2. Moisture vapor transmission rate - Wikipedia

   en.wikipedia.org/wiki/Moisture_vapor...

   Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers. There are many industries where moisture control is critical.

   High barrier packaging (including seals) is necessary but, by itself, is often not enough. Shelf life of a moisture-sensitive drug can be extended by means of desiccants. [ 11 ] Several types of dessicants are available; the type and quantity need to be matched to the particular drug and package.

   PCTFE films are used as a protective layer against moisture. These include: moisture barrier in pharmaceutical blister packaging, water-vapour barrier for protecting phosphor coatings in electroluminescent lamps (the phosphor chemicals are sensitive to moisture), protection of liquid-crystal display (LCD) panels, which are sensitive to moisture,

6. Active packaging - Wikipedia

   en.wikipedia.org/wiki/Active_packaging

   For many years, desiccants have been used to control the water vapor in a closed package. A desiccant is a hygroscopic substance usually in a porous pouch or sachet which is placed inside a sealed package. They have been used to reduce corrosion of machinery and electronics and to extend the shelf life of moisture-sensitive foods. With ...
