These 2 mil and 4 mil Print & Poster Sleeves are made of Museum Grade Archival Polyester (Mylar), an inert material of the highest clarity.  Polyester will not discolor, damage, or adhere to items placed inside it. It is a sturdy film that will give extra support to fragile documents.

Use polyester (Mylar) to ensure your collectibles remain in excellent condition for years to come. Polyester is used worldwide in museums, libraries, and archives. Our polyester material is approved by the Library of Congress for archival storage. We use DuPont inert Melinex® or a suitable equivalent. For custom sizes, call for a price quote. 

We have a line of POLYESTER POSTER L-SLEEVES that fit perfectly in our new archival Movie Poster Boxes. The unique construction of L-Sleeves (two adjacent sealed sides) allows for quick and safe insertion and removal of photos and prints.

SUPER ARCHIVAL BACKING BOARD - Our backing board material meets the Library of Congress archival standards. It is 100% alpha-cellulose, .040" thick, acid-free (alkaline pH 8.5), lignin-free, contaminant-free. It comes buffered with a 3% calcium carbonate buffer. Use for indefinite-term storage (hundreds of years).
