Low Temperature Self-Sealing Vacuum Packaging

A method and system involves vacuum sealing a semi-enclosure at room temperature without requiring mechanical actions within the vacuum chamber. The semi-enclosure has an inlet channel that extends inwardly into the vacuum chamber from an exterior opening (entryway) into the semi-enclosure. An uncured entryway vacuum sealant is provided at the entryway for the semi-enclosure. A vacuum is established in the vacuum chamber until the vacuum pressure reaches a desired vacuum pressure that causes the uncured entryway sealant to be provided to the entryway for the semi-enclosure. The uncured entryway vacuum sealant is cured under vacuum pressure in the semi-enclosure in the vacuum chamber.
