WESTERN STATES Open End Catalog Envelopes 9 x 12 20# Tan Brown Kraft Center Seam Box 250

Product Identity

These open-end catalog envelopes measure nine by twelve inches and use twenty-pound tan kraft paper with a vellum finish. The center-seam construction and remoistening seal suit offices, mailrooms and fulfilment operations that ship flat documents, catalogues or lightweight merchandise. Each box contains two hundred fifty envelopes.

Sustained Use Behaviour

The SFI-certified kraft stock resists tearing during repeated packing and handling cycles. Vellum surface texture keeps printed addresses legible after stacking and transit friction. Center seam layout distributes stress evenly when envelopes are filled to capacity, reducing burst failures during high-volume mailing runs.

Compatibility Check

Verify that your postage meter or printer accepts nine-by-twelve-inch open-end format before ordering. Confirm that the remoistening adhesive works with your sealing equipment or manual process. Ensure storage space accommodates the eight-point-five-pound box and that your workflow can process two hundred fifty units per box efficiently.
