MIL-PRF-81705 sets the standards for materials that protect static-sensitive components in military packaging from water vapor, static electricity, and electromagnetic interference.
This specification ensures that packaging for microcircuits and assemblies meets the Department of Defense requirements for water-vapor transmission, EMI attenuation, shielding, and mechanical strength.
Defense equipment is often exposed to extreme environmental conditions, including high humidity, salt exposure, rough handling, and limited storage control. Reliable moisture, static, and corrosion protection are essential for maintaining equipment integrity under these stresses.
No commercial equivalents meet the U.S. military’s strict standards for physical, mechanical, electrical, and corrosion resistance. As a result, materials must undergo extensive testing and approval through the Qualified Products Database (QPD). This process ensures that every material used in defense packaging meets official military specifications.
MIL-PRF-81705 is the U.S. military performance specification for flexible barrier materials used in protective packaging applications. It defines the requirements for shielding materials that prevent moisture, static, and electromagnetic interference (EMI) damage to sensitive components.
Type I materials combine moisture vapor protection, electrostatic discharge (ESD) protection, and electromagnetic interference (EMI) shielding in a single multilayer construction — ideal for electronics and defense components.
Class 1 materials are engineered for compatibility with both hand-operated and automated sealing equipment. This flexibility ensures consistent seals in diverse production environments, from manual packaging to high-speed automated lines.
Packaging Formats
MIL-PRF-81705F Type I, Class 1 material is versatile. It can be made into many types of packaging to fit your project’s needs. From small custom bags to large barrier solutions, 3D Barrier Bags, Inc. can provide what you need.
Converted into bags of any shape or size, tailored to your specifications.
Sheets can be heat-sealed into flat bags of any size, compliant with MIL-DTL-117 standards when required.
Available in 36", 50", and 59" widths to reduce waste and simplify processing.
To be listed in the Qualified Products Database (QPD), barrier materials must pass rigorous laboratory tests that verify their quality and performance. All testing is conducted on the final, production-ready material to ensure that nothing affects quality or compliance.
After the above testing is approved for use, the material must still meet additional identification requirements. All lettering should be clear and legible. It must be written in water-resistant ink and should be no less than 1/8th inch high (Group A) or no less than 1/2 inch high (Group B) and include the following information:
Manufacturers of data servers, electronic cabinets, circuit boards, and communication modules must protect their assemblies during transit and long-term storage. These systems are especially vulnerable to ESD, moisture ingress, and EMI. Any of these factors can degrade performance before deployment.
With 3D Barrier Bags, Inc.’s MIL-PRF-81705F qualified materials, assemblies can be sealed in static-shielding, moisture-barrier packaging to ensure military compliance and operational readiness.
Our certified materials combine low WVTR, EMI shielding, and electrostatic protection, preserving the integrity and reliability of complex electronic systems from manufacturing through deployment.
Beyond protection, this level of packaging assurance supports efficient logistics and long-term storage stability. Components can be shipped globally without repackaging or environmental concerns, maintaining their original performance characteristics. The materials’ proven resistance to humidity, temperature fluctuation, and handling stress ensures consistent outcomes in even the most demanding applications. By using defense-grade barrier films, manufacturers minimize the risk of latent failures, reduce field maintenance costs, and uphold quality standards essential for aerospace, defense, and advanced communication systems.
With 3D Barrier Bags, Inc.’s MIL-PRF-81705F qualified materials, assemblies can be sealed in static-shielding, moisture-barrier packaging to ensure military compliance and operational readiness.
