Barrier Bags
Barrier bags provide multi-layer protection against moisture, oxygen, electrostatic discharge (ESD), and physical damage. Commonly used for packaging moisture-sensitive devices (MSDs), electronic assemblies, and components that require controlled humidity environments. Valley ProPac sources barrier bags through qualified manufacturing partners with MIL-PRF-81705 and J-STD-033 capability.
