This comes from the manufacture of our Silver Guard Anti-Tarnish Zip
Bags. I really can’t speak for any others on the market.
“double-checked with our technical director, to answer this
question. He confirmed that Silver-Guard anti-tarnish bags have no
effect on Silver-Guard is a passive tarnish protector for
silver. It does not emit or outgas into the packaging environment.
It only neutralizes the corrosion or tarnish-causing elements
inside. If there is no silver inside the bag, it has nothing to
absorb and neutralize. If the package contains turquoise, for
example, the inherent properties of the poly film protect the gems
against moisture, dirt, and other contaminants. The benefits of
Silver-Guard kick in only when the package contains silver.”
Hope this answers your question.
