Product Identity

These open side booklet envelopes measure 9 inches by 12 inches and come in a box of 500. They suit offices, schools and mailrooms that send flat documents, catalogues or booklets without folding. The tan kraft colour and vellum finish give a professional appearance for everyday correspondence.

Build and Sealing

Each envelope uses 28 pound Suntan Kraft paper that carries SFI certification. Two side seams run underneath the body for added strength during handling. The remoistening seal on the flap down closure secures contents without tape or adhesives, while the vellum surface accepts pen, printer toner and labels cleanly.

Upgrade Context

This box replaces smaller packs of lighter weight envelopes when volume rises or when side seam construction is preferred over centre seam styles. The jump is worth it for teams that need consistent sizing, reliable sealing and a certified paper source for regular high quantity mailings.
