How Moisture Barrier Bags Work
moisture barrier bags work by enclosing a device with a metal or plastic shield(s) that
has a high resistance to moisture vapor permeation. dry devices are placed inside this
shield, and the moisture-laden air is evacuated. desiccant filled pouches scavenge the
remaining moisture from the bag’s interior. moisture that penetrates the bag is also
entrapped by the desiccant. Humidity indicating cards report the effectiveness of the
package upon device use. a label on the bag indicates the amount of exposure time
devices are allowed prior to use, and the drying (re-baking) time and temperature if the
exposure time is exceeded.
as the barrier property improves, the moisture Vapor transmission rate (mVtr)
decreases. bags with lower mVtr provide better barrier. aluminum foil provides the
best mVtr of about 0.0003. multiple layers of aluminized Polyester can provide 0.02
to about 0.005.
Puncture resistance is an important feature for barrier bags. sharp tray edges may
tear through bags with low puncture resistance.
