Mylar Dimensions : 7 1/4" x 10-1/2" + 1-1/2 flap Mylites do not have adhesive on them, and require tape for closure (not included). These are heavy duty 4 mil material thickness mylar bags for when you need the absolute best archival protection available. Gerber Mylite 4 Mil Premium Mylar bags are made of biaxially extruded polyester film and offer safe, secure, and long term archival protection for your best comic books, documents, magazines, art, prints, records, and other collectible items.
The protection they offer is far superior to poly bags, which tend to last only 5-10 years before they need to be replaced. Mylar is an extruded polyester film that is simultaneously stretched in two directions to give it maximum strength. It resists penetration by oxygen and other gases approximately 300 times more than polypropylene. It is also several hundred times stronger and more stable.
It offers protection for 100's of years (essentially forever). We are a full-line Master Distributor of Collecting Supplies. We service collectors, eBayers, and stores all over the country.
