WESTERN STATES Open End Catalog Envelopes 10 x 13 28# White Center Seam Pressure Sensitive Seal Box of 500

White sulphite catalog envelopes

These 10 x 13 inch open-end envelopes use 28# white sulphite paper with SFI certification and a vellum finish. The center seam construction provides durability for catalogs, reports and bulky mailings. A pressure-sensitive Kwik-Tak seal closes each flap without moisture or tape. They arrive new in a 500-count box.

Peel-and-seal closure speeds packing

Remove the protective strip and press the flap down to activate the adhesive. No moistener or separate tape is required, so high-volume mailing moves quickly. The release liner must be fully removed before sealing; partial removal leaves gaps that can open in transit. Store boxes flat in a dry area to keep the adhesive tacky.

500 envelopes handle large batch jobs

A single carton supplies 500 units weighing 27 lbs total, suitable for monthly statements, brochures or product samples. The 10 x 13 format fits standard letter-size documents folded once or flat inserts up to that dimension. Very thick catalogs or rigid objects may exceed the flap’s sealing range.
