hermetic seal
An hermetic seal is the quality of something—a container, structure, etc.—being airtight (excluding passage of air, oxygen, or other gases). Used technically, it is stated in conjunction with a specific test method and conditions of use.
==Etymology ==
The word ''hermetic'' comes from the Greek god Hermes, via the vocabulary of alchemy. The alchemists invented a process for making an airtight glass tube, which they used for distillation. The process used a secret seal, whose invention was attributed to the legendary inspiration of alchemy, Hermes Trismegistus.
