An example of the exillent barrier properties offered by our 15MFS21BTN MylarFoil bags:

We sent one of these MylarFoil bags sealed with 2 SMD reels and a 28g molecular sieve desiccant across the country and back to get real world data on the package environment during the journey. After 4 days, the relative humidity inside the foil bag dropped significantly and (even during the day where the temperature spiked) kept the environmental conditions below target levels.
