Foil covered sleeve or foil-covered sleeve?

ryansamturnerIf I were saying, 'I popped two of the pills out from the foil covered sleeve.'
Should I use a hyphen 'foil-covered'?

Yes, you should.

Thanks.

What about 'they were still attached to my heavily chained wrists', would you hyphenate 'heavily-chained'?

No.

Thank you again. Can I ask your advice on a final example.

'Trees and moss-covered mountains were erected.'

That would be correct then?

Yes. Foil-covered, moss-covered, ice-covered, mud-covered—all hyphenated. It doesn’t matter what noun you use.
