Snippet of relevant info I located, covering sheet (7)

I believe the answer is:

tinfoil

'sheet' is the definition.
(tinfoil is a kind of sheet)

'snippet of relevant info i located covering' is the wordplay.
'snippet of' indicates a hidden word.
'TINFOIL' is hidden within 'relevant info i located covering'.

(Other definitions for tinfoil that I've seen before include "Thin metal sheet for wrapping food etc" , "Rolled metal" , "up to wrapping up dope" , "Shiny food wrapping" , "Fine metal" .)

I've seen this clue in The Guardian.
