Morphology

self-sealing = sealing (transparent) = self + seal + ing

The structure is clearly 'self-' + 'sealing' meaning able to seal itself, which is directly inferable from its parts.

Etymology

Self-sealing comes from self ('itself') and seal ('to close tightly'), so it means 'it closes itself'. Think of a bag or envelope that makes its own tight seal after you open or pierce it, keeping things inside safe.
