Pina Zangaro's welded top-loading polypropylene sheet protectors have become the industry standard for high-quality, archival preservation and presentation of artwork and documents.
They allow sheets to lie perfectly flat and are compatible with all major brands of portfolios. They're scratch resistant, and have a non-stick finish.
A thick, black acid-free and lignin-free liner sheet supports thin or fragile artwork.
Portfolio Dimensions — The sizes given for presentation cases, portfolios, binders, and refill pages are the sizes of the artwork they are intended for, not the actual dimensions of the product.
