WESTERN STATES Poly Window Open Side Booklet Envelope 6x9 24# 500 Box

6 x 9 Poly Window Envelope

These 6 x 9 poly window envelopes suit offices and schools mailing standard booklets or folded documents. The showcase window measures 4 x 7 inches and sits one inch from the left and bottom edges for easy address alignment. A flood-coated black ink exterior gives a professional finish. The box contains 500 envelopes for high-volume mailing tasks.

Remoistening Seal And Side Seams

Each envelope uses a traditional remoistening seal that activates with moisture for a secure closure. Side-seam construction keeps the front panel flat for clean printing or labelling. The vellum finish provides a smooth writing surface. Note that these envelopes are not laser compatible and should not be run through laser printers.

Check Paper Stock And Print Method

Verify that your mailing process uses inkjet printing, handwriting or labels rather than laser printing. Confirm the 6 x 9 inch dimensions match your insert size and that the 4 x 7 inch window position aligns with your address block layout. The 24 lb white kraft paper stock and SFI certification suit standard mailing weight requirements.
