vacuum seal

Airtight preservation method

A vacuum seal is an airtight closure created by removing air from a container or package.

The absence of air pressure holds the seal tight and prevents spoilage by depriving bacteria of oxygen.

Vacuum sealing preserves food, protects documents, and packages items for storage: We vacuum sealed the steaks before freezing them.

As a verb, to vacuum seal is to create such a closure.
