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

   Drug packaging (or pharmaceutical packaging) is process of packing pharmaceutical preparations for distribution, and the physical packaging in which they are stored. It involves all of the operations from production through drug distribution channels to the end consumer.

5. Modified atmosphere - Wikipedia

   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. 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 ...

7. Humidity indicator card - Wikipedia

   en.wikipedia.org/wiki/Humidity_indicator_card

   A humidity indicator card (HIC) is a card on which a moisture-sensitive chemical is impregnated such that it will change color when the indicated relative humidity (RH) is exceeded. This has usually been a blotting paper impregnated with cobalt(II) chloride base; Less toxic alternatives include other chemicals such as cobalt-free chloride base ...

8. 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 ...

9. Vacuum packing - Wikipedia

   en.wikipedia.org/wiki/Vacuum_packing

   Once the product is placed in the machine on the seal bar, the lid is closed and air is removed. Then a seal bar inside the chamber seals the product in the bag, after sealing the bag the chamber is refilled with air by the automatic opening of a vent to the outside. This oncoming pressure squeezes all remaining air in the bag. The lid is then ...
