Bulk Mailing Envelopes 500 Count

These white catalog envelopes arrive in a box of 500 and measure 6 by 9 inches. The 28 pound stock and 92 percent brightness give a clean, professional look for everyday shipping. The open-end design suits catalogs, brochures and multi-page documents. Offices and mailrooms that process high volumes will appreciate the quantity.

Center Seam Pressure Seal

A center seam runs the length of the envelope for added strength during transit. The pressure-sensitive adhesive activates without moisture, so each flap seals quickly by hand. No moistener, tape or heat sealer is required, freeing up bench space and cutting consumable costs. The vellum finish resists smudging during handling.

Vellum Finish 92 Brightness

The vellum surface takes inkjet and laser addresses cleanly without feathering. At 92 percent brightness the white background keeps barcodes and return addresses legible for automated sorting. Buyers who need a glossy coating or a security tint will not find those features here. The plain finish keeps the focus on reliable sealing and consistent print quality.

Questions about this item

Will the 28# paper weight hold up if I stuff these with heavy catalogs every day?

The 28# stock is built for catalog-weight contents and resists tearing during daily bulk mailing.

Do the envelopes stay sealed through heat and humidity in a non-climate-controlled mailroom?

The pressure-sensitive adhesive forms a permanent bond that withstands typical warehouse temperature swings.

My inserter only feeds center-seam envelopes — will this box of 500 work without jams?

Yes, the center-seam construction feeds smoothly through standard inserters designed for that format.
