<p>[QUOTE=&quot;Conder101, post: 655160, member: 66&quot;]If it is vinyl then PVC is present whether it is pliable or not, that is what vinyl IS Polyvinyl chloride PVC.</p><p><br /></p><p>Having said that I would think that the coins in airtites would be pretty safe.&nbsp; What causes &quot;PVC&quot; damage on coins is the plasticizer used to soften the PVC.&nbsp; The oliy plasticizer gets on the coins and then it absorbs the HCl that PVC plastic outgasses as it ages.&nbsp; It also absorbs water vapor from the air and the two combine to form Hydrochloric acid which the plasticizer then holds against to coins and it attacks the metal.</p><p><br /></p><p>To a lesser extent PVC outgassing can also react with water vapor in the air and cause some hazing on exposed coins.&nbsp; In either case the airtites will prevent plasticizer from getting on the coins and will also tend to keep outgassed HCl from getting to the coin.[/QUOTE]</p><p><br /></p>
