Explanation
Anything that's sealed is securely — maybe even permanently — closed or unavailable. An ancient sealed tomb may be safe from curious explorers or grave robbers. A sealed bottle of medicine is tightly shut, not even allowing air inside. A sealed document might be physically closed, like a sealed envelope that's pasted shut, or just unavailable for anyone without special permission to look at.
