opaque, while transparent film per MIL-PRF-22191 lets you see the contents with a barrier suited to many applications.
We help you weigh the two. When the longest, most demanding preservation is the priority, foil wins, and when identification and inspection matter, transparent is the answer. Tell us the part and the storage, and we will recommend the right bag.
Transparent barrier bags handle moisture, but static-sensitive electronics need shielding too. When a part faces both threats, we pair the right bags or move to a static-shielding barrier, so the electronics are protected from discharge as well as humidity.
We match the protection to the part, using a transparent bag where visibility and moisture control are the priority and a shielding bag where static is the concern. Tell us the part and we will build the right combination.
Reading a barrier callout and building the right bag is what we do. Our team helps buyers and packaging engineers match the MIL-PRF-22191 type and MIL-DTL-117 bag to the part, size the desiccant, and meet the preservation spec.
Send us the part, your storage timeline, and any spec callouts, and we will recommend the right MIL-PRF-22191 bag and quote it, so your parts ship protected and identifiable from the first shipment.
Every program defines moisture protection a little differently, and we build to yours. When your documentation names a MIL-PRF-22191 type, a bag construction, or a preservation method, we match it exactly. When the choice is open, we recommend the barrier that fits the part and the conditions.
That flexibility means your packaging satisfies the spec and keeps the contents protected and visible in practice, with no gap between the two.
A MIL-PRF-22191 bag does its best work as part of a full system. We seal the part in the transparent bag with a desiccant and humidity indicator, wrap sensitive surfaces, cushion against shock, and enclose the pack in a box or crate rated for the journey. Sourced together, these layers protect the part and let your team see it at a glance.
We supply bags that meet MIL-PRF-22191 for the barrier material and MIL-DTL-117 for the bag construction, and we build them into packaging that satisfies your spec. Where your drawing cites the material type or the bag construction, we match it.
Where the drawing leaves a choice, we recommend the barrier and construction that best protect your part. Either way, you get moisture protection you can ship on and see through.
Tell us what you are protecting, the size of the part, whether you need to see the contents, and any spec callouts, and we will recommend the right MIL-PRF-22191 bag.
We supply MIL-PRF-22191 bags on their own or as part of a complete preservation system, with availability and turnaround confirmed in your quote.
We supply transparent barrier bags built to MIL-PRF-22191 and MIL-DTL-117, and we know how to build them into a compliant, sealed system.
That combination keeps parts protected and identifiable, and ready to use after shipping and long storage.
MIL-PRF-22191 is the military specification for transparent, flexible, heat-sealable barrier material. It defines the see-through films used to make barrier bags that seal moisture out while keeping the contents visible.
Foil delivers the highest moisture barrier but hides the contents. A transparent MIL-PRF-22191 bag lets you identify parts, read labels, and check a humidity indicator without opening the seal, which matters for kits and inspection.
Both are barrier materials, but MIL-PRF-131 is an opaque foil laminate with the highest moisture barrier, while MIL-PRF-22191 is transparent so you can see the contents. We help you choose based on barrier level versus visibility.
MIL-PRF-22191 governs the transparent barrier material, while MIL-DTL-117 governs the finished bag made from it. We build a MIL-DTL-117 bag from MIL-PRF-22191 material, so both specs are satisfied.
Yes. Sealed with a desiccant, a transparent barrier bag holds a controlled-humidity environment, and because it is clear, your team can read the humidity indicator through the bag without opening it. We size the desiccant to the bag.
Yes. We supply bags built to MIL-PRF-22191 for the barrier material and MIL-DTL-117 for the bag construction, so they satisfy the requirements defense programs call out. Send us your callout and we will confirm the type.
