The rigidity (4 mil) and unique construction (two adjacent sealed sides) of our Photo L-Sleeves allows for quick and safe insertion and removal of photos. We use DuPont inert Melinex® or a suitable equivalent. The Archival Polyester (Mylar) we use is an inert material of the highest purity and clarity. It has passed the Photo Activity Test, which certifies that the material is approved by the Library of Congress for Indefinte storage.
Note: We manufacture our own polyester sleeves. For sizes, not listed, call for a price quote. Low Minimums.
