Pina Zangaro 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 polypropylene sheets 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. All formats are top-loading. Made of inert, unplasticized, heat resistant and chemically stable archival quality, heavy-duty .0045 polypropylene.
The Polypropylene Express Sheet Protectors have no liner sheet and are punched only for use in screwpost books. The polypropylene has passed the Photographic Activity Test (PAT) and meets all ANSI requirements for archival storage. Package of ten in a protective metallic, resealable bag.
