Mylar (Polyester) Sleeves/P.A.T tested. Can YOUR Comic Sleeves say that?

Mylar (Polyester) Sleeves
These 2 mil and 4 mil Comic Book Sleeves are made of Archival Polyester (Mylar) an inert material of the highest clarity. We use DuPont inert Melinex® or a suitable equivalent.
Polyester (Mylar) will not discolor, damage, or adhere to items placed inside it. It is a sturdy film that beautifully displays, timelessly protects, and gives extra support to fragile documents.

**NEW** We have added two styles of 4 mil polyester sleeves. They are both made of the same archival polyester material, but they have two different flap styles. The Open Flap style (ROF) has to be creased to form the flap and then folded over. The Beaded Flap style (BF) has a third piece of polyester that is bead welded to the extended back of the sleeve, creating the flap.

Our polyester material has passed the Photo Activity Test (PAT).http://www.bagsunlimited.com/c-353-mylar-polyester-sleeves.aspx RSS 2.0: http://collectionprotection.blogspot.com/feeds/posts/default?alt=rss
