Source & specs for LP poly outer bags


I know of uline.com, but anyone have other sources for poly bags for LP jackets.

Are bags good, even?

Preferred thickness? 5mil ? 3 mil ?

Do any of you also bag box sets?

Thanks in advance.

I'm told they're effective at protecting the album covers from showing circular disk wear.
For all things to help you archive & protect your collection of anything: www.lightimpressions.com .I believe their bags are 3mil.
I've heard the 5ml bgs greatly improve bass resolution compared to the 3ml ... but be sure to adjust VTA for the extra 2ml when you play a record that has been stored in a 5ml bag.
