Water Vapor Permeability of Plastic Fast Packs,

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 grams/100 square inch/24 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.
