My point is that if "PVC" is the main chemical compound that is a concern, then Ziploc bags would be fine.
Ziploc bags are made of polyethylene, just like archival bags. You just don't keep comics in a Ziploc bag because the form factor is wrong.
Yeah, I just found out that Ziploc bags are made out of one material: polyethylene plastic resin. Does that mean it's safe for storing NES carts long term? I've heard some people post some stuff on the web saying that using Ziploc bags to store NES carts will cause the labels to peel off and discolor. This was my main concern.
