We certify that all polyester films used by Atlantic Protective Pouches are approved by the Library of Congress. Mylar and Melinex are the brand names of DuPont’s polyester films. SKC is another manufacturer of polyester film that is now approved by the Library of Congress.

Polyester is a polymer formed by a condensation reaction of ethylene glycol and terepthalic acid. This uncoated film is strong, uniform, dimensionally stable and inert. The versions of polyester used by Atlantic Protective Pouches are Mylar type D, Melinex type 516, Melinex type 456, and SKC type SH72S. All of these films are approved by the Library of Congress. They are totally transparent and acid-free. The film surface is highly polished to give excellent brilliance and clarity.

The inert quality is the one most responsible for polyester's acceptance as the film of choice in conservation work. Polyester can withstand temperatures down to minus 100 degrees F without getting brittle, and will not begin to soften and melt until temperatures are in excess of 400 degrees F.

These films have no surface coatings that could react with inks, adhesives, paper ingredients, etc. There are no internal additives such as plasticizers, antioxidants, slip agents, anti-block agents, or UV inhibitors, so none can migrate into adjacent materials. They are completely inert.

Reemay (formerly a DuPont product now produced by Reemay, Inc.) is a spun-bonded polyester material with the same chemical properties as polyester film. (Polyester fibers are mated together with heat, pressure and water to form an inert opaque material). Since it is the same polyester material, it
can be heat-sealed to the film to give a porous side to a pouch. Pouches with the Reemay backing are used by many photo collectors.

News about Mylar D:

DuPont has discontinued production of Mylar D. We are now producing pouches made from Melinex 516, Melinex 456, or SKC type SH72S. These films are all listed by The Library of Congress as equivalent archival-grade materials. These films are identical in appearance, chemical structure, and physical properties. I have worked with archival grade polyester films for over 30 years, producing millions of pouches using this material.

Thank you for your interest in our products!
