MIL-PRF-81705 Barrier Materials, Flexible, Electrostatic Discharge Protective, Heat-SealableThis specification establishes the requirements for heat-sealable, electrostatic discharge protective, flexible barrier materials used for the military packaging of microcircuits, sensitive semiconductor devices, sensitive resistors, and associated higher assemblies. In addition, the type I materials provide for watervaporproof protection and attenuation of electromagnetic interference effects \(see 6.1\).
