9 x 12 Envelopes

Flat Document Mailing Without Creases or Folds

Folding valuable documents ruins their clean presentation. Measuring 9 by 12 inches, these spacious catalog and booklet envelopes hold standard 8.5 x 11 letter sheets completely flat. This makes sure that your legal contracts, certificates, and school art projects arrive at their destination in pristine condition.

Booklet Long-Side Insertion vs. Open-End Filing

Select booklet styles with wide long-side flaps for fast, snag-free loading of thick presentation packets and brochures. When you need secure vertical filing or postal delivery for single documents, open-end catalog envelopes feature short-side openings to align papers inside mailbags and storage drawers.

Color Organization, Security Tints and Clasp Closures

Color-code office mailrooms and home workspaces with vibrant shades like royal blue or cheerful yellow, alongside classic white and brown kraft. Choose privacy-tinted interiors to protect sensitive records, with reusable metal clasp closures or peel-and-seal adhesive strips for quick, dependable sealing across large mailing runs.
