WESTERN STATES Open Side Booklet Envelope 6.5 x 9.5 24# White Side Seams Box of 500

Open Side Booklet Envelope 6.5 x 9.5

These envelopes measure 6.5 by 9.5 inches and use 24 lb white sulphite paper with a vellum finish. The open-side design and two side seams suit booklet mailing and document storage. SFI certification confirms responsible fibre sourcing. Each box contains 500 pieces for high-volume office use.

Sustained mailing performance

The side-seam construction resists splitting when envelopes are filled to capacity and processed through folder-inserter machines. Vellum finish reduces static buildup during long print runs on laser or inkjet equipment. Remoistening seals activate reliably after extended storage in dry conditions. Brightness of 92 percent maintains legible barcodes through automated sorting.

Thermals noise and power draw

Paper envelopes generate no heat, noise or electrical load during handling or storage. The 11.5 lb box weight allows single-person lifting without mechanical aid. Flat stacking minimises warehouse footprint and prevents crushing of lower cartons. No environmental controls beyond standard office humidity are required.
