Kraft Envelopes?

I heard a comment made on another coin site that "if you put the coin in a Kraft Envelope it will look nicer in about a year."
I'm assuming these "Kraft" envelopes enable some type of toning to occur? Has anyone else heard of these Kraft envelopes?

I get it in rolls about a foot in diameter and 2 feet long, and use the paper for wrapping finished machined parts in.
Envelopes are made from this paper in various sizes, and as coindeuse notes, the smaller ones were used to put coins in years ago. The sulpher tones coins, and on silver will turn the coins dark black within a short while. It destroys coins.

It's those really old yellow Kraft envelopes that will in a few decades, ripen a coin into a toned beauty or beast.

<< <i>Would someone please post a "Kraft Envelope" toned coin? >>
This coin was a sort of gold color with lots of PVC residue. After a bath in acetone, and a rinse, the coin toned like this after about a year inside a kraft envelope. It toned thus mainly because the acetone bath removed the film that seems to form on coins over time, allowing them to react with the envelope. I have had bright white coins refuse to tone until bathed in acetone. TomB could explain the cause and effect here.
<< <i>In the old days this was the way many collectors stored their coins. The envelopes had a high sulfur content that could sometimes impart nice colors. I don't think modern envelopes have the same sulfur content.

I have a bunch of the old (dark brown) kraft envelopes. I wonder if the sulfur is still active?
Hey, does anyone else believe the new icon is very befitting to Russ?

Ever hear of "tongue-in-cheek? Russ and I haven't been in litigation, yet.
I cropped this from a post about ACG, where disclaimers are absolutely necessary IMO!
