Double Poly Window Envelope

This double-window envelope measures 4.125 inches by 9 inches and is made from 24 lb white sulphite paper with a vellum finish. It carries SFI certification and 92 percent brightness, plus a black Wesco inside tint for document security. Two side seams and a remoistening seal complete the construction. Supplied in a box of 500 envelopes.

Suited for high-volume mailings

Ideal for businesses that send statements, invoices or cheques where two separate address blocks must show through the windows. The tinted interior helps protect confidential data from being read in transit. Not suited for users who need a single-window format, a different paper weight or a peel-and-seal closure instead of the remoistening flap.

Check window placement before ordering

The top window sits 7/8 inch by 3 inches, positioned 5/8 inch from the left edge and 2-1/4 inches from the bottom. The bottom window measures 1 inch by 4 inches, placed 5/8 inch from the left and 7/8 inch from the bottom. Verify that your printed forms align with these exact window locations and that the 4.125 by 9 inch envelope fits your inserter or mailing equipment.
