2. 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 ...

3. 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 ...

4. 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]

5. 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.

6. Polychlorotrifluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polychlorotrifluoroethylene

   moisture barriers in pharmaceutical blister packaging; water-vapour barriers 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; Due to its chemical stability, it acts as a protective barrier against ...

7. Multilayered packaging - Wikipedia

   en.wikipedia.org/wiki/Multilayered_Packaging

   Multi-layered packaging are multilayer or composite materials using innovative technologies aimed to give barrier properties, strength and storage stability to food items, new materials as well as hazardous materials. [1] Multiple layers are formed by coextrusion, lamination, or various coating technologies. The material of construction of ...

8. Parylene - Wikipedia

   en.wikipedia.org/wiki/Parylene

   Parylene was discovered in 1947 by Michael Szwarc as one of the thermal decomposition products of para-xylene H 3 C − C 6 H 4 − CH 3 above 1000 °C. Szwarc identified para-xylylene as the precursor by observing that reaction with iodine yielded para-xylylene di-iodide as the only product. The reaction yield was only a few percent. [1] [2]

9. Visqueen - Wikipedia

   en.wikipedia.org/wiki/Visqueen

   Visqueen is used as a condensation barrier inside walls when installing HVAC systems. It is also used as a ground cover in the crawl space of home foundations as a vapor barrier . [ 3 ] The use of Visqueen underneath a basement is to prevent water infiltration from water present in the ground that would pass through the concrete or dirt floor ...
