This 9.25 x 11.5" PolyEnvelope with Hook-and-Loop Closure for 3-Ring Binders from Itoya is a multi-purpose archival envelope used for school, hobby, office, and home use. The envelope will store and protect digital prints, photographic prints, and documents up to letter size. On the side of the envelope, a flap folds over and fastens to the envelope via the hook-and-loop closure.
Stronger than paper envelopes, the durable polypropylene construction and the heat-welded seams makes the envelope moisture-, stain-, and tear-resistant. Because the polypropylene is also acid-, lignin-, and PVC-free, contents can be stored for long periods of time, and if the envelope is taken out of storage the contents can be easily identified through the clear plastic. In addition, the envelope is three hole-punched for storing within a standard 3-ring binder.
