Pina Zangaro's classic welded polypropylene sheet protectors have become the industry standard for quality. The pocket-style pages are top-loading, and the welded edge allows the pages to lie flat when the portfolio is opened. Recommended for screwpost books, but appropriate for all portfolio books.

Packed in tens in a metallic, reusable bag. Available in standard formats to fit Pina Zangaro books and those from most other major manufacturers. Archival quality heavy-duty .0045 polypropylene. Inert, unplasticized, heat resistant and chemically stable. 10 pt. black acid and lignin-free paper. Both plastic and paper pass the Photographic Activity Test (PAT) and meet all ANSI requirements for archival storage.

For use with: 17x11 Portrait Portfolio Books
