What does sealed mean?
Sealed describes something that has been closed, secured, or protected so that it cannot easily be opened, altered, or inspected. The word is common in descriptions of envelopes, containers, records, rooms, and official documents. In legal and administrative contexts, a sealed bid, sealed record, or sealed document is one that must remain confidential until an authorized time or condition is met. Sealed can also mean finalized, as in a sealed decision, or fitted with a protective or official seal. Its implication is generally stronger and more deliberate than that of closed: a closed door may merely be shut, whereas a sealed door or package has been deliberately secured. The word consequently carries associations of protection, authenticity, confidentiality, and finality.
Closed or secured so that the contents cannot be accessed, escaped, or easily altered.

This is the past tense and past participle of seal.
From legal bids to mystery stories, sealing something often signals that its contents are meant to remain undisturbed until a particular moment.

Where does sealed come from?
The word derives from the verb seal, which comes through Old English from the Latin sigillum, meaning a small seal or signet. The form sealed developed as the past tense and past participle of that verb and was subsequently established as an adjective in its own right. Its modern senses continue the older ideas of fastening securely with a seal and preventing access.
How sealed is actually used
The word is formal and especially common in legal, administrative, and technical contexts. When describing something closed securely, it often emphasizes that it has been made tamper-resistant or officially inaccessible.
