Water Vapor Permeability of Plastic Fast Packs,

reportActive / Technical Report | Accession Number: ADA054509 | Open PDF

Abstract:

The objective of this investigation was to perform nondestructive tests that quantitatively measured the water vapor permeability of a plastic high density polyethylene Type I Fast Pack design. The water vapor transmission rate WVTR of the new pack design was found to be much less than the 0.02 grams100 square inch24 hour maximum allowed for the MIL-B-131 barrier material bags or pouches used in the original fiberboard Type I Fast Packs. The plastic Fast Pack container, itself, acts as the low WVTR barrier which protects against moisture penetration while the polyurethane foam cushioning affords mechanical and physical protection.
