Pina Zangaro's classic welded polypropylene sheet protectors have become the industry standard for high quality archival preservation and presentation of artwork and documents. The weld parallel to the binding edge acts as a hinge, allowing the sheets to lie perfectly flat, making these sheets ideal for use in screwpost books. These top-loading Polypropylene Express Sheet Protectors feature superior scratch resistance to make your work look better longer, a non-stick finish to prevent adhesion to your artwork and a non-reflective finish to minimize glare. They have no liner sheet and are punched only for use in screwpost books and 3-ring binders. Packaged in a protective metallic, resealable bag.
Made of inert, unplasticized, heat resistant and chemically stable archival quality, heavy-duty .0045 polypropylene. These sheets have passed the Photographic Activity Test (PAT) and meets all ANSI requirements for archival storage.
Dimensions: 11" x 17" landscape
Holes are punched for use only in screwpost books and 3-ring binders
