2. Moisture vapor transmission rate - Wikipedia

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

   The building materials industry also manages the moisture barrier properties in architectural components to ensure the correct moisture levels in the internal spaces of buildings. Optoelectronic devices based on organic material, generally named OLEDs , need an encapsulation with low values of WVTR to guarantee the same performances over the ...

3. Blister pack - Wikipedia

   en.wikipedia.org/wiki/Blister_pack

   The SBC grade has over twice the barrier to moisture and oxygen per gram coating weight compared to the historic grades. The most common structures using the super barrier PVDC are triplex configurations 250μ PVC/25μ PE/120gsm PVDC up to 250μ PVC/25μ PE/180gsm PVDC, with WVTR of 0.11 to 0.06 g/m 2 per day and available from various suppliers.

4. 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 ...

5. Drug packaging - Wikipedia

   en.wikipedia.org/wiki/Drug_packaging

   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.

6. Polychlorotrifluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polychlorotrifluoroethylene

   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,

7. Food packaging - Wikipedia

   en.wikipedia.org/wiki/Food_packaging

   Concurrently to the oxygen barrier property, the permeability of water vapor through a food packaging system should be minimized to effectively prevent physical and chemical changes connected to an excessive moisture content. [52] The moisture barrier properties of a material can be assessed by measuring the water vapor transmission rate (WVTR ...
