Bincai Magnetic Closure Boxes

Product Overview

The book-style magnetic closure photography portfolio box with archival acid-free linen wrap is purpose-built for professional photographers, fine art printers, and galleries who require museum-grade storage and presentation. Manufactured by Guangdong Bincai Color Printing (founded 2003, Foshan, 18,000 sqm, ISO 9001:2015 & FSC-C147399 certified), this box features acid-free, lignin-free, pH-buffered materials throughout — from the 3.0mm archival greyboard core to the Belgian linen wrap and pH-neutral adhesive. The book-style magnetic closure with N52 neodymium magnets opens like a fine volume, and the spine can be foil-stamped with the photographer’s name or collection title. Compatible with ISO 18902:2013 imaging materials storage standards. Daily output reaches 1.7 million boxes on KBA Rapida 105 and Heidelberg CD 102 7+1 UV presses.
