E. Gerber Fullback vs. Clear PET Board 1 1

[Jay Kurian]

Is one of these better than the other for long term archival? I intend to keep my collection for the next 70 years, and prefer the clear backs so I can see back covers, but wondering if there's any archival concerns with those vs. the full backs.

The clear plastic will not absorb acid, those full back boards might?  Whether a positive or negative that needs to be looked at further.

 interesting reading;
