A hermetic seal is any type of sealing that makes a given object airtight (preventing the passage of air, oxygen, or other gases).The term originally applied to airtight glass containers but, as technology advanced, it applied to a larger category of materials, including metals, rubber, and plastics.
Hermetic storage is a method of using sealed, airtight units to control moisture and insects in stored dry agricultural commodities. The hermetic storage restricts gas exchanges between the internal and external environments and the stored commodity, maintaining the initial levels of moisture and controlling pests by the lack of oxygen .
They use hermetic storage technology to reduce loss of post-harvest cowpea (Vigna unguiculata) due to bruchid infestations in West and Central Africa. [3] A PICS bag consists of two layers of polyethylene liners and a layer of woven polypropylene. [4] Each layer is closed separately to create a hermetically sealed container for harvested grain.
Integrated circuit packaging is the last assembly process before testing and shipping devices to customers. Occasionally specially-processed integrated circuit dies are prepared for direct connections to a substrate without an intermediate header or carrier. In flip chip systems the IC is connected by solder bumps to a substrate.
Equipment used in aseptic processing of food and beverages must be sterilized before processing and remain sterile during processing. [1] When designing aseptic processing equipment there are six basic requirements to consider: the equipment must have the capability of being cleaned thoroughly, it must be able to be sterilized with steam, chemicals, or high-temperature water, sterilization ...
A hermetic package allows essentially no gas exchange with the surroundings; such construction requires glass, ceramic or metal enclosures. This replica of the first laboratory transistor shows connecting leads and a glass jar for protection; packaging the device was critical to its success.
Steer clear of products with bloated packaging at the store. It's a food safety issue—here's why. The post If You See Bloated Food Packaging, This Is What It Means appeared first on Reader's Digest.
Packaging is the science, art and technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of designing, evaluating, and producing packages. Packaging can be described as a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use ...
