White Bags

[Scott Wilson]

I have a few of these storage bags and wonder what they were meant to store. They measure 29 1/2" by 9".47904

One of the more barrier materials used in Mil-Spec packaging is – MIL-PRF-131 Class 1- (or MIL-DTL-117 Type 1, Class E, Style 1 when this material is used in BAG form) . It is used when the government needs a moisture sensitive item packaged in a moisture controlled environment. This is why they call it Barrier Material. It acts as a barrier between the outside air and the part which is sealed inside the barrier bag.

MIL-PRF-131 Class 1 Replaced MIL B 131E.
