Silver paper, silver foil paper and adhesive. Is there any difference between them?

Self-adhesive is a big category, paper, film and so on are all self-adhesive silver paper is a film made of PET, and silver foil paper is electroplated paper, both of which are small categories of adhesive, including silver paper and silver foil paper.

Of course, these two kinds of paper can only be called self-adhesive (such as labels) after being coated with glue, but they can't be counted if they are used for other purposes.
