WESTERN STATES Open End Catalog Envelopes 8.75 x 11.5 28# White Center Seam 500 Box

Open End Catalog Envelopes 8.75 x 11.5

These open end catalog envelopes measure 8.75 by 11.5 inches and are made from 28 lb white sulphite paper with a vellum finish. The center seam construction and remoistening seal provide a secure closure for documents. Each box contains 500 envelopes and the paper is SFI certified with 92 brightness. They are suited for mailing catalogues, reports and flat documents that need a professional appearance.

Mailrooms sending flat documents

Offices that regularly mail brochures, annual reports or multi-page letters will find the 500 count box practical for high volume use. The vellum finish gives a smooth surface for handwriting or labels. Buyers who need a window envelope for address visibility should look at a different style. Anyone requiring padded protection for fragile items will need a separate mailing product.

28 lb white sulphite paper weight

The 28 lb paper weight determines the envelope stiffness and how much content it can hold without tearing. This weight supports typical catalogues and document sets while remaining light enough for standard postage rates. Heavier inserts may exceed the structural limit of the center seam. Lighter weight envelopes would cost less but offer less rigidity for the same size.
