Looking for the superior clarity of polyester in a sheet that will lie flat in a screwpost book? Look no further than Pina Zangaro’s new Flex-Hinge Polyester Sheet Protectors. These top-and-bottom loading 100% archival sheets are much clearer than polypropylene sheets and they lie perfectly flat thanks to a hinged binding edge. Packed in tens in a protective metallic, resealable bag.
Made of archival grade DuPont polyester (polyethylene terephthalate), these sheets have high transparency and tensile strength, are non-yellowing at ambient temperatures, are chemically and dimensionally stable and are resistant to most chemicals, moisture and abrasion. A non-stick finish prevents adhesion to your artwork. Approved by the Library of Congress for archival storage. Lined with 10 pt. black acid-free and lignin-free paper. Both plastic and paper pass the Photographic Activity Test (PAT) and meet all ANSI requirements for archival storage.
