2. Moisture vapor transmission rate - Wikipedia

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

   It is a measure of the permeability for vapor barriers. There are many industries where moisture control is critical. Moisture sensitive foods and pharmaceuticals are put in packaging with controlled MVTR to achieve the required quality, safety, and shelf life.

3. Drug packaging - Wikipedia

   en.wikipedia.org/wiki/Drug_packaging

   Many dry pharmaceuticals are sensitive to moisture. Tablets may become unstable and the drug may degrade. 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]

4. Blister pack - Wikipedia

   en.wikipedia.org/wiki/Blister_pack

   Polychlorotrifluoroethylene (PCTFE) [8] can be laminated to PVC to obtain very high moisture barrier. Typical constructions used for pharmaceutical products are 250μ PVC film laminated to 15μ-150μ PCTFE film. Duplex structures are PVC/PCTFE and triplex laminates are PVC/PE/PCTFE. Deeper cavities can be formed by using the triplex structures ...

5. 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,

6. Active packaging - Wikipedia

   en.wikipedia.org/wiki/Active_packaging

   The terms active packaging, intelligent packaging, and smart packaging refer to amplified packaging systems used with foods, pharmaceuticals, and several other types of products. They help extend shelf life, monitor freshness, display information on quality, improve safety, and improve convenience. [1]

7. Modified atmosphere - Wikipedia

   en.wikipedia.org/wiki/Modified_atmosphere

   In contrast, chamber machines are used for batch processes. A filled pre-formed wrap is filled with the product and introduced into a cavity. The cavity is closed and vacuum is then pulled on the chamber and the modified atmosphere is inserted as desired. Sealing of the package is done through heated sealing bars, and the product is then removed.
