Professional Mailing Envelopes

Western States 4" x 8.75" white kraft envelopes arrive in a 500-count box for high-volume mailing tasks. The open-end design and thumb-cut opening speed up document insertion at the desk. SFI certification confirms responsible fibre sourcing for every shipment.

Office Teams With Standard Window Needs

These envelopes suit accounts, payroll and compliance teams that send letter-size inserts through a 3" x 6-1/2" cellophane window. The vellum finish takes pen and stamp ink cleanly without smudging. Buyers who require laser-printable stock or a peel-and-seal closure should look at alternative lines.

28# Basis Weight Determines Handling

At 28# basis weight the paper resists tearing during machine stuffing yet stays light enough for standard postage rates. Heavier stocks increase durability but raise mailing costs. Lighter weights cut postage but risk jams in high-speed inserters.

Questions about this item

What window size and position does the 4" x 8.75" envelope have for address visibility?

The cellophane window measures 3" x 6-1/2" and sits 1/2" from the left edge and 1-1/4" from the bottom.

How do you load these open-end envelopes into a printer without jamming?

Not laser compatible — they are designed for hand insertion or inkjet feeding only; the vellum finish and side seam can cause toner fuser jams.

When should the box of 500 be replaced based on paper certification?

SFI certified white kraft maintains 84% brightness; replace when stock runs low or if humidity causes curling that affects the thumb cut opening.
