Why don't we revisit this topic in 5 years. This is all science. We'll know by then if anything works. All plastic sheets are permeable to gas pollutants whether vacuum sealed or not. The coin Armour bags are impregnanted with compounds that adsorb and neutralize some of the airborne pollutants in the immediate vicinity of the coin. At least that is the proposed mechanism. But it was a good faith FYI for those who have been using those bags for the single coin slabs. It's not a call for ALL to use the bags for the new coin trays.
Beijing and some of china places are so air polluted. How those collectors and dealers in china protect their coins ?
It is amazing that many of them are in good condition even after 10 years or more. I do not believe big dealers with ton of coins/medal protect their stock using coin armour and vacuum seal. It is interesting to find this out.

To answer your question: Get coins graded and slabbed fast if you live in a polluted city. Then mount a second level of protection by enclosing in an airtight container like a glass jar plus desiccant sachets. If you have archival bags use them. If you have vacuumable bags use them. Every bit of protection helps. I read somewhere that adding a fresh piece of copper metal into the container can also adsorb toxic gases similar to archival bags. Best for everyone to keep on researching and experimenting on ways to protect their precious coins.
Silver panda trays were enclosed in sealed plastic sheets until 2016. It is only a step away to put a tiny copper strip in each bag just like they put in all those labels and other inserts into the bags before sealing. That is if they believe that using copper to chelate silver damaging ions work.
This can be a simple issue or a complex one depending on individual's perspectives and inclination.
Yes even those who don't go to these lengths may still end up with excellent coins. Start with simple common sense measures then try more advanced options again depending on your perspective and resources.

I did use electronic dry cabinet and coin armour bag. Majority of the coins are graded.
I run out of space due to limited space in Singapore.
dealers in china never use anything. Look at this photo. Their stuff still in good condition after years

Yes and it is not a snug fit. Coin slides around in pouch. Eventually frosty areas start rubbing off and pvc damage occurs. That's about when the erstewhile bullion coin makes the transition into a full fledged numismatist play!

Older years panda pouch is pvc. Modern years are not if I am not wrong.
Point hitted soundly. This lead to less survival good specimen so price go high

Got my Ag 1-oz'ers (sorry, 30-gram'ers) in recently..
Have to say, not terribly impressed.
Glad I got them, for the most part.
However..
- Minting quality / condition isn't the greatest. I understand it's "just bullion," but my last ones (2014's) were minted better
- Will never be happy about the switch from 1-oz to 30g. That has nothing to do with "standards," but everything to do with $$$
- Still early in the season, and dealers have already been jacking up the premiums & pre-stealing more of the upside. And combined with the above two, at that??
And yes, these are legit ones, purchased from a reputable dealer who's not much into slabbing. Could be wrong, but don't believe these were cherry-picked.
Just not wow'ed like I was with the 2014, for example.
3 strikes and you're out?
I skipped over the 2015's (due to lack of composition, purity & weight) -- and I think the Panda will be on a case-by-case basis for me each year.
Gonna have to wow me with the design (and improve the minting quality) for me to be a future buyer.
My wallet isn't as deep as my shopping list is long, and I think there are better places to spend my money for my collection.
